Why

bin/configuration.mk exists only to persist CONFIGURATION=<value> between Unix make invocations. Removing it lets us delete the only meaningful contents of Step_GenerateFiles.Unix.cs, continuing the slow removal of xaprepare (see precedent: #11568, #11529).

What

  • Drop -include bin/configuration.mk from the top of Makefile. The CONFIGURATION ?= Debug fallback at the top of the file is unchanged.
  • Delete build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs entirely (it contained GeneratedConfigurationFile and a one-line AddUnixPostBuildSteps partial that registered it).

The partial void AddUnixPostBuildSteps (Context context, List<GeneratedFile> steps); declaration in Step_GenerateFiles.cs is intentionally left in place — partial methods without an implementation are legal in C#, and the call site becomes a zero-cost no-op. Step_GenerateFiles.Windows.cs implements a different partial (AddOSSpecificSteps) and is unaffected.

Why this is safe

CallerPre-change behaviorPost-change behavior
All CI YAML (build-linux-steps.yaml, build-macos-steps.yaml, commercial-build.yaml, azure-pipelines-apidocs.yaml)Passes CONFIGURATION=$(XA.Build.Configuration) on every make callSame — explicit value still wins
build.sh (make prepare && make jenkins && make pack-dotnet)First make prepare runs against an empty bin/, so the -include no-ops and ?= Debug takes effectIdentical — ?= Debug still takes effect
Fresh local checkout, bare make all?= Debug (no bin/configuration.mk yet)Same
Local dev who runs make prepare CONFIGURATION=Release then bare make allPersisted Release via bin/configuration.mkNow defaults back to Debug — must pass CONFIGURATION=Release on every invocation

That last case is the only behavior change. It was never documented as a contract anywhere in Documentation/ or README.md, and developers building Release locally should be passing the flag explicitly anyway.

Verification

  • git grep "configuration\.mk" and git grep "GeneratedConfigurationFile": zero matches after this change.
  • dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj: 0 warnings, 0 errors.
  • Rubber-duck review: no remaining Path.Combine(..., "configuration.mk") references, no Makefile target depends on bin/configuration.mk as a prerequisite, and the leftover partial-method declaration is benign.

[build] Remove unused bin/configuration.mk
1ad2d35
`bin/configuration.mk` existed only to persist `CONFIGURATION=<value>`
between Unix `make` invocations. CI passes `CONFIGURATION=...` explicitly
on every `make` call, and `build.sh` never sets it (so a fresh checkout
always hit the `CONFIGURATION ?= Debug` default anyway). Dropping the
include lets us delete the only meaningful contents of
`Step_GenerateFiles.Unix.cs`, continuing the slow removal of xaprepare.
- Drop `-include bin/configuration.mk` from the top of `Makefile`. The
`CONFIGURATION ?= Debug` fallback is unchanged.
- Delete `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs`
entirely. The `partial void AddUnixPostBuildSteps (...)` declaration in
`Step_GenerateFiles.cs` is left as a no-op (legal C#); the call site
becomes a zero-cost no-op. `Step_GenerateFiles.Windows.cs` implements a
different partial (`AddOSSpecificSteps`) and is unaffected.

Changes:

  • Removed -include bin/configuration.mk from the repo Makefile.
  • Deleted the Unix-only xaprepare generated-file step that produced bin/configuration.mk.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated 1 comment.

FileDescription
MakefileStops including bin/configuration.mk, leaving CONFIGURATION ?= Debug as the sole default mechanism.
build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.csRemoves the generator that created bin/configuration.mk and the Unix partial-step registration.

Drop now-dead AddUnixPostBuildSteps partial

After deleting `Step_GenerateFiles.Unix.cs`, the `partial void
AddUnixPostBuildSteps (...)` declaration and its call site in
`Step_GenerateFiles.cs` were no-ops. Remove them so the file no longer
references a vestige of the `bin/configuration.mk` generator.

[xaprepare] Check inMono.Android.Apis.projitems, remove generator (#…
63951b8
…11608)
`Mono.Android.Apis.projitems` was previously generated at prepare time by
`GeneratedMonoAndroidProjitemsFile` (in xaprepare) from the
`BuildAndroidPlatforms.AllPlatforms` list. Both had exactly one consumer
(each other), so check in the projitems as a source file and drop the
generator plumbing.
Changes:
* Add `src/Mono.Android/Mono.Android.Apis.projitems` — content matches
the generator's output byte-for-byte; only the header comment now
points at `Documentation/workflow/HowToAddNewApiLevel.md` instead of
declaring "GENERATED FILE".
* Repoint the 4 importers (`Mono.Android.targets` x2,
`create-installers.targets`, `create-android-api.csproj`,
`Xamarin.Android.Build.Tasks.targets`) at the new path and drop the
`Condition="Exists(...)"` guards — the file is always present now.
* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* [Xamarin.AndroidTools] Remove dead VS Mac / legacy code (#11607)
Context: after the `android-platform-support` repo was inlined here
(see c22cdcf), `src/Xamarin.AndroidTools/` carries a large amount of
code that was only used by old VS Mac / installer / debugger-host
workflows that are no longer part of the .NET for Android product. None
of these types have callers anywhere in this repo, in
`external/xamarin-android-tools/`, or in `external/Java.Interop/`.
Removed (13 files):
* `PublicationUtilities/PublishAndroidApplication.cs`
* `PublicationUtilities/PackageSigningTasks.cs`
* `PublicationUtilities/KeyManagement.cs`
* `PublicationUtilities/KeystoreEntry.cs`
* `Sessions/AndroidDeploySession.cs`
* `Sessions/AndroidConnectCommandSession.cs`
* `Sessions/AndroidCommandSession.cs`
* `Sessions/AndroidDeploymentException.cs`
* `Devices/AndroidPackageList.cs`
* `Devices/AndroidPackageListExtensions.cs`
* `Debugging/MonoDroidProcessMonitor.cs`
* `PlatformPackage.cs`
* `IProgressNotifier.cs`
* `AndroidSigningOptions.cs`
Moved (still needed by `ProcessUtils.cs`):
* `PublicationUtilities/AndroidSdkToolException.cs` ->
`AndroidSdkToolException.cs` (namespace unchanged)
Pruned from `Devices/AndroidDeviceExtensions.cs` (the methods only
referenced the just-deleted types and had no in-tree callers):
* `StartActivityWithCommandSession` (used `AndroidCommandSession`)
* `GetDeploySession`, `GetPackagesAsync`, `GetPackages` (used
`AndroidDeploySession` / `IProgressNotifier`)
* `InstallSharedRuntime*` and `InstallSharedPlatform*` overloads
that took `IProgressNotifier`
* `GetPackageRemotePath`/`GetPackageRemotePathAsync` (used
`AndroidDeploymentException`)
* `GetFastDevRemotePath`/`GetFastDevRemotePathAsync` and the inner
`FastDevRemotePathInfo` class (only consumer was
`GetPackageRemotePathAsync`)
Kept methods in `AndroidDeviceExtensions.cs` are the ones still used
by `Xamarin.Android.Build.Debugging.Tasks` (`EnsureProperties`,
`KillProcessAndWaitForExit`, `PushAndInstallPackageAsync`) and by
`DebuggingExtensions` (`SetFastDevPropertyFile`, `GetProcessIDAsync`,
`SetDebugPropertiesAsync`).
Also cleaned up:
* `Properties/Resources.resx` (English source): removed seven
`CreateKeyError_*` strings that only `KeyManagement.cs` used.
* `Properties/Resources.Designer.cs`: removed the seven matching
properties.
* `MonoDroidSdk.cs`: two `[Obsolete]` messages referenced the
now-deleted `PlatformPackage`; changed to `"Do not use."`.
Non-English `Resources.*.resx` and `Localize/loc/**/*.lcl` are left
alone per repo policy (auto-regenerated by OneLocBuild).
Build verified locally:
* `src/Xamarin.AndroidTools/Xamarin.AndroidTools.csproj`
* `src/Mono.AndroidTools/Mono.AndroidTools.csproj`
* `src/Xamarin.Android.Build.Debugging.Tasks/Xamarin.Android.Build.Debugging.Tasks.csproj`
* `src/Xamarin.Installer.AndroidSDK/Xamarin.Installer.AndroidSDK.csproj`
Net change: -4225 / +2 lines across 19 files.

* [NUnitLite] Add OneTimeSetUp/OneTimeTearDown attribute shims
NUnit 3.x renamed [TestFixtureSetUp]/[TestFixtureTearDown] to [OneTimeSetUp]/[OneTimeTearDown]. dotnet/java-interop#1437 migrated the Java.Interop test suite to the new names.
The bundled Xamarin.Android.NUnitLite (src-ThirdParty/NUnitLite/) only defines the legacy names. Add no-op subclasses for the new names so test source using [OneTimeSetUp]/[OneTimeTearDown] still compiles against bundled NUnitLite once the Java.Interop submodule is bumped past dotnet/java-interop#1437.
These shims become unnecessary once dotnet/android moves off bundled NUnitLite to stock NUnit (tracked in PR #11224).

[build] Remove Step_PrepareProps; fold values into eng/Versions.props (…
ee0392c
…#11613)
Continues the slow `xaprepare` removal. Recent precedent: #11568 (CopyExtraResultFilesForCI → YAML), #11580 (configuration.mk removal), #11529 (android-platform-support consolidation, which also dropped `Step_PrepareExternalGitDependencies`).
## What
`Step_PrepareProps` generated `external/Java.Interop/Configuration.Override.props` (inside the submodule) by substituting two placeholders into `build-tools/scripts/Configuration.Java.Interop.Override.in.props`. The substituted properties (`_XamarinAndroidCecilVersion`, `UtilityOutputFullPathCoreApps`, `XamarinAndroidToolsDirectory`) are now supplied directly via the checked-in static file `external/Java.Interop.override.props`, which Java.Interop's own `Directory.Build.props` already auto-imports via the parent-dir convention added in dotnet/java-interop#872.
The shared version values (`MonoCecilVersion`, `AndroidPackVersion`, `AndroidPackVersionSuffix`) move into `eng/Versions.props`. `Directory.Build.props` and `external/Java.Interop.override.props` both `<Import>` it. No duplicate-import sentinel is needed because every code path that imports `Configuration.props` has already loaded `Directory.Build.props` (either via MSBuild auto-load or via the explicit `<Import>` in `external/xamarin-android-tools.override.props`).
`MicrosoftAndroidSdkPackName` stays in `Configuration.props` (it is OS-conditioned, not version-shaped, so it doesn't belong in `Versions.props`). The same 3-line OS-conditioned block is mirrored privately in `external/Java.Interop.override.props` as `_MicrosoftAndroidSdkPackName`, used only to compute `UtilityOutputFullPathCoreApps` for the Java.Interop build.
Also dropped:
- `Configurables.Paths.InstallMSBuildDir` and its backing field — the only consumer was `Step_PrepareProps`.
- The dead `UtilityOutputFullPath` line in the old template — Java.Interop's `TargetFrameworkDependentValues.props` unconditionally routes it to `$(UtilityOutputFullPathCoreApps)` anyway, so it was a no-op.
Updated `build-tools/scripts/XAVersionInfo.targets` (the `GitBlame` for `<AndroidPackVersion>` now points at `eng/Versions.props`) and `Documentation/guides/HowToBranch.md` to reflect the moves.
## Why not just `<Import>` `Directory.Build.props` from the Java.Interop override?
That was the original idea. I prototyped it: importing dotnet/android's full props chain from `external/Java.Interop.override.props` flips `DotNetTargetFrameworkVersion` from `10.0` to `11.0` inside Java.Interop, and `dotnet restore Java.Interop.csproj` then fails with:
```
NETSDK1045: The current .NET SDK does not support targeting .NET 11.0
```
`xamarin-android-tools.override.props` gets away with the same trick only because its sole csproj sets `AndroidToolsDisableMultiTargeting=true`, which makes the TFM-clobber harmless. Java.Interop has no equivalent escape hatch.
`eng/Versions.props` is collision-free with Java.Interop (verified against the submodule sources — none of the existing entries collide), has no `<Import>` of its own, and is the safe minimal shared file.
## Verification
On Windows:
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj` — 0 warnings, 0 errors.
- From `src/Xamarin.Android.Build.Tasks/`: `dotnet msbuild --getProperty:MonoCecilVersion,AndroidPackVersion,AndroidPackVersionSuffix,MicrosoftAndroidSdkPackName,MicrosoftAndroidSdkOutDir` — values unchanged from baseline.
- From `external/Java.Interop/src/Java.Interop/`:
- `dotnet msbuild --getProperty:DotNetTargetFramework,_XamarinAndroidCecilVersion,UtilityOutputFullPathCoreApps` returns `net10.0`, `0.11.5`, the expected packs/tools path.
- `dotnet restore Java.Interop.csproj` succeeds (no `NETSDK1045`).

[build] Remove omnisharp.json generation from xaprepare (#11631)
58ccc1f
### Context
`Get_Omnisharp_Json` in `Step_GenerateFiles` substituted two placeholders into `build-tools/scripts/omnisharp.json.in` and wrote `omnisharp.json` at the repo root for OmniSharp / VS Code C# extension users. The generated file was always `.gitignore`d and **nothing in the repo, build, or CI consumes it** — it was purely a local-dev convenience.
Anyone who actually wants an `omnisharp.json` can keep their own local copy (it remains gitignored). Removing this generation slice is another small step in the slow xaprepare reduction, continuing the pattern from #11568, #11580, #11608, and #11613.
### Audit
Before this change `git grep -in "omnisharp"` returned five hits. After it returns only one — the unrelated MSBuild-context guard in `xaprepare.csproj` that prevents xaprepare's targets from importing under OmniSharp's MSBuild process:
```
build-tools/xaprepare/xaprepare/xaprepare.csproj:52:
<Import Project="xaprepare.targets" Condition=" $(MSBuildToolsPath.IndexOf('omnisharp')) < 0 " />
```
That guard is intentional and is **not** touched by this PR.
### Changes
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`: drop the `Get_Omnisharp_Json (context)` entry from the generated-files list and delete the `Get_Omnisharp_Json` method.
- Delete `build-tools/scripts/omnisharp.json.in`.
The shared properties used by the deleted method (`MicrosoftDotnetSdkInternalPackageVersion`, `DotNetPreviewPath`) are still referenced by `Step_InstallDotNetPreview` and `xaprepare.targets`, so they remain.
### Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` — 0 warnings, 0 errors.
- `git grep -in "omnisharp"` — returns only the unrelated `xaprepare.csproj` guard described above.
- No `Documentation/` references to omnisharp; no `.vscode/` folder in the repo.
- Diff: 3 files, 35 deletions, 0 additions.

[xaprepare] Check in Ndk.projitems, remove generator (#11733)
dc54c1c
Mirrors #11608 (which checked in `Mono.Android.Apis.projitems` the same way). See also #11568, #11580, #11613, #11631, #11657, #11658.
## What
`build-tools/scripts/Ndk.projitems.in` was a template with `@NDK_*@` placeholders that the `Get_Ndk_projitems` generator in xaprepare filled in from constants in `BuildAndroidPlatforms.cs`. Those substitution values only change on rare NDK bumps, so generating the file on every build adds no value.
This PR checks in the resolved file as a static `build-tools/scripts/Ndk.projitems` and removes the generator.
## Changes
- **Add** `build-tools/scripts/Ndk.projitems` — the static, checked-in file. Rather than hardcoding values, it sources them from the existing properties in `Configuration.props` (which is imported before `Ndk.targets`):
- `AndroidNdkVersion` → `$(_XAAndroidNdkRelease)`
- `AndroidNdkPkgRevision` → `$(_XAAndroidNdkPkgRevision)`
- the per-ABI `AndroidNdkApiLevel_*` → `$(AndroidMinimumDotNetApiLevel)`
So there is nothing to keep in sync on an NDK/API bump.
- **`build-tools/scripts/Ndk.targets`** — point `ProjitemsFile` at the new in-tree location (`$(MSBuildThisFileDirectory)Ndk.projitems`) instead of `bin/Build$(Configuration)/Ndk.projitems`.
- **Delete** `build-tools/scripts/Ndk.projitems.in`.
- **`Step_GenerateFiles.cs`** — remove the `Get_Ndk_projitems` method and its dispatch entry.
- **`Configurables.cs`** — update a doc comment reference from `Ndk.projitems.in` → `Ndk.projitems`.
### Simplifications (from review)
- **Collapsed the dead legacy/NET API-level split.** The legacy 32-bit minimum API level used to be lower than the .NET minimum, but they are identical now. Removed the two per-ABI properties that nothing references (`AndroidNdkApiLevel_Arm`, `AndroidNdkApiLevel_X86_Legacy`). The `arm64-v8a`/`x86_64` properties are kept because shipped targets (`Build.Tasks.targets`, `Common.props.in`, `NativeAOT.targets`) still consume them by name.
- **Removed the `ApiLevelNET` item metadata.** `ApiLevelNET` was the .NET (.NET 6+) Android minimum API level vs. the legacy Xamarin.Android/Mono `ApiLevel`; the two are identical now and this repo is .NET-only. Its only consumer was `src/native/common/libunwind/libunwind-xamarin.targets`, which now reads `ApiLevel`. Dropped `ApiLevelNET` from all four `AndroidSupportedTargetJitAbi` items.
The NDK constants in `BuildAndroidPlatforms.cs` are intentionally left untouched — they're still consumed by `Get_XABuildConfig_cs` and the cmake presets generator.
## Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 errors / 0 warnings.
- Evaluated the import chain via a standalone MSBuild harness (importing the real `Configuration.props`); it produces all four `AndroidSupportedTargetJitAbi` items with `ApiLevel`=24 and the expected `AndroidRID` metadata, matching prior generator output (NDK `28c` / pkg `28.2.13676358`).
- Audits clean: `git grep Ndk.projitems.in`, `git grep Ndk_projitems`, `git grep ApiLevelNET`, and the old `bin/Build$(Configuration)/Ndk.projitems` path all return 0 hits.

[xaprepare] Remove unused tool runners and helper classes (#11740)
185bf46
Many xaprepare provisioning steps have been removed over the past year (#11332, #11348, #11399, #11440, #11441, #11636 and follow-up cleanups in #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737). The supporting scaffolding around those steps was left behind. This PR removes the verified-dead pieces in two passes.
## Files removed (first pass — original audit)
| File | Justification |
| --- | --- |
| `Application/TestAssembly.cs` | Orphan test infra; only referenced by `TestAssemblyType.cs`. |
| `Application/TestAssemblyType.cs` | Only referenced by `TestAssembly.cs`. |
| `Application/StepWithDownloadProgress.cs` | No subclasses remain. |
| `Application/NDKTool.cs` | NDK provisioning moved to MSBuild in #11440. Last consumer was the also-dead `Configurables.NDKTools` collection (removed below). |
| `ToolRunners/SnRunner.cs` | Strong-naming tool runner; never instantiated. |
| `ToolRunners/SnRunner.OutputSink.cs` | Partial sibling of `SnRunner`. |
| `ToolRunners/CMakeRunner.cs` | Never instantiated. |
| `ToolRunners/CMakeRunner.OutputSink.cs` | Partial sibling of `CMakeRunner`. |
## Files removed (second pass — repo-wide re-audit)
| File | Justification |
| --- | --- |
| `ToolRunners/MakeRunner.Linux.cs` | Partial of `MakeRunner`; type never instantiated. |
| `ToolRunners/MakeRunner.MacOS.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.OutputSink.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MSBuildRunner.cs` | Never instantiated. |
| `ToolRunners/MSBuildRunner.OutputSink.cs` | Partial sibling of `MSBuildRunner`. |
| `ToolRunners/NinjaRunner.cs` | Never instantiated. |
| `ToolRunners/NinjaRunner.OutputSink.cs` | Partial sibling of `NinjaRunner`. |
| `Application/ScenarioNoStandardEndSteps.cs` | Abstract class with zero subclasses. |
## Cascading cleanup
- `ConfigAndData/Configurables.cs` — removed the dead `NDKTools` `List<NDKTool>` collection (lines 132–145). Rest of the file unchanged.
## Removed from initial deletion list after verification
- `Application/Extensions.DictionaryOfProgramVersionParser.cs` — initial name-only audit flagged it as dead, but its `Add` extension method is consumed via dictionary collection-initializer syntax in `Application/VersionFetchers.cs`. The consumer never references the static class by name, which is why the first audit missed it. The file stays.
- `Scenarios/Scenario_Required.cs` — looks unreferenced by static grep, but `Scenario` subclasses are reflectively discovered via the `[Scenario]` attribute in `Context.cs` (`Utilities.GetTypesWithCustomAttribute<ScenarioAttribute> ()`). Live. The file stays.
## Verification
- `git grep -n -w <TypeName>` for each deleted type now returns 0 real hits (only unrelated `"TestAssembly"` string literals in `tests/Microsoft.Android.Sdk.TrimmableTypeMap.Tests/` remain — those are assembly-name strings, not the C# type).
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 warnings, 0 errors.
## Deferred follow-up
The csproj conditionally excludes `*MacOS*` files from compilation when `HostOS != Darwin`, so static dead-code analysis from a Windows/Linux host can't see whether the macOS-only consumers are themselves live. These candidates need verification on a Mac host (or a build matrix) before deletion:
- `Application/PkgProgram.MacOS.cs`
- `Application/HomebrewProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
- `ConfigAndData/Dependencies/MacOS.cs`

[xaprepare] Move CMake file generation into a dedicated MSBuild proje…
5e9346d
…ct (#11760)
Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.
## What changes
Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:
* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.
Both are now generated by a new project:
* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.
### Why a dedicated project (not just a target in `native.targets`)
The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:
* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).
A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.
### Incremental correctness
`_GenerateCMakeFiles` declares fully-anchored `Inputs`:
* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)
so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)
### Cascading deletions in xaprepare
* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.
`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).
### What stays
The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.
## Verification
On Windows:
* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors
Incremental behaviour verified by walking through MSBuild diagnostic output:
* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.
The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.

[xaprepare] Remove vestigial OS dependency provisioning (#11803)
e89fded
### Context
After #11636 (dotnet provisioning step removed) and #11731 (test-deps scenarios removed), `Context.AutoProvision` is `false` by default everywhere except hand-run dev provisioning, which is no longer in use. The per-OS package lists are populated at `OS.Init()` time but `EnsureDependencies` is effectively a no-op:
- `OS.EnsureDependencies()` returns early when `AutoProvision` is false (the default),
- nothing else in the codebase reads from the `Program` derivatives' install/uninstall paths,
- the `BuildToolsInventory` writer remains driven only from `EssentialTools.MacOS.cs` (homebrew version detection).
The `OS.Init() / InitializeDependencies() / EnsureDependencies()` machinery on `OS.cs` itself is intentionally **left in place** here — that's a larger refactor for a follow-up PR. This PR only strips the now-vestigial package-list data and the program/runner classes that fed it.
### Files deleted (Phase F — macOS, 4 files)
- `Application/HomebrewProgram.MacOS.cs`
- `Application/PkgProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
### Files deleted (Phase G — Linux, 5 files)
- `Application/Program.Linux.cs` (`LinuxProgram` base — orphan after subclasses go)
- `Application/Program.ArchLinux.cs`
- `Application/Program.DebianLinux.cs`
- `Application/Program.FedoraLinux.cs`
- `Application/Program.GentooLinux.cs`
### Files deleted (Phase 3 — orphan)
- `Application/IBuildInventoryItem.cs` (only implementor was `HomebrewProgram`; `BuildToolsInventory` itself stays, populated directly by `EssentialTools.MacOS.cs`).
### Files reduced to empty stubs
`ConfigAndData/Dependencies/`:
- `MacOS.cs` — `InitializeDependencies()` no-op (was Homebrew formula list + git fallback).
- `Linux.Arch.cs` — class kept (referenced by `distroMap`); package list removed.
- `Linux.Fedora.cs` — same.
- `Linux.Gentoo.cs` — same.
- `Linux.DebianCommon.cs` — common Debian/Ubuntu package list removed; `Flavor = "Debian"` kept.
- `Linux.UbuntuCommon.cs` — `libtoolPackages` + `NeedLibtool` virtual + `InitOS` override removed (all dead).
- `Linux.Debian.cs` — all per-version package lists (`packages`, `packagesPre10`, `packagesPreTrixie`, `packagesTrixieAndLater`, `packages10AndNewerBuildBots`) removed; release/codename detection (`EnsureVersionInformation`, `DebianUnstableVersionMap`, `IsDebian10OrNewer`, etc.) preserved as conservative scope.
- `Linux.Ubuntu.cs` — `preCosmicPackages`, `cosmicPackages`, `preDiscoPackages` lists + `NeedLibtool` override removed; `UbuntuRelease` + `EnsureVersionInformation` preserved.
- `Linux.Mint.cs` — `NeedLibtool` override removed (the property is gone from the base).
`ConfigAndData/Dependencies/Windows.cs` was already a no-op stub — no edit.
### Verification
Orphan audit (each `git grep -nw <Type> -- 'build-tools/xaprepare/*'` reports **0 hits**):
- `HomebrewProgram`, `PkgProgram`, `BrewRunner`, `PkgutilRunner`
- `ArchLinuxProgram`, `DebianLinuxProgram`, `FedoraLinuxProgram`, `GentooLinuxProgram`, `LinuxProgram`
- `IBuildInventoryItem`
Build:
```
dotnet build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug
Build succeeded. 0 Warning(s) 0 Error(s)
```
### Out of scope (follow-up)
- Removing the abstract `OS.InitializeDependencies()` declaration and the surrounding `EnsureDependencies()` machinery from `OperatingSystems/OS.cs`.
- `VersionFetchers` / `ProgramVersionParser` / `RegexProgramVersionParser` / `SevenZipVersionParser` / `Extensions.DictionaryOfProgramVersionParser.cs` are kept — `Utilities.GetProgramVersion` still queries them from `Program.cs`, `ToolRunner.cs`, `EssentialTools.MacOS.cs`, and `OperatingSystems/MacOS.cs` (brew detection).
### Precedent
#11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740, #11760

[xaprepare] Move XABuildConfig generation to AndroidBuildConfig.dll (#…
788d363
…11826)
## Summary
Moves `XABuildConfig.cs` generation out of `xaprepare` and into a new strong-named class library at `src/AndroidBuildConfig/AndroidBuildConfig.csproj` that produces `AndroidBuildConfig.dll`.
This continues the incremental removal of `xaprepare`, following the precedent set by `cmake-config.csproj` (#11760) and the recent batch #11568, #11580, #11608, #11613, #11631, #11731, #11732, #11733, #11737, #11740, #11803, #11821, #11825.
It also fixes a long-standing wart: previously `XABuildConfig.cs` was `<Compile Include>`'d into three different assemblies (`Xamarin.Android.Build.Tasks`, `Xamarin.ProjectTools`, and `Xamarin.Android.Build.Tests`), so every test that mentioned `XABuildConfig` produced a `CS0436` "type conflicts with imported type" warning — about **22** of them.
Wrapping the type in its own assembly collapses it to a single definition that every consumer references normally. After this change `Xamarin.Android.Build.Tests` builds with **7** warnings (none for `XABuildConfig`).
## How it works
`src/AndroidBuildConfig/AndroidBuildConfig.csproj`:
- `Microsoft.NET.Sdk` / `netstandard2.0`, strong-named with `product.snk`.
- `ProjectReference`s `Xamarin.Android.Tools.AndroidSdk` (for the `AndroidTargetArch` enum used by the template).
- `<UsingTask>`s `ReplaceFileContents`, `GitCommitHash`, and `GitBranch` from `$(PrepTasksAssembly)`, all with `TaskFactory="TaskHostFactory" Runtime="NET"` per repo convention.
- The `_GenerateXABuildConfig` target runs `BeforeTargets="BeforeCompile;CoreCompile"`, computes every substitution from MSBuild properties already exposed by `Configuration.props` (NDK major/minor/micro via `$(_XAAndroidNdkPkgRevision.Split('.'))`, API levels via `Split`/`Contains`, full commit hash via `GitCommitHash.CommitHash`, branch via `GitBranch.Branch`), and writes the file to `$(IntermediateOutputPath)XABuildConfig.cs`. The `<Compile Include>` lives inside the target so it resolves at execution time, when `IntermediateOutputPath` is final.
- `XABuildConfig` is now `public static class` instead of `internal static class`.
The three consumer csprojs lose their `<Compile Include="…XABuildConfig.cs" />` and now have a normal `<ProjectReference Include="…AndroidBuildConfig.csproj" />` (no `ReferenceOutputAssembly="False"`).
`build-tools/installers/create-installers.targets` ships `AndroidBuildConfig.dll` + `.pdb` alongside `Xamarin.Android.Build.Tasks.dll`.
## xaprepare cleanup
Removed dead code that only existed to feed the old `Get_XABuildConfig_cs` step:
- `Step_GenerateFiles.Get_XABuildConfig_cs` and its `GetMajor` / `GetMinor` locals
- `BuildInfo`: `NDKRevision`, `NDKVersionMajor`, `NDKVersionMinor`, `NDKVersionMicro`, `NDKVersion`, `XACommitHash`, `XABranch`, `GatherGitInfo`, `DetermineXACommitInfo`, `cachedNdkVersion`
- `Context`: the `if (SelectedScenario.NeedsGitBuildInfo) { await BuildInfo.GatherGitInfo … }` block
- `Scenario.NeedsGitBuildInfo` (and the `NeedsGitBuildInfo = true;` setters in `Scenario_Standard` and `Scenario_Required`)
- `BuildAndroidPlatforms.cs` — entire file (only contained constants used by the deleted code)
- `Utilities.ParseAndroidPkgRevision`
- `GitRunner.GetTopCommitHash` and `GitRunner.GetBranchName` (class retained — still used by `BuildInfo.DetermineLastVersionChangeCommit`)
## Files
**Added**
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
**Renamed/moved**
- `build-tools/scripts/XABuildConfig.cs.in` → `src/AndroidBuildConfig/XABuildConfig.cs.in` (`static class` → `public static class`)
**Modified**
- `src/Xamarin.Android.Build.Tasks/Xamarin.Android.Build.Tasks.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.ProjectTools/Xamarin.ProjectTools.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Xamarin.Android.Build.Tests.csproj`
- `build-tools/installers/create-installers.targets`
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`
- `build-tools/xaprepare/xaprepare/Application/BuildInfo.cs`
- `build-tools/xaprepare/xaprepare/Application/Context.cs`
- `build-tools/xaprepare/xaprepare/Application/Scenario.cs`
- `build-tools/xaprepare/xaprepare/Application/Utilities.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Standard.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Required.cs`
- `build-tools/xaprepare/xaprepare/ToolRunners/GitRunner.cs`
- `build-tools/xaprepare/README.md`
**Deleted**
- `build-tools/xaprepare/xaprepare/ConfigAndData/BuildAndroidPlatforms.cs`
## Verification
- `AndroidBuildConfig.csproj`: 0 warnings, 0 errors.
- `Xamarin.Android.Build.Tasks.csproj`: 0 errors, 85 pre-existing unrelated warnings (none for `XABuildConfig`).
- `Xamarin.Android.Build.Tests.csproj`: 0 errors, **7** warnings — down from ~22; all `CS0436 XABuildConfig` conflicts eliminated.
- `xaprepare.csproj`: 0 warnings, 0 errors.
- Generated `XABuildConfig.cs` is semantically identical to the pre-change xaprepare output. The only token difference is the intentional `static class` → `public static class`; everything else (NDK split, API-level major/minor split, supported-ABIs semicolon list, full commit hash, branch name, etc.) matches the previous baseline byte-for-byte.

[xaprepare] Move cgmanifest.json generation from xaprepare to YAML (#…
c7c9458
…11825)
Continues the incremental removal of `xaprepare` by moving the
`cgmanifest.json` generator out of the C# step
`Step_GenerateCGManifest` and into a YAML `pwsh:` step that runs only
on CI.
The file is consumed exclusively by the Azure DevOps Component
Governance Detection task (auto-injected on internal pipelines by
`eng/common/core-templates/job/job.yml`). It is not consumed by any
in-repo build target, so generating it from the C# Prepare step is no
longer necessary.
We cannot drop the file outright: `eng/common` ships CG infrastructure
but it is not yet wired to auto-discover submodules in our pipelines,
so the explicit `cgmanifest.json` is still the source of truth.
Files:
* Added: `build-tools/automation/yaml-templates/generate-cgmanifest.yaml`
* Modified: `build-windows-steps.yaml`, `build-macos-steps.yaml`,
`build-linux-steps.yaml`, `commercial-build.yaml` (call the new
template after the Prepare/`make jenkins` step)
* Modified: `Scenario_Standard.cs` (drop registration)
* Modified: `GitRunner.cs` (remove now-unused `ConfigList` and
`SubmoduleStatus` methods)
* Deleted: `Step_GenerateCGManifest.cs`
Verification: byte-for-byte diff of the YAML-generated
`cgmanifest.json` against the previous C# output on Debug:
Baseline=3144 New=3144
Total byte differences: 0
Precedent PRs in this stream: #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803,
#11821.
### Simplify generate-cgmanifest.yaml using ConvertTo-Json
Replace the hand-rolled StringBuilder JSON emission with PowerShell's
`ConvertTo-Json`. The output is no longer byte-identical to the
previous C# output (2-space indent instead of 4, and slightly
different whitespace), but it is still valid JSON matching the
component-detection-manifest schema. The Azure DevOps Component
Governance Detection task parses the file, so formatting does not
matter.

[xaprepare] Delete redundant Windows JdkInfo.props generator (#11946)
e18dc17
On Windows, xaprepare's Step_GenerateFiles.Windows.cs writes
external/Java.Interop/bin/Build$(Configuration)/JdkInfo.props from
build-tools/xaprepare/xaprepare/Resources/JdkInfo.Windows.props.in.
But this file is immediately overwritten. The PrepareWindows.targets
Prepare flow runs, in order:
1. `dotnet xaprepare -a` — writes JdkInfo.props (this code).
2. `MSBuild Xamarin.Android.BootstrapTasks.sln` — does not read JdkInfo.props.
3. `MSBuild src/workloads/workloads.csproj` — does not read JdkInfo.props.
4. `CallTarget PrepareJavaInterop` → `dotnet build -t:Prepare Java.Interop.sln`
→ external/Java.Interop/build-tools/scripts/Prepare.targets → runs the
`JdkInfo` MSBuild task → overwrites JdkInfo.props with its own generated
content.
Nothing between step 1 and step 4 reads the file, and Java.Interop's Prepare
always regenerates it. Now that external/Java.Interop is in-tree, we can
safely delete the redundant write.
This is the smallest-diff removal:
* Delete Step_GenerateFiles.Windows.cs (the AddOSSpecificSteps partial).
* Delete Resources/JdkInfo.Windows.props.in.
* In Step_GenerateFiles.cs, drop the `partial void AddOSSpecificSteps`
declaration and collapse GetFilesToGenerate so `atBuildStart == false`
returns null. Ctor surface (atBuildStart, onlyRequired) is unchanged so
Scenario_Required.cs is unaffected.
* In Scenario_Standard.cs, remove the AddEndSteps override — the only
thing it did was schedule the now-empty Step_GenerateFiles(atBuildStart:
false).
Preserved (future slices will address these):
* Get_Configuration_OperatingSystem_props (D1).
* OperatingSystems/*.cs and Context.OS.* surface.
* PrepareWindows.targets, DotNet.targets, Java.Interop's Prepare.targets.
Verification:
* dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug
→ Build succeeded. 0 Warning(s). 0 Error(s).
* build.cmd -t:Prepare -c Debug (Windows, cold tree) → succeeds; the file
external/Java.Interop/bin/BuildDebug/JdkInfo.props exists.
* Compare-Object of the resulting JdkInfo.props before vs after this
change → byte-identical (1493 bytes, SHA256
DE59A8061B7657831788FFED7BC1DEECA442E9181605083A4553DE7AC8C003A1),
confirming Java.Interop's overwrite is what always ends up on disk.
* Grep audit under build-tools/xaprepare/: no remaining references to
Step_GenerateFiles.Windows, JdkInfo.Windows.props.in, or
AddOSSpecificSteps.

[xaprepare] Delete Configuration.OperatingSystem.props generator and …
be5272c
…xaprepare project (#11959)
Follow-up to #11956, which moved the JDK half of `Configuration.OperatingSystem.props` to Java.Interop's `JdkInfo.props`. The remaining NDK / OS-info half has zero real consumers, so this PR:
1. Deletes the last generator template (`Configuration.OperatingSystem.props.in`).
2. Cascades through `Step_GenerateFiles`, both `Scenario_*` classes (which now had zero steps), and every supporting `OperatingSystems/`, `Context.*OS.cs`, `EssentialTools.*`, `ToolRunners/*`, `Configurables.*`, `Application/*`, and `Main.cs` file that only existed to feed the scenarios.
3. Deletes the whole `build-tools/xaprepare/` project.
4. Patches every integration point (`Makefile`, `PrepareWindows.targets`, `BuildEverything.mk`, CI YAML, docs) so `build.cmd -t:Prepare` and `make prepare` still work end-to-end.
## `Configuration.OperatingSystem.props.in` placeholder audit
| Placeholder | Consumers outside the `.in` file | Action |
| --- | --- | --- |
| `HostOsName` | none | drop |
| `HostOsFlavor` | none | drop |
| `HostOsRelease` | none | drop |
| `HostBits` | none (`ArchiveBase.HostBits` in `src/Xamarin.Installer.AndroidSDK/` is an unrelated C# property) | drop |
| `NdkLlvmTag` | none (the NDK toolchain OS tag is resolved elsewhere via `_NdkToolchainOSTag` in `androidsdk.targets`) | drop |
| `HostCpuCount` | only `Configuration.props:72` via `$(MakeConcurrency)` | drop |
## `$(MakeConcurrency)` audit
The only definition was `Configuration.props:72`. A repo-wide grep of `.targets`, `.props`, `.projitems`, `Makefile`, and `.mk` files found zero consumers of the MSBuild property. The `MakeConcurrency` hits under `build-tools/xaprepare/` were an unrelated C# `Context.MakeConcurrency` property.
**Result:** dropped the `MakeConcurrency` MSBuild property entirely (no `$([System.Environment]::ProcessorCount)` replacement needed) and removed the `$(MakeConcurrency)` bullet in `Documentation/building/configuration.md`.
## xaprepare integration audit (grep-confirmed, patched here)
| Location | Change |
| --- | --- |
| `build-tools/xaprepare/` (entire tree) | **deleted** — 86 tracked files |
| `Configuration.props` | dropped `<Import>` of the generated OS props, dropped `MakeConcurrency`, tidied the "between xaprepare and package creation tools" comment |
| `.gitignore` | dropped `Configuration.OperatingSystem.props` |
| `build-tools/scripts/PrepareWindows.targets` | removed `_XAPrepareExe`, `_XAPrepareStandardArgs`, `_BuildXAPrepare` target, and the `Exec dotnet $(_XAPrepareExe)` line. Repointed `Prepare` at `_InstallDotNet`. Kept the space-in-path guard, BootstrapTasks / workloads MSBuilds, and `PrepareJavaInterop` |
| `Makefile` | dropped `PREPARE_PROJECT`, `PREPARE_NET_FX`, `PREPARE_ARGS`, `PREPARE_MSBUILD_FLAGS`, `PREPARE_SCENARIO`, `PREPARE_CI_PR`, `PREPARE_CI`, `_PREPARE_CI_MODE_*`, `_PREPARE_ARGS`, and all their conditionals. Dropped the `dotnet run --project xaprepare.csproj` line from `prepare`. Deleted the `prepare-help` target |
| `build-tools/scripts/BuildEverything.mk` | `jenkins` no longer branches on `PREPARE_CI_PR`/`PREPARE_CI`; just `$(MAKE) prepare && $(MAKE) leeroy` |
| `.github/workflows/copilot-setup-steps.yml` | dropped now-unused `PREPARE_CI=1` |
| `build-tools/automation/azure-pipelines-apidocs.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-linux-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-macos-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/commercial-build.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/copy-extra-result-files.yaml` | dropped `**/Configuration.OperatingSystem.props` glob and the stale `Step_CopyExtraResultFilesForCI` xaprepare-step comment |
| `build-tools/automation/yaml-templates/generate-cgmanifest.yaml` | dropped the stale `Step_GenerateCGManifest` xaprepare-step comment |
| `build-tools/automation/yaml-templates/setup-jdk-variables.yaml` | renamed `$xaPrepareJdkPath` → `$xaJdkPath` for hygiene |
| `Documentation/workflow/HowToAddNewApiLevel.md` | rewrote the "Add New Platform" section to point at `<_PlatformPackage>` entries in `src/androidsdk/androidsdk.targets` instead of `AndroidToolchain.cs`; updated the `--android-sdk-platforms=all` recipe to `dotnet-local build src/androidsdk/androidsdk.csproj -p:AndroidSdkPlatforms=all` |
| `Documentation/building/unix/dependencies.md` | JDK-version link now points at `$(MicrosoftOpenJDKVersion)` in `/Configuration.props` instead of the deleted `Configurables.cs` |
| `Documentation/building/configuration.md` | removed the `$(MakeConcurrency)` bullet |
**Historical breadcrumb comments left as-is** (still accurate and useful for git-archaeology):
- `.github/skills/update-tpn/SKILL.md`

- `src/androidsdk/androidsdk.targets`
- `src/native/cmake-config/cmake-config.csproj`
- `src/workloads/workloads.csproj`
## Verification
- `build.cmd Prepare` — succeeded end-to-end on Windows (0 warnings, 0 errors). The trimmed `Prepare` target ran through `_InstallDotNet`, the space-in-path guard, `Xamarin.Android.BootstrapTasks.sln`, `src/workloads/workloads.csproj`, and `PrepareJavaInterop`.
- `dotnet build src\Xamarin.Android.Build.Tasks\Xamarin.Android.Build.Tasks.csproj -c Debug` — 0 errors (93 pre-existing warnings from `src/Mono.Android/` and generated MCW, unrelated to this change).
- Repo-wide grep for `HostOsName`, `HostOsFlavor`, `HostOsRelease`, `HostCpuCount`, `NdkLlvmTag`, and the MSBuild `MakeConcurrency` property — clean.
- Repo-wide grep for `xaprepare` — clean apart from the five intentional historical breadcrumb comments listed above.

Why
bin/configuration.mk exists only to persist CONFIGURATION=<value> between Unix make invocations. Removing it lets us delete the only meaningful contents of Step_GenerateFiles.Unix.cs, continuing the slow removal of xaprepare (see precedent: #11568, #11529).
What
  • Drop -include bin/configuration.mk from the top of Makefile. The CONFIGURATION ?= Debug fallback at the top of the file is unchanged.
  • Delete build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs entirely (it contained GeneratedConfigurationFile and a one-line AddUnixPostBuildSteps partial that registered it).
The partial void AddUnixPostBuildSteps (Context context, List<GeneratedFile> steps); declaration in Step_GenerateFiles.cs is intentionally left in place — partial methods without an implementation are legal in C#, and the call site becomes a zero-cost no-op. Step_GenerateFiles.Windows.cs implements a different partial (AddOSSpecificSteps) and is unaffected.
Why this is safe
CallerPre-change behaviorPost-change behavior
All CI YAML (build-linux-steps.yaml, build-macos-steps.yaml, commercial-build.yaml, azure-pipelines-apidocs.yaml)Passes CONFIGURATION=$(XA.Build.Configuration) on every make callSame — explicit value still wins
build.sh (make prepare && make jenkins && make pack-dotnet)First make prepare runs against an empty bin/, so the -include no-ops and ?= Debug takes effectIdentical — ?= Debug still takes effect
Fresh local checkout, bare make all?= Debug (no bin/configuration.mk yet)Same
Local dev who runs make prepare CONFIGURATION=Release then bare make allPersisted Release via bin/configuration.mkNow defaults back to Debug — must pass CONFIGURATION=Release on every invocation
That last case is the only behavior change. It was never documented as a contract anywhere in Documentation/ or README.md, and developers building Release locally should be passing the flag explicitly anyway.
Verification
  • git grep "configuration\.mk" and git grep "GeneratedConfigurationFile": zero matches after this change.
  • dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj: 0 warnings, 0 errors.
  • Rubber-duck review: no remaining Path.Combine(..., "configuration.mk") references, no Makefile target depends on bin/configuration.mk as a prerequisite, and the leftover partial-method declaration is benign.

[build] Remove unused bin/configuration.mk
1ad2d35
`bin/configuration.mk` existed only to persist `CONFIGURATION=<value>`
between Unix `make` invocations. CI passes `CONFIGURATION=...` explicitly
on every `make` call, and `build.sh` never sets it (so a fresh checkout
always hit the `CONFIGURATION ?= Debug` default anyway). Dropping the
include lets us delete the only meaningful contents of
`Step_GenerateFiles.Unix.cs`, continuing the slow removal of xaprepare.
- Drop `-include bin/configuration.mk` from the top of `Makefile`. The
`CONFIGURATION ?= Debug` fallback is unchanged.
- Delete `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs`
entirely. The `partial void AddUnixPostBuildSteps (...)` declaration in
`Step_GenerateFiles.cs` is left as a no-op (legal C#); the call site
becomes a zero-cost no-op. `Step_GenerateFiles.Windows.cs` implements a
different partial (`AddOSSpecificSteps`) and is unaffected.

Changes:
  • Removed -include bin/configuration.mk from the repo Makefile.
  • Deleted the Unix-only xaprepare generated-file step that produced bin/configuration.mk.
Reviewed changes
Copilot reviewed 2 out of 2 changed files in this pull request and generated 1 comment.
FileDescription
MakefileStops including bin/configuration.mk, leaving CONFIGURATION ?= Debug as the sole default mechanism.
build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.csRemoves the generator that created bin/configuration.mk and the Unix partial-step registration.

Drop now-dead AddUnixPostBuildSteps partial
5a770f4
After deleting `Step_GenerateFiles.Unix.cs`, the `partial void
AddUnixPostBuildSteps (...)` declaration and its call site in
`Step_GenerateFiles.cs` were no-ops. Remove them so the file no longer
references a vestige of the `bin/configuration.mk` generator.

[xaprepare] Check inMono.Android.Apis.projitems, remove generator (#…
63951b8
…11608)
`Mono.Android.Apis.projitems` was previously generated at prepare time by
`GeneratedMonoAndroidProjitemsFile` (in xaprepare) from the
`BuildAndroidPlatforms.AllPlatforms` list. Both had exactly one consumer
(each other), so check in the projitems as a source file and drop the
generator plumbing.
Changes:
* Add `src/Mono.Android/Mono.Android.Apis.projitems` — content matches
the generator's output byte-for-byte; only the header comment now
points at `Documentation/workflow/HowToAddNewApiLevel.md` instead of
declaring "GENERATED FILE".
* Repoint the 4 importers (`Mono.Android.targets` x2,
`create-installers.targets`, `create-android-api.csproj`,
`Xamarin.Android.Build.Tasks.targets`) at the new path and drop the
`Condition="Exists(...)"` guards — the file is always present now.
* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* [Xamarin.AndroidTools] Remove dead VS Mac / legacy code (#11607)
Context: after the `android-platform-support` repo was inlined here
(see c22cdcf), `src/Xamarin.AndroidTools/` carries a large amount of
code that was only used by old VS Mac / installer / debugger-host
workflows that are no longer part of the .NET for Android product. None
of these types have callers anywhere in this repo, in
`external/xamarin-android-tools/`, or in `external/Java.Interop/`.
Removed (13 files):
* `PublicationUtilities/PublishAndroidApplication.cs`
* `PublicationUtilities/PackageSigningTasks.cs`
* `PublicationUtilities/KeyManagement.cs`
* `PublicationUtilities/KeystoreEntry.cs`
* `Sessions/AndroidDeploySession.cs`
* `Sessions/AndroidConnectCommandSession.cs`
* `Sessions/AndroidCommandSession.cs`
* `Sessions/AndroidDeploymentException.cs`
* `Devices/AndroidPackageList.cs`
* `Devices/AndroidPackageListExtensions.cs`
* `Debugging/MonoDroidProcessMonitor.cs`
* `PlatformPackage.cs`
* `IProgressNotifier.cs`
* `AndroidSigningOptions.cs`
Moved (still needed by `ProcessUtils.cs`):
* `PublicationUtilities/AndroidSdkToolException.cs` ->
`AndroidSdkToolException.cs` (namespace unchanged)
Pruned from `Devices/AndroidDeviceExtensions.cs` (the methods only
referenced the just-deleted types and had no in-tree callers):
* `StartActivityWithCommandSession` (used `AndroidCommandSession`)
* `GetDeploySession`, `GetPackagesAsync`, `GetPackages` (used
`AndroidDeploySession` / `IProgressNotifier`)
* `InstallSharedRuntime*` and `InstallSharedPlatform*` overloads
that took `IProgressNotifier`
* `GetPackageRemotePath`/`GetPackageRemotePathAsync` (used
`AndroidDeploymentException`)
* `GetFastDevRemotePath`/`GetFastDevRemotePathAsync` and the inner
`FastDevRemotePathInfo` class (only consumer was
`GetPackageRemotePathAsync`)
Kept methods in `AndroidDeviceExtensions.cs` are the ones still used
by `Xamarin.Android.Build.Debugging.Tasks` (`EnsureProperties`,
`KillProcessAndWaitForExit`, `PushAndInstallPackageAsync`) and by
`DebuggingExtensions` (`SetFastDevPropertyFile`, `GetProcessIDAsync`,
`SetDebugPropertiesAsync`).
Also cleaned up:
* `Properties/Resources.resx` (English source): removed seven
`CreateKeyError_*` strings that only `KeyManagement.cs` used.
* `Properties/Resources.Designer.cs`: removed the seven matching
properties.
* `MonoDroidSdk.cs`: two `[Obsolete]` messages referenced the
now-deleted `PlatformPackage`; changed to `"Do not use."`.
Non-English `Resources.*.resx` and `Localize/loc/**/*.lcl` are left
alone per repo policy (auto-regenerated by OneLocBuild).
Build verified locally:
* `src/Xamarin.AndroidTools/Xamarin.AndroidTools.csproj`
* `src/Mono.AndroidTools/Mono.AndroidTools.csproj`
* `src/Xamarin.Android.Build.Debugging.Tasks/Xamarin.Android.Build.Debugging.Tasks.csproj`
* `src/Xamarin.Installer.AndroidSDK/Xamarin.Installer.AndroidSDK.csproj`
Net change: -4225 / +2 lines across 19 files.

* [NUnitLite] Add OneTimeSetUp/OneTimeTearDown attribute shims
NUnit 3.x renamed [TestFixtureSetUp]/[TestFixtureTearDown] to [OneTimeSetUp]/[OneTimeTearDown]. dotnet/java-interop#1437 migrated the Java.Interop test suite to the new names.
The bundled Xamarin.Android.NUnitLite (src-ThirdParty/NUnitLite/) only defines the legacy names. Add no-op subclasses for the new names so test source using [OneTimeSetUp]/[OneTimeTearDown] still compiles against bundled NUnitLite once the Java.Interop submodule is bumped past dotnet/java-interop#1437.
These shims become unnecessary once dotnet/android moves off bundled NUnitLite to stock NUnit (tracked in PR #11224).

@jonathanpeppers
[build] Remove Step_PrepareProps; fold values into eng/Versions.props (…
ee0392c
…#11613)
Continues the slow `xaprepare` removal. Recent precedent: #11568 (CopyExtraResultFilesForCI → YAML), #11580 (configuration.mk removal), #11529 (android-platform-support consolidation, which also dropped `Step_PrepareExternalGitDependencies`).
## What
`Step_PrepareProps` generated `external/Java.Interop/Configuration.Override.props` (inside the submodule) by substituting two placeholders into `build-tools/scripts/Configuration.Java.Interop.Override.in.props`. The substituted properties (`_XamarinAndroidCecilVersion`, `UtilityOutputFullPathCoreApps`, `XamarinAndroidToolsDirectory`) are now supplied directly via the checked-in static file `external/Java.Interop.override.props`, which Java.Interop's own `Directory.Build.props` already auto-imports via the parent-dir convention added in dotnet/java-interop#872.
The shared version values (`MonoCecilVersion`, `AndroidPackVersion`, `AndroidPackVersionSuffix`) move into `eng/Versions.props`. `Directory.Build.props` and `external/Java.Interop.override.props` both `<Import>` it. No duplicate-import sentinel is needed because every code path that imports `Configuration.props` has already loaded `Directory.Build.props` (either via MSBuild auto-load or via the explicit `<Import>` in `external/xamarin-android-tools.override.props`).
`MicrosoftAndroidSdkPackName` stays in `Configuration.props` (it is OS-conditioned, not version-shaped, so it doesn't belong in `Versions.props`). The same 3-line OS-conditioned block is mirrored privately in `external/Java.Interop.override.props` as `_MicrosoftAndroidSdkPackName`, used only to compute `UtilityOutputFullPathCoreApps` for the Java.Interop build.
Also dropped:
- `Configurables.Paths.InstallMSBuildDir` and its backing field — the only consumer was `Step_PrepareProps`.
- The dead `UtilityOutputFullPath` line in the old template — Java.Interop's `TargetFrameworkDependentValues.props` unconditionally routes it to `$(UtilityOutputFullPathCoreApps)` anyway, so it was a no-op.
Updated `build-tools/scripts/XAVersionInfo.targets` (the `GitBlame` for `<AndroidPackVersion>` now points at `eng/Versions.props`) and `Documentation/guides/HowToBranch.md` to reflect the moves.
## Why not just `<Import>` `Directory.Build.props` from the Java.Interop override?
That was the original idea. I prototyped it: importing dotnet/android's full props chain from `external/Java.Interop.override.props` flips `DotNetTargetFrameworkVersion` from `10.0` to `11.0` inside Java.Interop, and `dotnet restore Java.Interop.csproj` then fails with:
```
NETSDK1045: The current .NET SDK does not support targeting .NET 11.0
```
`xamarin-android-tools.override.props` gets away with the same trick only because its sole csproj sets `AndroidToolsDisableMultiTargeting=true`, which makes the TFM-clobber harmless. Java.Interop has no equivalent escape hatch.
`eng/Versions.props` is collision-free with Java.Interop (verified against the submodule sources — none of the existing entries collide), has no `<Import>` of its own, and is the safe minimal shared file.
## Verification
On Windows:
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj` — 0 warnings, 0 errors.
- From `src/Xamarin.Android.Build.Tasks/`: `dotnet msbuild --getProperty:MonoCecilVersion,AndroidPackVersion,AndroidPackVersionSuffix,MicrosoftAndroidSdkPackName,MicrosoftAndroidSdkOutDir` — values unchanged from baseline.
- From `external/Java.Interop/src/Java.Interop/`:
- `dotnet msbuild --getProperty:DotNetTargetFramework,_XamarinAndroidCecilVersion,UtilityOutputFullPathCoreApps` returns `net10.0`, `0.11.5`, the expected packs/tools path.
- `dotnet restore Java.Interop.csproj` succeeds (no `NETSDK1045`).

@jonathanpeppers
[build] Remove omnisharp.json generation from xaprepare (#11631)
58ccc1f
### Context
`Get_Omnisharp_Json` in `Step_GenerateFiles` substituted two placeholders into `build-tools/scripts/omnisharp.json.in` and wrote `omnisharp.json` at the repo root for OmniSharp / VS Code C# extension users. The generated file was always `.gitignore`d and **nothing in the repo, build, or CI consumes it** — it was purely a local-dev convenience.
Anyone who actually wants an `omnisharp.json` can keep their own local copy (it remains gitignored). Removing this generation slice is another small step in the slow xaprepare reduction, continuing the pattern from #11568, #11580, #11608, and #11613.
### Audit
Before this change `git grep -in "omnisharp"` returned five hits. After it returns only one — the unrelated MSBuild-context guard in `xaprepare.csproj` that prevents xaprepare's targets from importing under OmniSharp's MSBuild process:
```
build-tools/xaprepare/xaprepare/xaprepare.csproj:52:
<Import Project="xaprepare.targets" Condition=" $(MSBuildToolsPath.IndexOf('omnisharp')) < 0 " />
```
That guard is intentional and is **not** touched by this PR.
### Changes
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`: drop the `Get_Omnisharp_Json (context)` entry from the generated-files list and delete the `Get_Omnisharp_Json` method.
- Delete `build-tools/scripts/omnisharp.json.in`.
The shared properties used by the deleted method (`MicrosoftDotnetSdkInternalPackageVersion`, `DotNetPreviewPath`) are still referenced by `Step_InstallDotNetPreview` and `xaprepare.targets`, so they remain.
### Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` — 0 warnings, 0 errors.
- `git grep -in "omnisharp"` — returns only the unrelated `xaprepare.csproj` guard described above.
- No `Documentation/` references to omnisharp; no `.vscode/` folder in the repo.
- Diff: 3 files, 35 deletions, 0 additions.

[xaprepare] Check in Ndk.projitems, remove generator (#11733)
dc54c1c
Mirrors #11608 (which checked in `Mono.Android.Apis.projitems` the same way). See also #11568, #11580, #11613, #11631, #11657, #11658.
## What
`build-tools/scripts/Ndk.projitems.in` was a template with `@NDK_*@` placeholders that the `Get_Ndk_projitems` generator in xaprepare filled in from constants in `BuildAndroidPlatforms.cs`. Those substitution values only change on rare NDK bumps, so generating the file on every build adds no value.
This PR checks in the resolved file as a static `build-tools/scripts/Ndk.projitems` and removes the generator.
## Changes
- **Add** `build-tools/scripts/Ndk.projitems` — the static, checked-in file. Rather than hardcoding values, it sources them from the existing properties in `Configuration.props` (which is imported before `Ndk.targets`):
- `AndroidNdkVersion` → `$(_XAAndroidNdkRelease)`
- `AndroidNdkPkgRevision` → `$(_XAAndroidNdkPkgRevision)`
- the per-ABI `AndroidNdkApiLevel_*` → `$(AndroidMinimumDotNetApiLevel)`
So there is nothing to keep in sync on an NDK/API bump.
- **`build-tools/scripts/Ndk.targets`** — point `ProjitemsFile` at the new in-tree location (`$(MSBuildThisFileDirectory)Ndk.projitems`) instead of `bin/Build$(Configuration)/Ndk.projitems`.
- **Delete** `build-tools/scripts/Ndk.projitems.in`.
- **`Step_GenerateFiles.cs`** — remove the `Get_Ndk_projitems` method and its dispatch entry.
- **`Configurables.cs`** — update a doc comment reference from `Ndk.projitems.in` → `Ndk.projitems`.
### Simplifications (from review)
- **Collapsed the dead legacy/NET API-level split.** The legacy 32-bit minimum API level used to be lower than the .NET minimum, but they are identical now. Removed the two per-ABI properties that nothing references (`AndroidNdkApiLevel_Arm`, `AndroidNdkApiLevel_X86_Legacy`). The `arm64-v8a`/`x86_64` properties are kept because shipped targets (`Build.Tasks.targets`, `Common.props.in`, `NativeAOT.targets`) still consume them by name.
- **Removed the `ApiLevelNET` item metadata.** `ApiLevelNET` was the .NET (.NET 6+) Android minimum API level vs. the legacy Xamarin.Android/Mono `ApiLevel`; the two are identical now and this repo is .NET-only. Its only consumer was `src/native/common/libunwind/libunwind-xamarin.targets`, which now reads `ApiLevel`. Dropped `ApiLevelNET` from all four `AndroidSupportedTargetJitAbi` items.
The NDK constants in `BuildAndroidPlatforms.cs` are intentionally left untouched — they're still consumed by `Get_XABuildConfig_cs` and the cmake presets generator.
## Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 errors / 0 warnings.
- Evaluated the import chain via a standalone MSBuild harness (importing the real `Configuration.props`); it produces all four `AndroidSupportedTargetJitAbi` items with `ApiLevel`=24 and the expected `AndroidRID` metadata, matching prior generator output (NDK `28c` / pkg `28.2.13676358`).
- Audits clean: `git grep Ndk.projitems.in`, `git grep Ndk_projitems`, `git grep ApiLevelNET`, and the old `bin/Build$(Configuration)/Ndk.projitems` path all return 0 hits.

[xaprepare] Remove unused tool runners and helper classes (#11740)
185bf46
Many xaprepare provisioning steps have been removed over the past year (#11332, #11348, #11399, #11440, #11441, #11636 and follow-up cleanups in #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737). The supporting scaffolding around those steps was left behind. This PR removes the verified-dead pieces in two passes.
## Files removed (first pass — original audit)
| File | Justification |
| --- | --- |
| `Application/TestAssembly.cs` | Orphan test infra; only referenced by `TestAssemblyType.cs`. |
| `Application/TestAssemblyType.cs` | Only referenced by `TestAssembly.cs`. |
| `Application/StepWithDownloadProgress.cs` | No subclasses remain. |
| `Application/NDKTool.cs` | NDK provisioning moved to MSBuild in #11440. Last consumer was the also-dead `Configurables.NDKTools` collection (removed below). |
| `ToolRunners/SnRunner.cs` | Strong-naming tool runner; never instantiated. |
| `ToolRunners/SnRunner.OutputSink.cs` | Partial sibling of `SnRunner`. |
| `ToolRunners/CMakeRunner.cs` | Never instantiated. |
| `ToolRunners/CMakeRunner.OutputSink.cs` | Partial sibling of `CMakeRunner`. |
## Files removed (second pass — repo-wide re-audit)
| File | Justification |
| --- | --- |
| `ToolRunners/MakeRunner.Linux.cs` | Partial of `MakeRunner`; type never instantiated. |
| `ToolRunners/MakeRunner.MacOS.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.OutputSink.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MSBuildRunner.cs` | Never instantiated. |
| `ToolRunners/MSBuildRunner.OutputSink.cs` | Partial sibling of `MSBuildRunner`. |
| `ToolRunners/NinjaRunner.cs` | Never instantiated. |
| `ToolRunners/NinjaRunner.OutputSink.cs` | Partial sibling of `NinjaRunner`. |
| `Application/ScenarioNoStandardEndSteps.cs` | Abstract class with zero subclasses. |
## Cascading cleanup
- `ConfigAndData/Configurables.cs` — removed the dead `NDKTools` `List<NDKTool>` collection (lines 132–145). Rest of the file unchanged.
## Removed from initial deletion list after verification
- `Application/Extensions.DictionaryOfProgramVersionParser.cs` — initial name-only audit flagged it as dead, but its `Add` extension method is consumed via dictionary collection-initializer syntax in `Application/VersionFetchers.cs`. The consumer never references the static class by name, which is why the first audit missed it. The file stays.
- `Scenarios/Scenario_Required.cs` — looks unreferenced by static grep, but `Scenario` subclasses are reflectively discovered via the `[Scenario]` attribute in `Context.cs` (`Utilities.GetTypesWithCustomAttribute<ScenarioAttribute> ()`). Live. The file stays.
## Verification
- `git grep -n -w <TypeName>` for each deleted type now returns 0 real hits (only unrelated `"TestAssembly"` string literals in `tests/Microsoft.Android.Sdk.TrimmableTypeMap.Tests/` remain — those are assembly-name strings, not the C# type).
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 warnings, 0 errors.
## Deferred follow-up
The csproj conditionally excludes `*MacOS*` files from compilation when `HostOS != Darwin`, so static dead-code analysis from a Windows/Linux host can't see whether the macOS-only consumers are themselves live. These candidates need verification on a Mac host (or a build matrix) before deletion:
- `Application/PkgProgram.MacOS.cs`
- `Application/HomebrewProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
- `ConfigAndData/Dependencies/MacOS.cs`

[xaprepare] Move CMake file generation into a dedicated MSBuild proje…
5e9346d
…ct (#11760)
Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.
## What changes
Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:
* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.
Both are now generated by a new project:
* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.
### Why a dedicated project (not just a target in `native.targets`)
The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:
* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).
A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.
### Incremental correctness
`_GenerateCMakeFiles` declares fully-anchored `Inputs`:
* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)
so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)
### Cascading deletions in xaprepare
* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.
`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).
### What stays
The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.
## Verification
On Windows:
* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors
Incremental behaviour verified by walking through MSBuild diagnostic output:
* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.
The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.

[xaprepare] Remove vestigial OS dependency provisioning (#11803)
e89fded
### Context
After #11636 (dotnet provisioning step removed) and #11731 (test-deps scenarios removed), `Context.AutoProvision` is `false` by default everywhere except hand-run dev provisioning, which is no longer in use. The per-OS package lists are populated at `OS.Init()` time but `EnsureDependencies` is effectively a no-op:
- `OS.EnsureDependencies()` returns early when `AutoProvision` is false (the default),
- nothing else in the codebase reads from the `Program` derivatives' install/uninstall paths,
- the `BuildToolsInventory` writer remains driven only from `EssentialTools.MacOS.cs` (homebrew version detection).
The `OS.Init() / InitializeDependencies() / EnsureDependencies()` machinery on `OS.cs` itself is intentionally **left in place** here — that's a larger refactor for a follow-up PR. This PR only strips the now-vestigial package-list data and the program/runner classes that fed it.
### Files deleted (Phase F — macOS, 4 files)
- `Application/HomebrewProgram.MacOS.cs`
- `Application/PkgProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
### Files deleted (Phase G — Linux, 5 files)
- `Application/Program.Linux.cs` (`LinuxProgram` base — orphan after subclasses go)
- `Application/Program.ArchLinux.cs`
- `Application/Program.DebianLinux.cs`
- `Application/Program.FedoraLinux.cs`
- `Application/Program.GentooLinux.cs`
### Files deleted (Phase 3 — orphan)
- `Application/IBuildInventoryItem.cs` (only implementor was `HomebrewProgram`; `BuildToolsInventory` itself stays, populated directly by `EssentialTools.MacOS.cs`).
### Files reduced to empty stubs
`ConfigAndData/Dependencies/`:
- `MacOS.cs` — `InitializeDependencies()` no-op (was Homebrew formula list + git fallback).
- `Linux.Arch.cs` — class kept (referenced by `distroMap`); package list removed.
- `Linux.Fedora.cs` — same.
- `Linux.Gentoo.cs` — same.
- `Linux.DebianCommon.cs` — common Debian/Ubuntu package list removed; `Flavor = "Debian"` kept.
- `Linux.UbuntuCommon.cs` — `libtoolPackages` + `NeedLibtool` virtual + `InitOS` override removed (all dead).
- `Linux.Debian.cs` — all per-version package lists (`packages`, `packagesPre10`, `packagesPreTrixie`, `packagesTrixieAndLater`, `packages10AndNewerBuildBots`) removed; release/codename detection (`EnsureVersionInformation`, `DebianUnstableVersionMap`, `IsDebian10OrNewer`, etc.) preserved as conservative scope.
- `Linux.Ubuntu.cs` — `preCosmicPackages`, `cosmicPackages`, `preDiscoPackages` lists + `NeedLibtool` override removed; `UbuntuRelease` + `EnsureVersionInformation` preserved.
- `Linux.Mint.cs` — `NeedLibtool` override removed (the property is gone from the base).
`ConfigAndData/Dependencies/Windows.cs` was already a no-op stub — no edit.
### Verification
Orphan audit (each `git grep -nw <Type> -- 'build-tools/xaprepare/*'` reports **0 hits**):
- `HomebrewProgram`, `PkgProgram`, `BrewRunner`, `PkgutilRunner`
- `ArchLinuxProgram`, `DebianLinuxProgram`, `FedoraLinuxProgram`, `GentooLinuxProgram`, `LinuxProgram`
- `IBuildInventoryItem`
Build:
```
dotnet build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug
Build succeeded. 0 Warning(s) 0 Error(s)
```
### Out of scope (follow-up)
- Removing the abstract `OS.InitializeDependencies()` declaration and the surrounding `EnsureDependencies()` machinery from `OperatingSystems/OS.cs`.
- `VersionFetchers` / `ProgramVersionParser` / `RegexProgramVersionParser` / `SevenZipVersionParser` / `Extensions.DictionaryOfProgramVersionParser.cs` are kept — `Utilities.GetProgramVersion` still queries them from `Program.cs`, `ToolRunner.cs`, `EssentialTools.MacOS.cs`, and `OperatingSystems/MacOS.cs` (brew detection).
### Precedent
#11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740, #11760

[xaprepare] Move XABuildConfig generation to AndroidBuildConfig.dll (#…
788d363
…11826)
## Summary
Moves `XABuildConfig.cs` generation out of `xaprepare` and into a new strong-named class library at `src/AndroidBuildConfig/AndroidBuildConfig.csproj` that produces `AndroidBuildConfig.dll`.
This continues the incremental removal of `xaprepare`, following the precedent set by `cmake-config.csproj` (#11760) and the recent batch #11568, #11580, #11608, #11613, #11631, #11731, #11732, #11733, #11737, #11740, #11803, #11821, #11825.
It also fixes a long-standing wart: previously `XABuildConfig.cs` was `<Compile Include>`'d into three different assemblies (`Xamarin.Android.Build.Tasks`, `Xamarin.ProjectTools`, and `Xamarin.Android.Build.Tests`), so every test that mentioned `XABuildConfig` produced a `CS0436` "type conflicts with imported type" warning — about **22** of them.
Wrapping the type in its own assembly collapses it to a single definition that every consumer references normally. After this change `Xamarin.Android.Build.Tests` builds with **7** warnings (none for `XABuildConfig`).
## How it works
`src/AndroidBuildConfig/AndroidBuildConfig.csproj`:
- `Microsoft.NET.Sdk` / `netstandard2.0`, strong-named with `product.snk`.
- `ProjectReference`s `Xamarin.Android.Tools.AndroidSdk` (for the `AndroidTargetArch` enum used by the template).
- `<UsingTask>`s `ReplaceFileContents`, `GitCommitHash`, and `GitBranch` from `$(PrepTasksAssembly)`, all with `TaskFactory="TaskHostFactory" Runtime="NET"` per repo convention.
- The `_GenerateXABuildConfig` target runs `BeforeTargets="BeforeCompile;CoreCompile"`, computes every substitution from MSBuild properties already exposed by `Configuration.props` (NDK major/minor/micro via `$(_XAAndroidNdkPkgRevision.Split('.'))`, API levels via `Split`/`Contains`, full commit hash via `GitCommitHash.CommitHash`, branch via `GitBranch.Branch`), and writes the file to `$(IntermediateOutputPath)XABuildConfig.cs`. The `<Compile Include>` lives inside the target so it resolves at execution time, when `IntermediateOutputPath` is final.
- `XABuildConfig` is now `public static class` instead of `internal static class`.
The three consumer csprojs lose their `<Compile Include="…XABuildConfig.cs" />` and now have a normal `<ProjectReference Include="…AndroidBuildConfig.csproj" />` (no `ReferenceOutputAssembly="False"`).
`build-tools/installers/create-installers.targets` ships `AndroidBuildConfig.dll` + `.pdb` alongside `Xamarin.Android.Build.Tasks.dll`.
## xaprepare cleanup
Removed dead code that only existed to feed the old `Get_XABuildConfig_cs` step:
- `Step_GenerateFiles.Get_XABuildConfig_cs` and its `GetMajor` / `GetMinor` locals
- `BuildInfo`: `NDKRevision`, `NDKVersionMajor`, `NDKVersionMinor`, `NDKVersionMicro`, `NDKVersion`, `XACommitHash`, `XABranch`, `GatherGitInfo`, `DetermineXACommitInfo`, `cachedNdkVersion`
- `Context`: the `if (SelectedScenario.NeedsGitBuildInfo) { await BuildInfo.GatherGitInfo … }` block
- `Scenario.NeedsGitBuildInfo` (and the `NeedsGitBuildInfo = true;` setters in `Scenario_Standard` and `Scenario_Required`)
- `BuildAndroidPlatforms.cs` — entire file (only contained constants used by the deleted code)
- `Utilities.ParseAndroidPkgRevision`
- `GitRunner.GetTopCommitHash` and `GitRunner.GetBranchName` (class retained — still used by `BuildInfo.DetermineLastVersionChangeCommit`)
## Files
**Added**
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
**Renamed/moved**
- `build-tools/scripts/XABuildConfig.cs.in` → `src/AndroidBuildConfig/XABuildConfig.cs.in` (`static class` → `public static class`)
**Modified**
- `src/Xamarin.Android.Build.Tasks/Xamarin.Android.Build.Tasks.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.ProjectTools/Xamarin.ProjectTools.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Xamarin.Android.Build.Tests.csproj`
- `build-tools/installers/create-installers.targets`
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`
- `build-tools/xaprepare/xaprepare/Application/BuildInfo.cs`
- `build-tools/xaprepare/xaprepare/Application/Context.cs`
- `build-tools/xaprepare/xaprepare/Application/Scenario.cs`
- `build-tools/xaprepare/xaprepare/Application/Utilities.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Standard.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Required.cs`
- `build-tools/xaprepare/xaprepare/ToolRunners/GitRunner.cs`
- `build-tools/xaprepare/README.md`
**Deleted**
- `build-tools/xaprepare/xaprepare/ConfigAndData/BuildAndroidPlatforms.cs`
## Verification
- `AndroidBuildConfig.csproj`: 0 warnings, 0 errors.
- `Xamarin.Android.Build.Tasks.csproj`: 0 errors, 85 pre-existing unrelated warnings (none for `XABuildConfig`).
- `Xamarin.Android.Build.Tests.csproj`: 0 errors, **7** warnings — down from ~22; all `CS0436 XABuildConfig` conflicts eliminated.
- `xaprepare.csproj`: 0 warnings, 0 errors.
- Generated `XABuildConfig.cs` is semantically identical to the pre-change xaprepare output. The only token difference is the intentional `static class` → `public static class`; everything else (NDK split, API-level major/minor split, supported-ABIs semicolon list, full commit hash, branch name, etc.) matches the previous baseline byte-for-byte.

[xaprepare] Move cgmanifest.json generation from xaprepare to YAML (#…
c7c9458
…11825)
Continues the incremental removal of `xaprepare` by moving the
`cgmanifest.json` generator out of the C# step
`Step_GenerateCGManifest` and into a YAML `pwsh:` step that runs only
on CI.
The file is consumed exclusively by the Azure DevOps Component
Governance Detection task (auto-injected on internal pipelines by
`eng/common/core-templates/job/job.yml`). It is not consumed by any
in-repo build target, so generating it from the C# Prepare step is no
longer necessary.
We cannot drop the file outright: `eng/common` ships CG infrastructure
but it is not yet wired to auto-discover submodules in our pipelines,
so the explicit `cgmanifest.json` is still the source of truth.
Files:
* Added: `build-tools/automation/yaml-templates/generate-cgmanifest.yaml`
* Modified: `build-windows-steps.yaml`, `build-macos-steps.yaml`,
`build-linux-steps.yaml`, `commercial-build.yaml` (call the new
template after the Prepare/`make jenkins` step)
* Modified: `Scenario_Standard.cs` (drop registration)
* Modified: `GitRunner.cs` (remove now-unused `ConfigList` and
`SubmoduleStatus` methods)
* Deleted: `Step_GenerateCGManifest.cs`
Verification: byte-for-byte diff of the YAML-generated
`cgmanifest.json` against the previous C# output on Debug:
Baseline=3144 New=3144
Total byte differences: 0
Precedent PRs in this stream: #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803,
#11821.
### Simplify generate-cgmanifest.yaml using ConvertTo-Json
Replace the hand-rolled StringBuilder JSON emission with PowerShell's
`ConvertTo-Json`. The output is no longer byte-identical to the
previous C# output (2-space indent instead of 4, and slightly
different whitespace), but it is still valid JSON matching the
component-detection-manifest schema. The Azure DevOps Component
Governance Detection task parses the file, so formatting does not
matter.

[xaprepare] Delete redundant Windows JdkInfo.props generator (#11946)
e18dc17
On Windows, xaprepare's Step_GenerateFiles.Windows.cs writes
external/Java.Interop/bin/Build$(Configuration)/JdkInfo.props from
build-tools/xaprepare/xaprepare/Resources/JdkInfo.Windows.props.in.
But this file is immediately overwritten. The PrepareWindows.targets
Prepare flow runs, in order:
1. `dotnet xaprepare -a` — writes JdkInfo.props (this code).
2. `MSBuild Xamarin.Android.BootstrapTasks.sln` — does not read JdkInfo.props.
3. `MSBuild src/workloads/workloads.csproj` — does not read JdkInfo.props.
4. `CallTarget PrepareJavaInterop` → `dotnet build -t:Prepare Java.Interop.sln`
→ external/Java.Interop/build-tools/scripts/Prepare.targets → runs the
`JdkInfo` MSBuild task → overwrites JdkInfo.props with its own generated
content.
Nothing between step 1 and step 4 reads the file, and Java.Interop's Prepare
always regenerates it. Now that external/Java.Interop is in-tree, we can
safely delete the redundant write.
This is the smallest-diff removal:
* Delete Step_GenerateFiles.Windows.cs (the AddOSSpecificSteps partial).
* Delete Resources/JdkInfo.Windows.props.in.
* In Step_GenerateFiles.cs, drop the `partial void AddOSSpecificSteps`
declaration and collapse GetFilesToGenerate so `atBuildStart == false`
returns null. Ctor surface (atBuildStart, onlyRequired) is unchanged so
Scenario_Required.cs is unaffected.
* In Scenario_Standard.cs, remove the AddEndSteps override — the only
thing it did was schedule the now-empty Step_GenerateFiles(atBuildStart:
false).
Preserved (future slices will address these):
* Get_Configuration_OperatingSystem_props (D1).
* OperatingSystems/*.cs and Context.OS.* surface.
* PrepareWindows.targets, DotNet.targets, Java.Interop's Prepare.targets.
Verification:
* dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug
→ Build succeeded. 0 Warning(s). 0 Error(s).
* build.cmd -t:Prepare -c Debug (Windows, cold tree) → succeeds; the file
external/Java.Interop/bin/BuildDebug/JdkInfo.props exists.
* Compare-Object of the resulting JdkInfo.props before vs after this
change → byte-identical (1493 bytes, SHA256
DE59A8061B7657831788FFED7BC1DEECA442E9181605083A4553DE7AC8C003A1),
confirming Java.Interop's overwrite is what always ends up on disk.
* Grep audit under build-tools/xaprepare/: no remaining references to
Step_GenerateFiles.Windows, JdkInfo.Windows.props.in, or
AddOSSpecificSteps.

[xaprepare] Delete Configuration.OperatingSystem.props generator and …
be5272c
…xaprepare project (#11959)
Follow-up to #11956, which moved the JDK half of `Configuration.OperatingSystem.props` to Java.Interop's `JdkInfo.props`. The remaining NDK / OS-info half has zero real consumers, so this PR:
1. Deletes the last generator template (`Configuration.OperatingSystem.props.in`).
2. Cascades through `Step_GenerateFiles`, both `Scenario_*` classes (which now had zero steps), and every supporting `OperatingSystems/`, `Context.*OS.cs`, `EssentialTools.*`, `ToolRunners/*`, `Configurables.*`, `Application/*`, and `Main.cs` file that only existed to feed the scenarios.
3. Deletes the whole `build-tools/xaprepare/` project.
4. Patches every integration point (`Makefile`, `PrepareWindows.targets`, `BuildEverything.mk`, CI YAML, docs) so `build.cmd -t:Prepare` and `make prepare` still work end-to-end.
## `Configuration.OperatingSystem.props.in` placeholder audit
| Placeholder | Consumers outside the `.in` file | Action |
| --- | --- | --- |
| `HostOsName` | none | drop |
| `HostOsFlavor` | none | drop |
| `HostOsRelease` | none | drop |
| `HostBits` | none (`ArchiveBase.HostBits` in `src/Xamarin.Installer.AndroidSDK/` is an unrelated C# property) | drop |
| `NdkLlvmTag` | none (the NDK toolchain OS tag is resolved elsewhere via `_NdkToolchainOSTag` in `androidsdk.targets`) | drop |
| `HostCpuCount` | only `Configuration.props:72` via `$(MakeConcurrency)` | drop |
## `$(MakeConcurrency)` audit
The only definition was `Configuration.props:72`. A repo-wide grep of `.targets`, `.props`, `.projitems`, `Makefile`, and `.mk` files found zero consumers of the MSBuild property. The `MakeConcurrency` hits under `build-tools/xaprepare/` were an unrelated C# `Context.MakeConcurrency` property.
**Result:** dropped the `MakeConcurrency` MSBuild property entirely (no `$([System.Environment]::ProcessorCount)` replacement needed) and removed the `$(MakeConcurrency)` bullet in `Documentation/building/configuration.md`.
## xaprepare integration audit (grep-confirmed, patched here)
| Location | Change |
| --- | --- |
| `build-tools/xaprepare/` (entire tree) | **deleted** — 86 tracked files |
| `Configuration.props` | dropped `<Import>` of the generated OS props, dropped `MakeConcurrency`, tidied the "between xaprepare and package creation tools" comment |
| `.gitignore` | dropped `Configuration.OperatingSystem.props` |
| `build-tools/scripts/PrepareWindows.targets` | removed `_XAPrepareExe`, `_XAPrepareStandardArgs`, `_BuildXAPrepare` target, and the `Exec dotnet $(_XAPrepareExe)` line. Repointed `Prepare` at `_InstallDotNet`. Kept the space-in-path guard, BootstrapTasks / workloads MSBuilds, and `PrepareJavaInterop` |
| `Makefile` | dropped `PREPARE_PROJECT`, `PREPARE_NET_FX`, `PREPARE_ARGS`, `PREPARE_MSBUILD_FLAGS`, `PREPARE_SCENARIO`, `PREPARE_CI_PR`, `PREPARE_CI`, `_PREPARE_CI_MODE_*`, `_PREPARE_ARGS`, and all their conditionals. Dropped the `dotnet run --project xaprepare.csproj` line from `prepare`. Deleted the `prepare-help` target |
| `build-tools/scripts/BuildEverything.mk` | `jenkins` no longer branches on `PREPARE_CI_PR`/`PREPARE_CI`; just `$(MAKE) prepare && $(MAKE) leeroy` |
| `.github/workflows/copilot-setup-steps.yml` | dropped now-unused `PREPARE_CI=1` |
| `build-tools/automation/azure-pipelines-apidocs.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-linux-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-macos-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/commercial-build.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/copy-extra-result-files.yaml` | dropped `**/Configuration.OperatingSystem.props` glob and the stale `Step_CopyExtraResultFilesForCI` xaprepare-step comment |
| `build-tools/automation/yaml-templates/generate-cgmanifest.yaml` | dropped the stale `Step_GenerateCGManifest` xaprepare-step comment |
| `build-tools/automation/yaml-templates/setup-jdk-variables.yaml` | renamed `$xaPrepareJdkPath` → `$xaJdkPath` for hygiene |
| `Documentation/workflow/HowToAddNewApiLevel.md` | rewrote the "Add New Platform" section to point at `<_PlatformPackage>` entries in `src/androidsdk/androidsdk.targets` instead of `AndroidToolchain.cs`; updated the `--android-sdk-platforms=all` recipe to `dotnet-local build src/androidsdk/androidsdk.csproj -p:AndroidSdkPlatforms=all` |
| `Documentation/building/unix/dependencies.md` | JDK-version link now points at `$(MicrosoftOpenJDKVersion)` in `/Configuration.props` instead of the deleted `Configurables.cs` |
| `Documentation/building/configuration.md` | removed the `$(MakeConcurrency)` bullet |
**Historical breadcrumb comments left as-is** (still accurate and useful for git-archaeology):
- `.github/skills/update-tpn/SKILL.md`
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
- `src/androidsdk/androidsdk.targets`
- `src/native/cmake-config/cmake-config.csproj`
- `src/workloads/workloads.csproj`
## Verification
- `build.cmd Prepare` — succeeded end-to-end on Windows (0 warnings, 0 errors). The trimmed `Prepare` target ran through `_InstallDotNet`, the space-in-path guard, `Xamarin.Android.BootstrapTasks.sln`, `src/workloads/workloads.csproj`, and `PrepareJavaInterop`.
- `dotnet build src\Xamarin.Android.Build.Tasks\Xamarin.Android.Build.Tasks.csproj -c Debug` — 0 errors (93 pre-existing warnings from `src/Mono.Android/` and generated MCW, unrelated to this change).
- Repo-wide grep for `HostOsName`, `HostOsFlavor`, `HostOsRelease`, `HostCpuCount`, `NdkLlvmTag`, and the MSBuild `MakeConcurrency` property — clean.
- Repo-wide grep for `xaprepare` — clean apart from the five intentional historical breadcrumb comments listed above.

Why
bin/configuration.mk exists only to persist CONFIGURATION=<value> between Unix make invocations. Removing it lets us delete the only meaningful contents of Step_GenerateFiles.Unix.cs, continuing the slow removal of xaprepare (see precedent: #11568, #11529).
What
  • Drop -include bin/configuration.mk from the top of Makefile. The CONFIGURATION ?= Debug fallback at the top of the file is unchanged.
  • Delete build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs entirely (it contained GeneratedConfigurationFile and a one-line AddUnixPostBuildSteps partial that registered it).
The partial void AddUnixPostBuildSteps (Context context, List<GeneratedFile> steps); declaration in Step_GenerateFiles.cs is intentionally left in place — partial methods without an implementation are legal in C#, and the call site becomes a zero-cost no-op. Step_GenerateFiles.Windows.cs implements a different partial (AddOSSpecificSteps) and is unaffected.
Why this is safe
CallerPre-change behaviorPost-change behavior
All CI YAML (build-linux-steps.yaml, build-macos-steps.yaml, commercial-build.yaml, azure-pipelines-apidocs.yaml)Passes CONFIGURATION=$(XA.Build.Configuration) on every make callSame — explicit value still wins
build.sh (make prepare && make jenkins && make pack-dotnet)First make prepare runs against an empty bin/, so the -include no-ops and ?= Debug takes effectIdentical — ?= Debug still takes effect
Fresh local checkout, bare make all?= Debug (no bin/configuration.mk yet)Same
Local dev who runs make prepare CONFIGURATION=Release then bare make allPersisted Release via bin/configuration.mkNow defaults back to Debug — must pass CONFIGURATION=Release on every invocation
That last case is the only behavior change. It was never documented as a contract anywhere in Documentation/ or README.md, and developers building Release locally should be passing the flag explicitly anyway.
Verification
  • git grep "configuration\.mk" and git grep "GeneratedConfigurationFile": zero matches after this change.
  • dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj: 0 warnings, 0 errors.
  • Rubber-duck review: no remaining Path.Combine(..., "configuration.mk") references, no Makefile target depends on bin/configuration.mk as a prerequisite, and the leftover partial-method declaration is benign.

[build] Remove unused bin/configuration.mk
1ad2d35
`bin/configuration.mk` existed only to persist `CONFIGURATION=<value>`
between Unix `make` invocations. CI passes `CONFIGURATION=...` explicitly
on every `make` call, and `build.sh` never sets it (so a fresh checkout
always hit the `CONFIGURATION ?= Debug` default anyway). Dropping the
include lets us delete the only meaningful contents of
`Step_GenerateFiles.Unix.cs`, continuing the slow removal of xaprepare.
- Drop `-include bin/configuration.mk` from the top of `Makefile`. The
`CONFIGURATION ?= Debug` fallback is unchanged.
- Delete `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs`
entirely. The `partial void AddUnixPostBuildSteps (...)` declaration in
`Step_GenerateFiles.cs` is left as a no-op (legal C#); the call site
becomes a zero-cost no-op. `Step_GenerateFiles.Windows.cs` implements a
different partial (`AddOSSpecificSteps`) and is unaffected.

Pull request overview
Removes the Unix make configuration persistence mechanism (bin/configuration.mk) as part of the ongoing cleanup/removal of xaprepare, relying solely on the existing CONFIGURATION ?= Debug default and explicit CONFIGURATION=... passed to make.
Changes:
  • Removed -include bin/configuration.mk from the repo Makefile.
  • Deleted the Unix-only xaprepare generated-file step that produced bin/configuration.mk.
Reviewed changes
Copilot reviewed 2 out of 2 changed files in this pull request and generated 1 comment.
FileDescription
MakefileStops including bin/configuration.mk, leaving CONFIGURATION ?= Debug as the sole default mechanism.
build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.csRemoves the generator that created bin/configuration.mk and the Unix partial-step registration.

Drop now-dead AddUnixPostBuildSteps partial
5a770f4
After deleting `Step_GenerateFiles.Unix.cs`, the `partial void
AddUnixPostBuildSteps (...)` declaration and its call site in
`Step_GenerateFiles.cs` were no-ops. Remove them so the file no longer
references a vestige of the `bin/configuration.mk` generator.

[xaprepare] Check inMono.Android.Apis.projitems, remove generator (#…
63951b8
…11608)
`Mono.Android.Apis.projitems` was previously generated at prepare time by
`GeneratedMonoAndroidProjitemsFile` (in xaprepare) from the
`BuildAndroidPlatforms.AllPlatforms` list. Both had exactly one consumer
(each other), so check in the projitems as a source file and drop the
generator plumbing.
Changes:
* Add `src/Mono.Android/Mono.Android.Apis.projitems` — content matches
the generator's output byte-for-byte; only the header comment now
points at `Documentation/workflow/HowToAddNewApiLevel.md` instead of
declaring "GENERATED FILE".
* Repoint the 4 importers (`Mono.Android.targets` x2,
`create-installers.targets`, `create-android-api.csproj`,
`Xamarin.Android.Build.Tasks.targets`) at the new path and drop the
`Condition="Exists(...)"` guards — the file is always present now.
* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* [Xamarin.AndroidTools] Remove dead VS Mac / legacy code (#11607)
Context: after the `android-platform-support` repo was inlined here
(see c22cdcf), `src/Xamarin.AndroidTools/` carries a large amount of
code that was only used by old VS Mac / installer / debugger-host
workflows that are no longer part of the .NET for Android product. None
of these types have callers anywhere in this repo, in
`external/xamarin-android-tools/`, or in `external/Java.Interop/`.
Removed (13 files):
* `PublicationUtilities/PublishAndroidApplication.cs`
* `PublicationUtilities/PackageSigningTasks.cs`
* `PublicationUtilities/KeyManagement.cs`
* `PublicationUtilities/KeystoreEntry.cs`
* `Sessions/AndroidDeploySession.cs`
* `Sessions/AndroidConnectCommandSession.cs`
* `Sessions/AndroidCommandSession.cs`
* `Sessions/AndroidDeploymentException.cs`
* `Devices/AndroidPackageList.cs`
* `Devices/AndroidPackageListExtensions.cs`
* `Debugging/MonoDroidProcessMonitor.cs`
* `PlatformPackage.cs`
* `IProgressNotifier.cs`
* `AndroidSigningOptions.cs`
Moved (still needed by `ProcessUtils.cs`):
* `PublicationUtilities/AndroidSdkToolException.cs` ->
`AndroidSdkToolException.cs` (namespace unchanged)
Pruned from `Devices/AndroidDeviceExtensions.cs` (the methods only
referenced the just-deleted types and had no in-tree callers):
* `StartActivityWithCommandSession` (used `AndroidCommandSession`)
* `GetDeploySession`, `GetPackagesAsync`, `GetPackages` (used
`AndroidDeploySession` / `IProgressNotifier`)
* `InstallSharedRuntime*` and `InstallSharedPlatform*` overloads
that took `IProgressNotifier`
* `GetPackageRemotePath`/`GetPackageRemotePathAsync` (used
`AndroidDeploymentException`)
* `GetFastDevRemotePath`/`GetFastDevRemotePathAsync` and the inner
`FastDevRemotePathInfo` class (only consumer was
`GetPackageRemotePathAsync`)
Kept methods in `AndroidDeviceExtensions.cs` are the ones still used
by `Xamarin.Android.Build.Debugging.Tasks` (`EnsureProperties`,
`KillProcessAndWaitForExit`, `PushAndInstallPackageAsync`) and by
`DebuggingExtensions` (`SetFastDevPropertyFile`, `GetProcessIDAsync`,
`SetDebugPropertiesAsync`).
Also cleaned up:
* `Properties/Resources.resx` (English source): removed seven
`CreateKeyError_*` strings that only `KeyManagement.cs` used.
* `Properties/Resources.Designer.cs`: removed the seven matching
properties.
* `MonoDroidSdk.cs`: two `[Obsolete]` messages referenced the
now-deleted `PlatformPackage`; changed to `"Do not use."`.
Non-English `Resources.*.resx` and `Localize/loc/**/*.lcl` are left
alone per repo policy (auto-regenerated by OneLocBuild).
Build verified locally:
* `src/Xamarin.AndroidTools/Xamarin.AndroidTools.csproj`
* `src/Mono.AndroidTools/Mono.AndroidTools.csproj`
* `src/Xamarin.Android.Build.Debugging.Tasks/Xamarin.Android.Build.Debugging.Tasks.csproj`
* `src/Xamarin.Installer.AndroidSDK/Xamarin.Installer.AndroidSDK.csproj`

* [NUnitLite] Add OneTimeSetUp/OneTimeTearDown attribute shims
NUnit 3.x renamed [TestFixtureSetUp]/[TestFixtureTearDown] to [OneTimeSetUp]/[OneTimeTearDown]. dotnet/java-interop#1437 migrated the Java.Interop test suite to the new names.
The bundled Xamarin.Android.NUnitLite (src-ThirdParty/NUnitLite/) only defines the legacy names. Add no-op subclasses for the new names so test source using [OneTimeSetUp]/[OneTimeTearDown] still compiles against bundled NUnitLite once the Java.Interop submodule is bumped past dotnet/java-interop#1437.
These shims become unnecessary once dotnet/android moves off bundled NUnitLite to stock NUnit (tracked in PR #11224).

@jonathanpeppers
[build] Remove Step_PrepareProps; fold values into eng/Versions.props (…
ee0392c
…#11613)
Continues the slow `xaprepare` removal. Recent precedent: #11568 (CopyExtraResultFilesForCI → YAML), #11580 (configuration.mk removal), #11529 (android-platform-support consolidation, which also dropped `Step_PrepareExternalGitDependencies`).
## What
`Step_PrepareProps` generated `external/Java.Interop/Configuration.Override.props` (inside the submodule) by substituting two placeholders into `build-tools/scripts/Configuration.Java.Interop.Override.in.props`. The substituted properties (`_XamarinAndroidCecilVersion`, `UtilityOutputFullPathCoreApps`, `XamarinAndroidToolsDirectory`) are now supplied directly via the checked-in static file `external/Java.Interop.override.props`, which Java.Interop's own `Directory.Build.props` already auto-imports via the parent-dir convention added in dotnet/java-interop#872.
The shared version values (`MonoCecilVersion`, `AndroidPackVersion`, `AndroidPackVersionSuffix`) move into `eng/Versions.props`. `Directory.Build.props` and `external/Java.Interop.override.props` both `<Import>` it. No duplicate-import sentinel is needed because every code path that imports `Configuration.props` has already loaded `Directory.Build.props` (either via MSBuild auto-load or via the explicit `<Import>` in `external/xamarin-android-tools.override.props`).
`MicrosoftAndroidSdkPackName` stays in `Configuration.props` (it is OS-conditioned, not version-shaped, so it doesn't belong in `Versions.props`). The same 3-line OS-conditioned block is mirrored privately in `external/Java.Interop.override.props` as `_MicrosoftAndroidSdkPackName`, used only to compute `UtilityOutputFullPathCoreApps` for the Java.Interop build.
Also dropped:
- `Configurables.Paths.InstallMSBuildDir` and its backing field — the only consumer was `Step_PrepareProps`.
- The dead `UtilityOutputFullPath` line in the old template — Java.Interop's `TargetFrameworkDependentValues.props` unconditionally routes it to `$(UtilityOutputFullPathCoreApps)` anyway, so it was a no-op.
Updated `build-tools/scripts/XAVersionInfo.targets` (the `GitBlame` for `<AndroidPackVersion>` now points at `eng/Versions.props`) and `Documentation/guides/HowToBranch.md` to reflect the moves.
## Why not just `<Import>` `Directory.Build.props` from the Java.Interop override?
That was the original idea. I prototyped it: importing dotnet/android's full props chain from `external/Java.Interop.override.props` flips `DotNetTargetFrameworkVersion` from `10.0` to `11.0` inside Java.Interop, and `dotnet restore Java.Interop.csproj` then fails with:
```
NETSDK1045: The current .NET SDK does not support targeting .NET 11.0
```
`xamarin-android-tools.override.props` gets away with the same trick only because its sole csproj sets `AndroidToolsDisableMultiTargeting=true`, which makes the TFM-clobber harmless. Java.Interop has no equivalent escape hatch.
`eng/Versions.props` is collision-free with Java.Interop (verified against the submodule sources — none of the existing entries collide), has no `<Import>` of its own, and is the safe minimal shared file.
## Verification
On Windows:
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj` — 0 warnings, 0 errors.
- From `src/Xamarin.Android.Build.Tasks/`: `dotnet msbuild --getProperty:MonoCecilVersion,AndroidPackVersion,AndroidPackVersionSuffix,MicrosoftAndroidSdkPackName,MicrosoftAndroidSdkOutDir` — values unchanged from baseline.
- From `external/Java.Interop/src/Java.Interop/`:
- `dotnet msbuild --getProperty:DotNetTargetFramework,_XamarinAndroidCecilVersion,UtilityOutputFullPathCoreApps` returns `net10.0`, `0.11.5`, the expected packs/tools path.
- `dotnet restore Java.Interop.csproj` succeeds (no `NETSDK1045`).

[build] Remove omnisharp.json generation from xaprepare (#11631)
58ccc1f
### Context
`Get_Omnisharp_Json` in `Step_GenerateFiles` substituted two placeholders into `build-tools/scripts/omnisharp.json.in` and wrote `omnisharp.json` at the repo root for OmniSharp / VS Code C# extension users. The generated file was always `.gitignore`d and **nothing in the repo, build, or CI consumes it** — it was purely a local-dev convenience.
Anyone who actually wants an `omnisharp.json` can keep their own local copy (it remains gitignored). Removing this generation slice is another small step in the slow xaprepare reduction, continuing the pattern from #11568, #11580, #11608, and #11613.
### Audit
Before this change `git grep -in "omnisharp"` returned five hits. After it returns only one — the unrelated MSBuild-context guard in `xaprepare.csproj` that prevents xaprepare's targets from importing under OmniSharp's MSBuild process:
```
build-tools/xaprepare/xaprepare/xaprepare.csproj:52:
<Import Project="xaprepare.targets" Condition=" $(MSBuildToolsPath.IndexOf('omnisharp')) < 0 " />
```
That guard is intentional and is **not** touched by this PR.
### Changes
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`: drop the `Get_Omnisharp_Json (context)` entry from the generated-files list and delete the `Get_Omnisharp_Json` method.
- Delete `build-tools/scripts/omnisharp.json.in`.
The shared properties used by the deleted method (`MicrosoftDotnetSdkInternalPackageVersion`, `DotNetPreviewPath`) are still referenced by `Step_InstallDotNetPreview` and `xaprepare.targets`, so they remain.
### Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` — 0 warnings, 0 errors.
- `git grep -in "omnisharp"` — returns only the unrelated `xaprepare.csproj` guard described above.
- No `Documentation/` references to omnisharp; no `.vscode/` folder in the repo.
- Diff: 3 files, 35 deletions, 0 additions.

[xaprepare] Check in Ndk.projitems, remove generator (#11733)
dc54c1c
Mirrors #11608 (which checked in `Mono.Android.Apis.projitems` the same way). See also #11568, #11580, #11613, #11631, #11657, #11658.
## What
`build-tools/scripts/Ndk.projitems.in` was a template with `@NDK_*@` placeholders that the `Get_Ndk_projitems` generator in xaprepare filled in from constants in `BuildAndroidPlatforms.cs`. Those substitution values only change on rare NDK bumps, so generating the file on every build adds no value.
This PR checks in the resolved file as a static `build-tools/scripts/Ndk.projitems` and removes the generator.
## Changes
- **Add** `build-tools/scripts/Ndk.projitems` — the static, checked-in file. Rather than hardcoding values, it sources them from the existing properties in `Configuration.props` (which is imported before `Ndk.targets`):
- `AndroidNdkVersion` → `$(_XAAndroidNdkRelease)`
- `AndroidNdkPkgRevision` → `$(_XAAndroidNdkPkgRevision)`
- the per-ABI `AndroidNdkApiLevel_*` → `$(AndroidMinimumDotNetApiLevel)`
So there is nothing to keep in sync on an NDK/API bump.
- **`build-tools/scripts/Ndk.targets`** — point `ProjitemsFile` at the new in-tree location (`$(MSBuildThisFileDirectory)Ndk.projitems`) instead of `bin/Build$(Configuration)/Ndk.projitems`.
- **Delete** `build-tools/scripts/Ndk.projitems.in`.
- **`Step_GenerateFiles.cs`** — remove the `Get_Ndk_projitems` method and its dispatch entry.
- **`Configurables.cs`** — update a doc comment reference from `Ndk.projitems.in` → `Ndk.projitems`.
### Simplifications (from review)
- **Collapsed the dead legacy/NET API-level split.** The legacy 32-bit minimum API level used to be lower than the .NET minimum, but they are identical now. Removed the two per-ABI properties that nothing references (`AndroidNdkApiLevel_Arm`, `AndroidNdkApiLevel_X86_Legacy`). The `arm64-v8a`/`x86_64` properties are kept because shipped targets (`Build.Tasks.targets`, `Common.props.in`, `NativeAOT.targets`) still consume them by name.
- **Removed the `ApiLevelNET` item metadata.** `ApiLevelNET` was the .NET (.NET 6+) Android minimum API level vs. the legacy Xamarin.Android/Mono `ApiLevel`; the two are identical now and this repo is .NET-only. Its only consumer was `src/native/common/libunwind/libunwind-xamarin.targets`, which now reads `ApiLevel`. Dropped `ApiLevelNET` from all four `AndroidSupportedTargetJitAbi` items.
The NDK constants in `BuildAndroidPlatforms.cs` are intentionally left untouched — they're still consumed by `Get_XABuildConfig_cs` and the cmake presets generator.
## Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 errors / 0 warnings.
- Evaluated the import chain via a standalone MSBuild harness (importing the real `Configuration.props`); it produces all four `AndroidSupportedTargetJitAbi` items with `ApiLevel`=24 and the expected `AndroidRID` metadata, matching prior generator output (NDK `28c` / pkg `28.2.13676358`).
- Audits clean: `git grep Ndk.projitems.in`, `git grep Ndk_projitems`, `git grep ApiLevelNET`, and the old `bin/Build$(Configuration)/Ndk.projitems` path all return 0 hits.

[xaprepare] Remove unused tool runners and helper classes (#11740)
185bf46
Many xaprepare provisioning steps have been removed over the past year (#11332, #11348, #11399, #11440, #11441, #11636 and follow-up cleanups in #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737). The supporting scaffolding around those steps was left behind. This PR removes the verified-dead pieces in two passes.
## Files removed (first pass — original audit)
| File | Justification |
| --- | --- |
| `Application/TestAssembly.cs` | Orphan test infra; only referenced by `TestAssemblyType.cs`. |
| `Application/TestAssemblyType.cs` | Only referenced by `TestAssembly.cs`. |
| `Application/StepWithDownloadProgress.cs` | No subclasses remain. |
| `Application/NDKTool.cs` | NDK provisioning moved to MSBuild in #11440. Last consumer was the also-dead `Configurables.NDKTools` collection (removed below). |
| `ToolRunners/SnRunner.cs` | Strong-naming tool runner; never instantiated. |
| `ToolRunners/SnRunner.OutputSink.cs` | Partial sibling of `SnRunner`. |
| `ToolRunners/CMakeRunner.cs` | Never instantiated. |
| `ToolRunners/CMakeRunner.OutputSink.cs` | Partial sibling of `CMakeRunner`. |
## Files removed (second pass — repo-wide re-audit)
| File | Justification |
| --- | --- |
| `ToolRunners/MakeRunner.Linux.cs` | Partial of `MakeRunner`; type never instantiated. |
| `ToolRunners/MakeRunner.MacOS.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.OutputSink.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MSBuildRunner.cs` | Never instantiated. |
| `ToolRunners/MSBuildRunner.OutputSink.cs` | Partial sibling of `MSBuildRunner`. |
| `ToolRunners/NinjaRunner.cs` | Never instantiated. |
| `ToolRunners/NinjaRunner.OutputSink.cs` | Partial sibling of `NinjaRunner`. |
| `Application/ScenarioNoStandardEndSteps.cs` | Abstract class with zero subclasses. |
## Cascading cleanup
- `ConfigAndData/Configurables.cs` — removed the dead `NDKTools` `List<NDKTool>` collection (lines 132–145). Rest of the file unchanged.
## Removed from initial deletion list after verification
- `Application/Extensions.DictionaryOfProgramVersionParser.cs` — initial name-only audit flagged it as dead, but its `Add` extension method is consumed via dictionary collection-initializer syntax in `Application/VersionFetchers.cs`. The consumer never references the static class by name, which is why the first audit missed it. The file stays.
- `Scenarios/Scenario_Required.cs` — looks unreferenced by static grep, but `Scenario` subclasses are reflectively discovered via the `[Scenario]` attribute in `Context.cs` (`Utilities.GetTypesWithCustomAttribute<ScenarioAttribute> ()`). Live. The file stays.
## Verification
- `git grep -n -w <TypeName>` for each deleted type now returns 0 real hits (only unrelated `"TestAssembly"` string literals in `tests/Microsoft.Android.Sdk.TrimmableTypeMap.Tests/` remain — those are assembly-name strings, not the C# type).
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 warnings, 0 errors.
## Deferred follow-up
The csproj conditionally excludes `*MacOS*` files from compilation when `HostOS != Darwin`, so static dead-code analysis from a Windows/Linux host can't see whether the macOS-only consumers are themselves live. These candidates need verification on a Mac host (or a build matrix) before deletion:
- `Application/PkgProgram.MacOS.cs`
- `Application/HomebrewProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
- `ConfigAndData/Dependencies/MacOS.cs`

[xaprepare] Move CMake file generation into a dedicated MSBuild proje…
5e9346d
…ct (#11760)
Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.
## What changes
Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:
* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.
Both are now generated by a new project:
* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.
### Why a dedicated project (not just a target in `native.targets`)
The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:
* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).
A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.
### Incremental correctness
`_GenerateCMakeFiles` declares fully-anchored `Inputs`:
* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)
so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)
### Cascading deletions in xaprepare
* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.
`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).
### What stays
The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.
## Verification
On Windows:
* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors
Incremental behaviour verified by walking through MSBuild diagnostic output:
* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.
The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.

[xaprepare] Remove vestigial OS dependency provisioning (#11803)
e89fded
### Context
After #11636 (dotnet provisioning step removed) and #11731 (test-deps scenarios removed), `Context.AutoProvision` is `false` by default everywhere except hand-run dev provisioning, which is no longer in use. The per-OS package lists are populated at `OS.Init()` time but `EnsureDependencies` is effectively a no-op:
- `OS.EnsureDependencies()` returns early when `AutoProvision` is false (the default),
- nothing else in the codebase reads from the `Program` derivatives' install/uninstall paths,
- the `BuildToolsInventory` writer remains driven only from `EssentialTools.MacOS.cs` (homebrew version detection).
The `OS.Init() / InitializeDependencies() / EnsureDependencies()` machinery on `OS.cs` itself is intentionally **left in place** here — that's a larger refactor for a follow-up PR. This PR only strips the now-vestigial package-list data and the program/runner classes that fed it.
### Files deleted (Phase F — macOS, 4 files)
- `Application/HomebrewProgram.MacOS.cs`
- `Application/PkgProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
### Files deleted (Phase G — Linux, 5 files)
- `Application/Program.Linux.cs` (`LinuxProgram` base — orphan after subclasses go)
- `Application/Program.ArchLinux.cs`
- `Application/Program.DebianLinux.cs`
- `Application/Program.FedoraLinux.cs`
- `Application/Program.GentooLinux.cs`
### Files deleted (Phase 3 — orphan)
- `Application/IBuildInventoryItem.cs` (only implementor was `HomebrewProgram`; `BuildToolsInventory` itself stays, populated directly by `EssentialTools.MacOS.cs`).
### Files reduced to empty stubs
`ConfigAndData/Dependencies/`:
- `MacOS.cs` — `InitializeDependencies()` no-op (was Homebrew formula list + git fallback).
- `Linux.Arch.cs` — class kept (referenced by `distroMap`); package list removed.
- `Linux.Fedora.cs` — same.
- `Linux.Gentoo.cs` — same.
- `Linux.DebianCommon.cs` — common Debian/Ubuntu package list removed; `Flavor = "Debian"` kept.
- `Linux.UbuntuCommon.cs` — `libtoolPackages` + `NeedLibtool` virtual + `InitOS` override removed (all dead).
- `Linux.Debian.cs` — all per-version package lists (`packages`, `packagesPre10`, `packagesPreTrixie`, `packagesTrixieAndLater`, `packages10AndNewerBuildBots`) removed; release/codename detection (`EnsureVersionInformation`, `DebianUnstableVersionMap`, `IsDebian10OrNewer`, etc.) preserved as conservative scope.
- `Linux.Ubuntu.cs` — `preCosmicPackages`, `cosmicPackages`, `preDiscoPackages` lists + `NeedLibtool` override removed; `UbuntuRelease` + `EnsureVersionInformation` preserved.
- `Linux.Mint.cs` — `NeedLibtool` override removed (the property is gone from the base).
`ConfigAndData/Dependencies/Windows.cs` was already a no-op stub — no edit.
### Verification
Orphan audit (each `git grep -nw <Type> -- 'build-tools/xaprepare/*'` reports **0 hits**):
- `HomebrewProgram`, `PkgProgram`, `BrewRunner`, `PkgutilRunner`
- `ArchLinuxProgram`, `DebianLinuxProgram`, `FedoraLinuxProgram`, `GentooLinuxProgram`, `LinuxProgram`
- `IBuildInventoryItem`
Build:
```
dotnet build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug
Build succeeded. 0 Warning(s) 0 Error(s)
```
### Out of scope (follow-up)
- Removing the abstract `OS.InitializeDependencies()` declaration and the surrounding `EnsureDependencies()` machinery from `OperatingSystems/OS.cs`.
- `VersionFetchers` / `ProgramVersionParser` / `RegexProgramVersionParser` / `SevenZipVersionParser` / `Extensions.DictionaryOfProgramVersionParser.cs` are kept — `Utilities.GetProgramVersion` still queries them from `Program.cs`, `ToolRunner.cs`, `EssentialTools.MacOS.cs`, and `OperatingSystems/MacOS.cs` (brew detection).
### Precedent
#11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740, #11760

[xaprepare] Move XABuildConfig generation to AndroidBuildConfig.dll (#…
788d363
…11826)
## Summary
Moves `XABuildConfig.cs` generation out of `xaprepare` and into a new strong-named class library at `src/AndroidBuildConfig/AndroidBuildConfig.csproj` that produces `AndroidBuildConfig.dll`.
This continues the incremental removal of `xaprepare`, following the precedent set by `cmake-config.csproj` (#11760) and the recent batch #11568, #11580, #11608, #11613, #11631, #11731, #11732, #11733, #11737, #11740, #11803, #11821, #11825.
It also fixes a long-standing wart: previously `XABuildConfig.cs` was `<Compile Include>`'d into three different assemblies (`Xamarin.Android.Build.Tasks`, `Xamarin.ProjectTools`, and `Xamarin.Android.Build.Tests`), so every test that mentioned `XABuildConfig` produced a `CS0436` "type conflicts with imported type" warning — about **22** of them.
Wrapping the type in its own assembly collapses it to a single definition that every consumer references normally. After this change `Xamarin.Android.Build.Tests` builds with **7** warnings (none for `XABuildConfig`).
## How it works
`src/AndroidBuildConfig/AndroidBuildConfig.csproj`:
- `Microsoft.NET.Sdk` / `netstandard2.0`, strong-named with `product.snk`.
- `ProjectReference`s `Xamarin.Android.Tools.AndroidSdk` (for the `AndroidTargetArch` enum used by the template).
- `<UsingTask>`s `ReplaceFileContents`, `GitCommitHash`, and `GitBranch` from `$(PrepTasksAssembly)`, all with `TaskFactory="TaskHostFactory" Runtime="NET"` per repo convention.
- The `_GenerateXABuildConfig` target runs `BeforeTargets="BeforeCompile;CoreCompile"`, computes every substitution from MSBuild properties already exposed by `Configuration.props` (NDK major/minor/micro via `$(_XAAndroidNdkPkgRevision.Split('.'))`, API levels via `Split`/`Contains`, full commit hash via `GitCommitHash.CommitHash`, branch via `GitBranch.Branch`), and writes the file to `$(IntermediateOutputPath)XABuildConfig.cs`. The `<Compile Include>` lives inside the target so it resolves at execution time, when `IntermediateOutputPath` is final.
- `XABuildConfig` is now `public static class` instead of `internal static class`.
The three consumer csprojs lose their `<Compile Include="…XABuildConfig.cs" />` and now have a normal `<ProjectReference Include="…AndroidBuildConfig.csproj" />` (no `ReferenceOutputAssembly="False"`).
`build-tools/installers/create-installers.targets` ships `AndroidBuildConfig.dll` + `.pdb` alongside `Xamarin.Android.Build.Tasks.dll`.
## xaprepare cleanup
Removed dead code that only existed to feed the old `Get_XABuildConfig_cs` step:
- `Step_GenerateFiles.Get_XABuildConfig_cs` and its `GetMajor` / `GetMinor` locals
- `BuildInfo`: `NDKRevision`, `NDKVersionMajor`, `NDKVersionMinor`, `NDKVersionMicro`, `NDKVersion`, `XACommitHash`, `XABranch`, `GatherGitInfo`, `DetermineXACommitInfo`, `cachedNdkVersion`
- `Context`: the `if (SelectedScenario.NeedsGitBuildInfo) { await BuildInfo.GatherGitInfo … }` block
- `Scenario.NeedsGitBuildInfo` (and the `NeedsGitBuildInfo = true;` setters in `Scenario_Standard` and `Scenario_Required`)
- `BuildAndroidPlatforms.cs` — entire file (only contained constants used by the deleted code)
- `Utilities.ParseAndroidPkgRevision`
- `GitRunner.GetTopCommitHash` and `GitRunner.GetBranchName` (class retained — still used by `BuildInfo.DetermineLastVersionChangeCommit`)
## Files
**Added**
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
**Renamed/moved**
- `build-tools/scripts/XABuildConfig.cs.in` → `src/AndroidBuildConfig/XABuildConfig.cs.in` (`static class` → `public static class`)
**Modified**
- `src/Xamarin.Android.Build.Tasks/Xamarin.Android.Build.Tasks.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.ProjectTools/Xamarin.ProjectTools.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Xamarin.Android.Build.Tests.csproj`
- `build-tools/installers/create-installers.targets`
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`
- `build-tools/xaprepare/xaprepare/Application/BuildInfo.cs`
- `build-tools/xaprepare/xaprepare/Application/Context.cs`
- `build-tools/xaprepare/xaprepare/Application/Scenario.cs`
- `build-tools/xaprepare/xaprepare/Application/Utilities.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Standard.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Required.cs`
- `build-tools/xaprepare/xaprepare/ToolRunners/GitRunner.cs`
- `build-tools/xaprepare/README.md`
**Deleted**
- `build-tools/xaprepare/xaprepare/ConfigAndData/BuildAndroidPlatforms.cs`
## Verification
- `AndroidBuildConfig.csproj`: 0 warnings, 0 errors.
- `Xamarin.Android.Build.Tasks.csproj`: 0 errors, 85 pre-existing unrelated warnings (none for `XABuildConfig`).
- `Xamarin.Android.Build.Tests.csproj`: 0 errors, **7** warnings — down from ~22; all `CS0436 XABuildConfig` conflicts eliminated.
- `xaprepare.csproj`: 0 warnings, 0 errors.
- Generated `XABuildConfig.cs` is semantically identical to the pre-change xaprepare output. The only token difference is the intentional `static class` → `public static class`; everything else (NDK split, API-level major/minor split, supported-ABIs semicolon list, full commit hash, branch name, etc.) matches the previous baseline byte-for-byte.

[xaprepare] Move cgmanifest.json generation from xaprepare to YAML (#…
c7c9458
…11825)
Continues the incremental removal of `xaprepare` by moving the
`cgmanifest.json` generator out of the C# step
`Step_GenerateCGManifest` and into a YAML `pwsh:` step that runs only
on CI.
The file is consumed exclusively by the Azure DevOps Component
Governance Detection task (auto-injected on internal pipelines by
`eng/common/core-templates/job/job.yml`). It is not consumed by any
in-repo build target, so generating it from the C# Prepare step is no
longer necessary.
We cannot drop the file outright: `eng/common` ships CG infrastructure
but it is not yet wired to auto-discover submodules in our pipelines,
so the explicit `cgmanifest.json` is still the source of truth.
Files:
* Added: `build-tools/automation/yaml-templates/generate-cgmanifest.yaml`
* Modified: `build-windows-steps.yaml`, `build-macos-steps.yaml`,
`build-linux-steps.yaml`, `commercial-build.yaml` (call the new
template after the Prepare/`make jenkins` step)
* Modified: `Scenario_Standard.cs` (drop registration)
* Modified: `GitRunner.cs` (remove now-unused `ConfigList` and
`SubmoduleStatus` methods)
* Deleted: `Step_GenerateCGManifest.cs`
Verification: byte-for-byte diff of the YAML-generated
`cgmanifest.json` against the previous C# output on Debug:
Baseline=3144 New=3144
Total byte differences: 0
Precedent PRs in this stream: #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803,
#11821.
### Simplify generate-cgmanifest.yaml using ConvertTo-Json
Replace the hand-rolled StringBuilder JSON emission with PowerShell's
`ConvertTo-Json`. The output is no longer byte-identical to the
previous C# output (2-space indent instead of 4, and slightly
different whitespace), but it is still valid JSON matching the
component-detection-manifest schema. The Azure DevOps Component
Governance Detection task parses the file, so formatting does not
matter.

[xaprepare] Delete redundant Windows JdkInfo.props generator (#11946)
e18dc17
On Windows, xaprepare's Step_GenerateFiles.Windows.cs writes
external/Java.Interop/bin/Build$(Configuration)/JdkInfo.props from
build-tools/xaprepare/xaprepare/Resources/JdkInfo.Windows.props.in.
But this file is immediately overwritten. The PrepareWindows.targets
Prepare flow runs, in order:
1. `dotnet xaprepare -a` — writes JdkInfo.props (this code).
2. `MSBuild Xamarin.Android.BootstrapTasks.sln` — does not read JdkInfo.props.
3. `MSBuild src/workloads/workloads.csproj` — does not read JdkInfo.props.
4. `CallTarget PrepareJavaInterop` → `dotnet build -t:Prepare Java.Interop.sln`
→ external/Java.Interop/build-tools/scripts/Prepare.targets → runs the
`JdkInfo` MSBuild task → overwrites JdkInfo.props with its own generated
content.
Nothing between step 1 and step 4 reads the file, and Java.Interop's Prepare
always regenerates it. Now that external/Java.Interop is in-tree, we can
safely delete the redundant write.
This is the smallest-diff removal:
* Delete Step_GenerateFiles.Windows.cs (the AddOSSpecificSteps partial).
* Delete Resources/JdkInfo.Windows.props.in.
* In Step_GenerateFiles.cs, drop the `partial void AddOSSpecificSteps`
declaration and collapse GetFilesToGenerate so `atBuildStart == false`
returns null. Ctor surface (atBuildStart, onlyRequired) is unchanged so
Scenario_Required.cs is unaffected.
* In Scenario_Standard.cs, remove the AddEndSteps override — the only
thing it did was schedule the now-empty Step_GenerateFiles(atBuildStart:
false).
Preserved (future slices will address these):
* Get_Configuration_OperatingSystem_props (D1).
* OperatingSystems/*.cs and Context.OS.* surface.
* PrepareWindows.targets, DotNet.targets, Java.Interop's Prepare.targets.
Verification:
* dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug
→ Build succeeded. 0 Warning(s). 0 Error(s).
* build.cmd -t:Prepare -c Debug (Windows, cold tree) → succeeds; the file
external/Java.Interop/bin/BuildDebug/JdkInfo.props exists.
* Compare-Object of the resulting JdkInfo.props before vs after this
change → byte-identical (1493 bytes, SHA256
DE59A8061B7657831788FFED7BC1DEECA442E9181605083A4553DE7AC8C003A1),
confirming Java.Interop's overwrite is what always ends up on disk.
* Grep audit under build-tools/xaprepare/: no remaining references to
Step_GenerateFiles.Windows, JdkInfo.Windows.props.in, or
AddOSSpecificSteps.

[xaprepare] Delete Configuration.OperatingSystem.props generator and …
be5272c
…xaprepare project (#11959)
Follow-up to #11956, which moved the JDK half of `Configuration.OperatingSystem.props` to Java.Interop's `JdkInfo.props`. The remaining NDK / OS-info half has zero real consumers, so this PR:
1. Deletes the last generator template (`Configuration.OperatingSystem.props.in`).
2. Cascades through `Step_GenerateFiles`, both `Scenario_*` classes (which now had zero steps), and every supporting `OperatingSystems/`, `Context.*OS.cs`, `EssentialTools.*`, `ToolRunners/*`, `Configurables.*`, `Application/*`, and `Main.cs` file that only existed to feed the scenarios.
3. Deletes the whole `build-tools/xaprepare/` project.
4. Patches every integration point (`Makefile`, `PrepareWindows.targets`, `BuildEverything.mk`, CI YAML, docs) so `build.cmd -t:Prepare` and `make prepare` still work end-to-end.
## `Configuration.OperatingSystem.props.in` placeholder audit
| Placeholder | Consumers outside the `.in` file | Action |
| --- | --- | --- |
| `HostOsName` | none | drop |
| `HostOsFlavor` | none | drop |
| `HostOsRelease` | none | drop |
| `HostBits` | none (`ArchiveBase.HostBits` in `src/Xamarin.Installer.AndroidSDK/` is an unrelated C# property) | drop |
| `NdkLlvmTag` | none (the NDK toolchain OS tag is resolved elsewhere via `_NdkToolchainOSTag` in `androidsdk.targets`) | drop |
| `HostCpuCount` | only `Configuration.props:72` via `$(MakeConcurrency)` | drop |
## `$(MakeConcurrency)` audit
The only definition was `Configuration.props:72`. A repo-wide grep of `.targets`, `.props`, `.projitems`, `Makefile`, and `.mk` files found zero consumers of the MSBuild property. The `MakeConcurrency` hits under `build-tools/xaprepare/` were an unrelated C# `Context.MakeConcurrency` property.
**Result:** dropped the `MakeConcurrency` MSBuild property entirely (no `$([System.Environment]::ProcessorCount)` replacement needed) and removed the `$(MakeConcurrency)` bullet in `Documentation/building/configuration.md`.
## xaprepare integration audit (grep-confirmed, patched here)
| Location | Change |
| --- | --- |
| `build-tools/xaprepare/` (entire tree) | **deleted** — 86 tracked files |
| `Configuration.props` | dropped `<Import>` of the generated OS props, dropped `MakeConcurrency`, tidied the "between xaprepare and package creation tools" comment |
| `.gitignore` | dropped `Configuration.OperatingSystem.props` |
| `build-tools/scripts/PrepareWindows.targets` | removed `_XAPrepareExe`, `_XAPrepareStandardArgs`, `_BuildXAPrepare` target, and the `Exec dotnet $(_XAPrepareExe)` line. Repointed `Prepare` at `_InstallDotNet`. Kept the space-in-path guard, BootstrapTasks / workloads MSBuilds, and `PrepareJavaInterop` |
| `Makefile` | dropped `PREPARE_PROJECT`, `PREPARE_NET_FX`, `PREPARE_ARGS`, `PREPARE_MSBUILD_FLAGS`, `PREPARE_SCENARIO`, `PREPARE_CI_PR`, `PREPARE_CI`, `_PREPARE_CI_MODE_*`, `_PREPARE_ARGS`, and all their conditionals. Dropped the `dotnet run --project xaprepare.csproj` line from `prepare`. Deleted the `prepare-help` target |
| `build-tools/scripts/BuildEverything.mk` | `jenkins` no longer branches on `PREPARE_CI_PR`/`PREPARE_CI`; just `$(MAKE) prepare && $(MAKE) leeroy` |
| `.github/workflows/copilot-setup-steps.yml` | dropped now-unused `PREPARE_CI=1` |
| `build-tools/automation/azure-pipelines-apidocs.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-linux-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-macos-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/commercial-build.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/copy-extra-result-files.yaml` | dropped `**/Configuration.OperatingSystem.props` glob and the stale `Step_CopyExtraResultFilesForCI` xaprepare-step comment |
| `build-tools/automation/yaml-templates/generate-cgmanifest.yaml` | dropped the stale `Step_GenerateCGManifest` xaprepare-step comment |
| `build-tools/automation/yaml-templates/setup-jdk-variables.yaml` | renamed `$xaPrepareJdkPath` → `$xaJdkPath` for hygiene |
| `Documentation/workflow/HowToAddNewApiLevel.md` | rewrote the "Add New Platform" section to point at `<_PlatformPackage>` entries in `src/androidsdk/androidsdk.targets` instead of `AndroidToolchain.cs`; updated the `--android-sdk-platforms=all` recipe to `dotnet-local build src/androidsdk/androidsdk.csproj -p:AndroidSdkPlatforms=all` |
| `Documentation/building/unix/dependencies.md` | JDK-version link now points at `$(MicrosoftOpenJDKVersion)` in `/Configuration.props` instead of the deleted `Configurables.cs` |
| `Documentation/building/configuration.md` | removed the `$(MakeConcurrency)` bullet |
**Historical breadcrumb comments left as-is** (still accurate and useful for git-archaeology):
- `.github/skills/update-tpn/SKILL.md`
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
- `src/androidsdk/androidsdk.targets`
- `src/native/cmake-config/cmake-config.csproj`
- `src/workloads/workloads.csproj`
## Verification
- `build.cmd Prepare` — succeeded end-to-end on Windows (0 warnings, 0 errors). The trimmed `Prepare` target ran through `_InstallDotNet`, the space-in-path guard, `Xamarin.Android.BootstrapTasks.sln`, `src/workloads/workloads.csproj`, and `PrepareJavaInterop`.
- `dotnet build src\Xamarin.Android.Build.Tasks\Xamarin.Android.Build.Tasks.csproj -c Debug` — 0 errors (93 pre-existing warnings from `src/Mono.Android/` and generated MCW, unrelated to this change).
- Repo-wide grep for `HostOsName`, `HostOsFlavor`, `HostOsRelease`, `HostCpuCount`, `NdkLlvmTag`, and the MSBuild `MakeConcurrency` property — clean.
- Repo-wide grep for `xaprepare` — clean apart from the five intentional historical breadcrumb comments listed above.

Why
bin/configuration.mk exists only to persist CONFIGURATION=<value> between Unix make invocations. Removing it lets us delete the only meaningful contents of Step_GenerateFiles.Unix.cs, continuing the slow removal of xaprepare (see precedent: #11568, #11529).
What
  • Drop -include bin/configuration.mk from the top of Makefile. The CONFIGURATION ?= Debug fallback at the top of the file is unchanged.
  • Delete build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs entirely (it contained GeneratedConfigurationFile and a one-line AddUnixPostBuildSteps partial that registered it).
The partial void AddUnixPostBuildSteps (Context context, List<GeneratedFile> steps); declaration in Step_GenerateFiles.cs is intentionally left in place — partial methods without an implementation are legal in C#, and the call site becomes a zero-cost no-op. Step_GenerateFiles.Windows.cs implements a different partial (AddOSSpecificSteps) and is unaffected.
Why this is safe
CallerPre-change behaviorPost-change behavior
All CI YAML (build-linux-steps.yaml, build-macos-steps.yaml, commercial-build.yaml, azure-pipelines-apidocs.yaml)Passes CONFIGURATION=$(XA.Build.Configuration) on every make callSame — explicit value still wins
build.sh (make prepare && make jenkins && make pack-dotnet)First make prepare runs against an empty bin/, so the -include no-ops and ?= Debug takes effectIdentical — ?= Debug still takes effect
Fresh local checkout, bare make all?= Debug (no bin/configuration.mk yet)Same
Local dev who runs make prepare CONFIGURATION=Release then bare make allPersisted Release via bin/configuration.mkNow defaults back to Debug — must pass CONFIGURATION=Release on every invocation
That last case is the only behavior change. It was never documented as a contract anywhere in Documentation/ or README.md, and developers building Release locally should be passing the flag explicitly anyway.
Verification
  • git grep "configuration\.mk" and git grep "GeneratedConfigurationFile": zero matches after this change.
  • dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj: 0 warnings, 0 errors.
  • Rubber-duck review: no remaining Path.Combine(..., "configuration.mk") references, no Makefile target depends on bin/configuration.mk as a prerequisite, and the leftover partial-method declaration is benign.

[build] Remove unused bin/configuration.mk
1ad2d35
`bin/configuration.mk` existed only to persist `CONFIGURATION=<value>`
between Unix `make` invocations. CI passes `CONFIGURATION=...` explicitly
on every `make` call, and `build.sh` never sets it (so a fresh checkout
always hit the `CONFIGURATION ?= Debug` default anyway). Dropping the
include lets us delete the only meaningful contents of
`Step_GenerateFiles.Unix.cs`, continuing the slow removal of xaprepare.
- Drop `-include bin/configuration.mk` from the top of `Makefile`. The
`CONFIGURATION ?= Debug` fallback is unchanged.
- Delete `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs`
entirely. The `partial void AddUnixPostBuildSteps (...)` declaration in
`Step_GenerateFiles.cs` is left as a no-op (legal C#); the call site
becomes a zero-cost no-op. `Step_GenerateFiles.Windows.cs` implements a
different partial (`AddOSSpecificSteps`) and is unaffected.

Pull request overview
Removes the Unix make configuration persistence mechanism (bin/configuration.mk) as part of the ongoing cleanup/removal of xaprepare, relying solely on the existing CONFIGURATION ?= Debug default and explicit CONFIGURATION=... passed to make.
Changes:
  • Removed -include bin/configuration.mk from the repo Makefile.
  • Deleted the Unix-only xaprepare generated-file step that produced bin/configuration.mk.
Reviewed changes
Copilot reviewed 2 out of 2 changed files in this pull request and generated 1 comment.
FileDescription
MakefileStops including bin/configuration.mk, leaving CONFIGURATION ?= Debug as the sole default mechanism.
build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.csRemoves the generator that created bin/configuration.mk and the Unix partial-step registration.

Drop now-dead AddUnixPostBuildSteps partial
5a770f4
After deleting `Step_GenerateFiles.Unix.cs`, the `partial void
AddUnixPostBuildSteps (...)` declaration and its call site in
`Step_GenerateFiles.cs` were no-ops. Remove them so the file no longer
references a vestige of the `bin/configuration.mk` generator.

[xaprepare] Check inMono.Android.Apis.projitems, remove generator (#…
63951b8
…11608)
`Mono.Android.Apis.projitems` was previously generated at prepare time by
`GeneratedMonoAndroidProjitemsFile` (in xaprepare) from the
`BuildAndroidPlatforms.AllPlatforms` list. Both had exactly one consumer
(each other), so check in the projitems as a source file and drop the
generator plumbing.
Changes:
* Add `src/Mono.Android/Mono.Android.Apis.projitems` — content matches
the generator's output byte-for-byte; only the header comment now
points at `Documentation/workflow/HowToAddNewApiLevel.md` instead of
declaring "GENERATED FILE".
* Repoint the 4 importers (`Mono.Android.targets` x2,
`create-installers.targets`, `create-android-api.csproj`,
`Xamarin.Android.Build.Tasks.targets`) at the new path and drop the
`Condition="Exists(...)"` guards — the file is always present now.
* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* [Xamarin.AndroidTools] Remove dead VS Mac / legacy code (#11607)
Context: after the `android-platform-support` repo was inlined here
(see c22cdcf), `src/Xamarin.AndroidTools/` carries a large amount of
code that was only used by old VS Mac / installer / debugger-host
workflows that are no longer part of the .NET for Android product. None
of these types have callers anywhere in this repo, in
`external/xamarin-android-tools/`, or in `external/Java.Interop/`.
Removed (13 files):
* `PublicationUtilities/PublishAndroidApplication.cs`
* `PublicationUtilities/PackageSigningTasks.cs`
* `PublicationUtilities/KeyManagement.cs`
* `PublicationUtilities/KeystoreEntry.cs`
* `Sessions/AndroidDeploySession.cs`
* `Sessions/AndroidConnectCommandSession.cs`
* `Sessions/AndroidCommandSession.cs`
* `Sessions/AndroidDeploymentException.cs`
* `Devices/AndroidPackageList.cs`
* `Devices/AndroidPackageListExtensions.cs`
* `Debugging/MonoDroidProcessMonitor.cs`
* `PlatformPackage.cs`
* `IProgressNotifier.cs`
* `AndroidSigningOptions.cs`
Moved (still needed by `ProcessUtils.cs`):
* `PublicationUtilities/AndroidSdkToolException.cs` ->
`AndroidSdkToolException.cs` (namespace unchanged)
Pruned from `Devices/AndroidDeviceExtensions.cs` (the methods only
referenced the just-deleted types and had no in-tree callers):
* `StartActivityWithCommandSession` (used `AndroidCommandSession`)
* `GetDeploySession`, `GetPackagesAsync`, `GetPackages` (used
`AndroidDeploySession` / `IProgressNotifier`)
* `InstallSharedRuntime*` and `InstallSharedPlatform*` overloads
that took `IProgressNotifier`
* `GetPackageRemotePath`/`GetPackageRemotePathAsync` (used
`AndroidDeploymentException`)
* `GetFastDevRemotePath`/`GetFastDevRemotePathAsync` and the inner
`FastDevRemotePathInfo` class (only consumer was
`GetPackageRemotePathAsync`)
Kept methods in `AndroidDeviceExtensions.cs` are the ones still used
by `Xamarin.Android.Build.Debugging.Tasks` (`EnsureProperties`,
`KillProcessAndWaitForExit`, `PushAndInstallPackageAsync`) and by
`DebuggingExtensions` (`SetFastDevPropertyFile`, `GetProcessIDAsync`,
`SetDebugPropertiesAsync`).
Also cleaned up:
* `Properties/Resources.resx` (English source): removed seven
`CreateKeyError_*` strings that only `KeyManagement.cs` used.
* `Properties/Resources.Designer.cs`: removed the seven matching
properties.
* `MonoDroidSdk.cs`: two `[Obsolete]` messages referenced the
now-deleted `PlatformPackage`; changed to `"Do not use."`.
Non-English `Resources.*.resx` and `Localize/loc/**/*.lcl` are left
alone per repo policy (auto-regenerated by OneLocBuild).
Build verified locally:
* `src/Xamarin.AndroidTools/Xamarin.AndroidTools.csproj`
* `src/Mono.AndroidTools/Mono.AndroidTools.csproj`
* `src/Xamarin.Android.Build.Debugging.Tasks/Xamarin.Android.Build.Debugging.Tasks.csproj`
* `src/Xamarin.Installer.AndroidSDK/Xamarin.Installer.AndroidSDK.csproj`
Net change: -4225 / +2 lines across 19 files.

NUnit 3.x renamed [TestFixtureSetUp]/[TestFixtureTearDown] to [OneTimeSetUp]/[OneTimeTearDown]. dotnet/java-interop#1437 migrated the Java.Interop test suite to the new names.
The bundled Xamarin.Android.NUnitLite (src-ThirdParty/NUnitLite/) only defines the legacy names. Add no-op subclasses for the new names so test source using [OneTimeSetUp]/[OneTimeTearDown] still compiles against bundled NUnitLite once the Java.Interop submodule is bumped past dotnet/java-interop#1437.
These shims become unnecessary once dotnet/android moves off bundled NUnitLite to stock NUnit (tracked in PR #11224).

[build] Remove Step_PrepareProps; fold values into eng/Versions.props (…
ee0392c
…#11613)
Continues the slow `xaprepare` removal. Recent precedent: #11568 (CopyExtraResultFilesForCI → YAML), #11580 (configuration.mk removal), #11529 (android-platform-support consolidation, which also dropped `Step_PrepareExternalGitDependencies`).
## What
`Step_PrepareProps` generated `external/Java.Interop/Configuration.Override.props` (inside the submodule) by substituting two placeholders into `build-tools/scripts/Configuration.Java.Interop.Override.in.props`. The substituted properties (`_XamarinAndroidCecilVersion`, `UtilityOutputFullPathCoreApps`, `XamarinAndroidToolsDirectory`) are now supplied directly via the checked-in static file `external/Java.Interop.override.props`, which Java.Interop's own `Directory.Build.props` already auto-imports via the parent-dir convention added in dotnet/java-interop#872.
The shared version values (`MonoCecilVersion`, `AndroidPackVersion`, `AndroidPackVersionSuffix`) move into `eng/Versions.props`. `Directory.Build.props` and `external/Java.Interop.override.props` both `<Import>` it. No duplicate-import sentinel is needed because every code path that imports `Configuration.props` has already loaded `Directory.Build.props` (either via MSBuild auto-load or via the explicit `<Import>` in `external/xamarin-android-tools.override.props`).
`MicrosoftAndroidSdkPackName` stays in `Configuration.props` (it is OS-conditioned, not version-shaped, so it doesn't belong in `Versions.props`). The same 3-line OS-conditioned block is mirrored privately in `external/Java.Interop.override.props` as `_MicrosoftAndroidSdkPackName`, used only to compute `UtilityOutputFullPathCoreApps` for the Java.Interop build.
Also dropped:
- `Configurables.Paths.InstallMSBuildDir` and its backing field — the only consumer was `Step_PrepareProps`.
- The dead `UtilityOutputFullPath` line in the old template — Java.Interop's `TargetFrameworkDependentValues.props` unconditionally routes it to `$(UtilityOutputFullPathCoreApps)` anyway, so it was a no-op.
Updated `build-tools/scripts/XAVersionInfo.targets` (the `GitBlame` for `<AndroidPackVersion>` now points at `eng/Versions.props`) and `Documentation/guides/HowToBranch.md` to reflect the moves.
## Why not just `<Import>` `Directory.Build.props` from the Java.Interop override?
That was the original idea. I prototyped it: importing dotnet/android's full props chain from `external/Java.Interop.override.props` flips `DotNetTargetFrameworkVersion` from `10.0` to `11.0` inside Java.Interop, and `dotnet restore Java.Interop.csproj` then fails with:
```
NETSDK1045: The current .NET SDK does not support targeting .NET 11.0
```
`xamarin-android-tools.override.props` gets away with the same trick only because its sole csproj sets `AndroidToolsDisableMultiTargeting=true`, which makes the TFM-clobber harmless. Java.Interop has no equivalent escape hatch.
`eng/Versions.props` is collision-free with Java.Interop (verified against the submodule sources — none of the existing entries collide), has no `<Import>` of its own, and is the safe minimal shared file.
## Verification
On Windows:
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj` — 0 warnings, 0 errors.
- From `src/Xamarin.Android.Build.Tasks/`: `dotnet msbuild --getProperty:MonoCecilVersion,AndroidPackVersion,AndroidPackVersionSuffix,MicrosoftAndroidSdkPackName,MicrosoftAndroidSdkOutDir` — values unchanged from baseline.
- From `external/Java.Interop/src/Java.Interop/`:
- `dotnet msbuild --getProperty:DotNetTargetFramework,_XamarinAndroidCecilVersion,UtilityOutputFullPathCoreApps` returns `net10.0`, `0.11.5`, the expected packs/tools path.
- `dotnet restore Java.Interop.csproj` succeeds (no `NETSDK1045`).

[build] Remove omnisharp.json generation from xaprepare (#11631)
58ccc1f
### Context
`Get_Omnisharp_Json` in `Step_GenerateFiles` substituted two placeholders into `build-tools/scripts/omnisharp.json.in` and wrote `omnisharp.json` at the repo root for OmniSharp / VS Code C# extension users. The generated file was always `.gitignore`d and **nothing in the repo, build, or CI consumes it** — it was purely a local-dev convenience.
Anyone who actually wants an `omnisharp.json` can keep their own local copy (it remains gitignored). Removing this generation slice is another small step in the slow xaprepare reduction, continuing the pattern from #11568, #11580, #11608, and #11613.
### Audit
Before this change `git grep -in "omnisharp"` returned five hits. After it returns only one — the unrelated MSBuild-context guard in `xaprepare.csproj` that prevents xaprepare's targets from importing under OmniSharp's MSBuild process:
```
build-tools/xaprepare/xaprepare/xaprepare.csproj:52:
<Import Project="xaprepare.targets" Condition=" $(MSBuildToolsPath.IndexOf('omnisharp')) < 0 " />
```
That guard is intentional and is **not** touched by this PR.
### Changes
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`: drop the `Get_Omnisharp_Json (context)` entry from the generated-files list and delete the `Get_Omnisharp_Json` method.
- Delete `build-tools/scripts/omnisharp.json.in`.
The shared properties used by the deleted method (`MicrosoftDotnetSdkInternalPackageVersion`, `DotNetPreviewPath`) are still referenced by `Step_InstallDotNetPreview` and `xaprepare.targets`, so they remain.
### Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` — 0 warnings, 0 errors.
- `git grep -in "omnisharp"` — returns only the unrelated `xaprepare.csproj` guard described above.
- No `Documentation/` references to omnisharp; no `.vscode/` folder in the repo.
- Diff: 3 files, 35 deletions, 0 additions.

[xaprepare] Check in Ndk.projitems, remove generator (#11733)
dc54c1c
Mirrors #11608 (which checked in `Mono.Android.Apis.projitems` the same way). See also #11568, #11580, #11613, #11631, #11657, #11658.
## What
`build-tools/scripts/Ndk.projitems.in` was a template with `@NDK_*@` placeholders that the `Get_Ndk_projitems` generator in xaprepare filled in from constants in `BuildAndroidPlatforms.cs`. Those substitution values only change on rare NDK bumps, so generating the file on every build adds no value.
This PR checks in the resolved file as a static `build-tools/scripts/Ndk.projitems` and removes the generator.
## Changes
- **Add** `build-tools/scripts/Ndk.projitems` — the static, checked-in file. Rather than hardcoding values, it sources them from the existing properties in `Configuration.props` (which is imported before `Ndk.targets`):
- `AndroidNdkVersion` → `$(_XAAndroidNdkRelease)`
- `AndroidNdkPkgRevision` → `$(_XAAndroidNdkPkgRevision)`
- the per-ABI `AndroidNdkApiLevel_*` → `$(AndroidMinimumDotNetApiLevel)`
So there is nothing to keep in sync on an NDK/API bump.
- **`build-tools/scripts/Ndk.targets`** — point `ProjitemsFile` at the new in-tree location (`$(MSBuildThisFileDirectory)Ndk.projitems`) instead of `bin/Build$(Configuration)/Ndk.projitems`.
- **Delete** `build-tools/scripts/Ndk.projitems.in`.
- **`Step_GenerateFiles.cs`** — remove the `Get_Ndk_projitems` method and its dispatch entry.
- **`Configurables.cs`** — update a doc comment reference from `Ndk.projitems.in` → `Ndk.projitems`.
### Simplifications (from review)
- **Collapsed the dead legacy/NET API-level split.** The legacy 32-bit minimum API level used to be lower than the .NET minimum, but they are identical now. Removed the two per-ABI properties that nothing references (`AndroidNdkApiLevel_Arm`, `AndroidNdkApiLevel_X86_Legacy`). The `arm64-v8a`/`x86_64` properties are kept because shipped targets (`Build.Tasks.targets`, `Common.props.in`, `NativeAOT.targets`) still consume them by name.
- **Removed the `ApiLevelNET` item metadata.** `ApiLevelNET` was the .NET (.NET 6+) Android minimum API level vs. the legacy Xamarin.Android/Mono `ApiLevel`; the two are identical now and this repo is .NET-only. Its only consumer was `src/native/common/libunwind/libunwind-xamarin.targets`, which now reads `ApiLevel`. Dropped `ApiLevelNET` from all four `AndroidSupportedTargetJitAbi` items.
The NDK constants in `BuildAndroidPlatforms.cs` are intentionally left untouched — they're still consumed by `Get_XABuildConfig_cs` and the cmake presets generator.
## Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 errors / 0 warnings.
- Evaluated the import chain via a standalone MSBuild harness (importing the real `Configuration.props`); it produces all four `AndroidSupportedTargetJitAbi` items with `ApiLevel`=24 and the expected `AndroidRID` metadata, matching prior generator output (NDK `28c` / pkg `28.2.13676358`).
- Audits clean: `git grep Ndk.projitems.in`, `git grep Ndk_projitems`, `git grep ApiLevelNET`, and the old `bin/Build$(Configuration)/Ndk.projitems` path all return 0 hits.

[xaprepare] Remove unused tool runners and helper classes (#11740)
185bf46
Many xaprepare provisioning steps have been removed over the past year (#11332, #11348, #11399, #11440, #11441, #11636 and follow-up cleanups in #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737). The supporting scaffolding around those steps was left behind. This PR removes the verified-dead pieces in two passes.
## Files removed (first pass — original audit)
| File | Justification |
| --- | --- |
| `Application/TestAssembly.cs` | Orphan test infra; only referenced by `TestAssemblyType.cs`. |
| `Application/TestAssemblyType.cs` | Only referenced by `TestAssembly.cs`. |
| `Application/StepWithDownloadProgress.cs` | No subclasses remain. |
| `Application/NDKTool.cs` | NDK provisioning moved to MSBuild in #11440. Last consumer was the also-dead `Configurables.NDKTools` collection (removed below). |
| `ToolRunners/SnRunner.cs` | Strong-naming tool runner; never instantiated. |
| `ToolRunners/SnRunner.OutputSink.cs` | Partial sibling of `SnRunner`. |
| `ToolRunners/CMakeRunner.cs` | Never instantiated. |
| `ToolRunners/CMakeRunner.OutputSink.cs` | Partial sibling of `CMakeRunner`. |
## Files removed (second pass — repo-wide re-audit)
| File | Justification |
| --- | --- |
| `ToolRunners/MakeRunner.Linux.cs` | Partial of `MakeRunner`; type never instantiated. |
| `ToolRunners/MakeRunner.MacOS.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.OutputSink.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MSBuildRunner.cs` | Never instantiated. |
| `ToolRunners/MSBuildRunner.OutputSink.cs` | Partial sibling of `MSBuildRunner`. |
| `ToolRunners/NinjaRunner.cs` | Never instantiated. |
| `ToolRunners/NinjaRunner.OutputSink.cs` | Partial sibling of `NinjaRunner`. |
| `Application/ScenarioNoStandardEndSteps.cs` | Abstract class with zero subclasses. |
## Cascading cleanup
- `ConfigAndData/Configurables.cs` — removed the dead `NDKTools` `List<NDKTool>` collection (lines 132–145). Rest of the file unchanged.
## Removed from initial deletion list after verification
- `Application/Extensions.DictionaryOfProgramVersionParser.cs` — initial name-only audit flagged it as dead, but its `Add` extension method is consumed via dictionary collection-initializer syntax in `Application/VersionFetchers.cs`. The consumer never references the static class by name, which is why the first audit missed it. The file stays.
- `Scenarios/Scenario_Required.cs` — looks unreferenced by static grep, but `Scenario` subclasses are reflectively discovered via the `[Scenario]` attribute in `Context.cs` (`Utilities.GetTypesWithCustomAttribute<ScenarioAttribute> ()`). Live. The file stays.
## Verification
- `git grep -n -w <TypeName>` for each deleted type now returns 0 real hits (only unrelated `"TestAssembly"` string literals in `tests/Microsoft.Android.Sdk.TrimmableTypeMap.Tests/` remain — those are assembly-name strings, not the C# type).
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 warnings, 0 errors.
## Deferred follow-up
The csproj conditionally excludes `*MacOS*` files from compilation when `HostOS != Darwin`, so static dead-code analysis from a Windows/Linux host can't see whether the macOS-only consumers are themselves live. These candidates need verification on a Mac host (or a build matrix) before deletion:
- `Application/PkgProgram.MacOS.cs`
- `Application/HomebrewProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
- `ConfigAndData/Dependencies/MacOS.cs`

[xaprepare] Move CMake file generation into a dedicated MSBuild proje…
5e9346d
…ct (#11760)
Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.
## What changes
Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:
* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.
Both are now generated by a new project:
* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.
### Why a dedicated project (not just a target in `native.targets`)
The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:
* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).
A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.
### Incremental correctness
`_GenerateCMakeFiles` declares fully-anchored `Inputs`:
* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)
so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)
### Cascading deletions in xaprepare
* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.
`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).
### What stays
The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.
## Verification
On Windows:
* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors
Incremental behaviour verified by walking through MSBuild diagnostic output:
* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.
The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.

[xaprepare] Remove vestigial OS dependency provisioning (#11803)
e89fded
### Context
After #11636 (dotnet provisioning step removed) and #11731 (test-deps scenarios removed), `Context.AutoProvision` is `false` by default everywhere except hand-run dev provisioning, which is no longer in use. The per-OS package lists are populated at `OS.Init()` time but `EnsureDependencies` is effectively a no-op:
- `OS.EnsureDependencies()` returns early when `AutoProvision` is false (the default),
- nothing else in the codebase reads from the `Program` derivatives' install/uninstall paths,
- the `BuildToolsInventory` writer remains driven only from `EssentialTools.MacOS.cs` (homebrew version detection).
The `OS.Init() / InitializeDependencies() / EnsureDependencies()` machinery on `OS.cs` itself is intentionally **left in place** here — that's a larger refactor for a follow-up PR. This PR only strips the now-vestigial package-list data and the program/runner classes that fed it.
### Files deleted (Phase F — macOS, 4 files)
- `Application/HomebrewProgram.MacOS.cs`
- `Application/PkgProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
### Files deleted (Phase G — Linux, 5 files)
- `Application/Program.Linux.cs` (`LinuxProgram` base — orphan after subclasses go)
- `Application/Program.ArchLinux.cs`
- `Application/Program.DebianLinux.cs`
- `Application/Program.FedoraLinux.cs`
- `Application/Program.GentooLinux.cs`
### Files deleted (Phase 3 — orphan)
- `Application/IBuildInventoryItem.cs` (only implementor was `HomebrewProgram`; `BuildToolsInventory` itself stays, populated directly by `EssentialTools.MacOS.cs`).
### Files reduced to empty stubs
`ConfigAndData/Dependencies/`:
- `MacOS.cs` — `InitializeDependencies()` no-op (was Homebrew formula list + git fallback).
- `Linux.Arch.cs` — class kept (referenced by `distroMap`); package list removed.
- `Linux.Fedora.cs` — same.
- `Linux.Gentoo.cs` — same.
- `Linux.DebianCommon.cs` — common Debian/Ubuntu package list removed; `Flavor = "Debian"` kept.
- `Linux.UbuntuCommon.cs` — `libtoolPackages` + `NeedLibtool` virtual + `InitOS` override removed (all dead).
- `Linux.Debian.cs` — all per-version package lists (`packages`, `packagesPre10`, `packagesPreTrixie`, `packagesTrixieAndLater`, `packages10AndNewerBuildBots`) removed; release/codename detection (`EnsureVersionInformation`, `DebianUnstableVersionMap`, `IsDebian10OrNewer`, etc.) preserved as conservative scope.
- `Linux.Ubuntu.cs` — `preCosmicPackages`, `cosmicPackages`, `preDiscoPackages` lists + `NeedLibtool` override removed; `UbuntuRelease` + `EnsureVersionInformation` preserved.
- `Linux.Mint.cs` — `NeedLibtool` override removed (the property is gone from the base).
`ConfigAndData/Dependencies/Windows.cs` was already a no-op stub — no edit.
### Verification
Orphan audit (each `git grep -nw <Type> -- 'build-tools/xaprepare/*'` reports **0 hits**):
- `HomebrewProgram`, `PkgProgram`, `BrewRunner`, `PkgutilRunner`
- `ArchLinuxProgram`, `DebianLinuxProgram`, `FedoraLinuxProgram`, `GentooLinuxProgram`, `LinuxProgram`
- `IBuildInventoryItem`
Build:
```
dotnet build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug
Build succeeded. 0 Warning(s) 0 Error(s)
```
### Out of scope (follow-up)
- Removing the abstract `OS.InitializeDependencies()` declaration and the surrounding `EnsureDependencies()` machinery from `OperatingSystems/OS.cs`.
- `VersionFetchers` / `ProgramVersionParser` / `RegexProgramVersionParser` / `SevenZipVersionParser` / `Extensions.DictionaryOfProgramVersionParser.cs` are kept — `Utilities.GetProgramVersion` still queries them from `Program.cs`, `ToolRunner.cs`, `EssentialTools.MacOS.cs`, and `OperatingSystems/MacOS.cs` (brew detection).
### Precedent
#11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740, #11760

[xaprepare] Move XABuildConfig generation to AndroidBuildConfig.dll (#…
788d363
…11826)
## Summary
Moves `XABuildConfig.cs` generation out of `xaprepare` and into a new strong-named class library at `src/AndroidBuildConfig/AndroidBuildConfig.csproj` that produces `AndroidBuildConfig.dll`.
This continues the incremental removal of `xaprepare`, following the precedent set by `cmake-config.csproj` (#11760) and the recent batch #11568, #11580, #11608, #11613, #11631, #11731, #11732, #11733, #11737, #11740, #11803, #11821, #11825.
It also fixes a long-standing wart: previously `XABuildConfig.cs` was `<Compile Include>`'d into three different assemblies (`Xamarin.Android.Build.Tasks`, `Xamarin.ProjectTools`, and `Xamarin.Android.Build.Tests`), so every test that mentioned `XABuildConfig` produced a `CS0436` "type conflicts with imported type" warning — about **22** of them.
Wrapping the type in its own assembly collapses it to a single definition that every consumer references normally. After this change `Xamarin.Android.Build.Tests` builds with **7** warnings (none for `XABuildConfig`).
## How it works
`src/AndroidBuildConfig/AndroidBuildConfig.csproj`:
- `Microsoft.NET.Sdk` / `netstandard2.0`, strong-named with `product.snk`.
- `ProjectReference`s `Xamarin.Android.Tools.AndroidSdk` (for the `AndroidTargetArch` enum used by the template).
- `<UsingTask>`s `ReplaceFileContents`, `GitCommitHash`, and `GitBranch` from `$(PrepTasksAssembly)`, all with `TaskFactory="TaskHostFactory" Runtime="NET"` per repo convention.
- The `_GenerateXABuildConfig` target runs `BeforeTargets="BeforeCompile;CoreCompile"`, computes every substitution from MSBuild properties already exposed by `Configuration.props` (NDK major/minor/micro via `$(_XAAndroidNdkPkgRevision.Split('.'))`, API levels via `Split`/`Contains`, full commit hash via `GitCommitHash.CommitHash`, branch via `GitBranch.Branch`), and writes the file to `$(IntermediateOutputPath)XABuildConfig.cs`. The `<Compile Include>` lives inside the target so it resolves at execution time, when `IntermediateOutputPath` is final.
- `XABuildConfig` is now `public static class` instead of `internal static class`.
The three consumer csprojs lose their `<Compile Include="…XABuildConfig.cs" />` and now have a normal `<ProjectReference Include="…AndroidBuildConfig.csproj" />` (no `ReferenceOutputAssembly="False"`).
`build-tools/installers/create-installers.targets` ships `AndroidBuildConfig.dll` + `.pdb` alongside `Xamarin.Android.Build.Tasks.dll`.
## xaprepare cleanup
Removed dead code that only existed to feed the old `Get_XABuildConfig_cs` step:
- `Step_GenerateFiles.Get_XABuildConfig_cs` and its `GetMajor` / `GetMinor` locals
- `BuildInfo`: `NDKRevision`, `NDKVersionMajor`, `NDKVersionMinor`, `NDKVersionMicro`, `NDKVersion`, `XACommitHash`, `XABranch`, `GatherGitInfo`, `DetermineXACommitInfo`, `cachedNdkVersion`
- `Context`: the `if (SelectedScenario.NeedsGitBuildInfo) { await BuildInfo.GatherGitInfo … }` block
- `Scenario.NeedsGitBuildInfo` (and the `NeedsGitBuildInfo = true;` setters in `Scenario_Standard` and `Scenario_Required`)
- `BuildAndroidPlatforms.cs` — entire file (only contained constants used by the deleted code)
- `Utilities.ParseAndroidPkgRevision`
- `GitRunner.GetTopCommitHash` and `GitRunner.GetBranchName` (class retained — still used by `BuildInfo.DetermineLastVersionChangeCommit`)
## Files
**Added**
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
**Renamed/moved**
- `build-tools/scripts/XABuildConfig.cs.in` → `src/AndroidBuildConfig/XABuildConfig.cs.in` (`static class` → `public static class`)
**Modified**
- `src/Xamarin.Android.Build.Tasks/Xamarin.Android.Build.Tasks.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.ProjectTools/Xamarin.ProjectTools.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Xamarin.Android.Build.Tests.csproj`

- `build-tools/xaprepare/README.md`
**Deleted**
- `build-tools/xaprepare/xaprepare/ConfigAndData/BuildAndroidPlatforms.cs`
## Verification
- `AndroidBuildConfig.csproj`: 0 warnings, 0 errors.
- `Xamarin.Android.Build.Tasks.csproj`: 0 errors, 85 pre-existing unrelated warnings (none for `XABuildConfig`).
- `Xamarin.Android.Build.Tests.csproj`: 0 errors, **7** warnings — down from ~22; all `CS0436 XABuildConfig` conflicts eliminated.
- `xaprepare.csproj`: 0 warnings, 0 errors.
- Generated `XABuildConfig.cs` is semantically identical to the pre-change xaprepare output. The only token difference is the intentional `static class` → `public static class`; everything else (NDK split, API-level major/minor split, supported-ABIs semicolon list, full commit hash, branch name, etc.) matches the previous baseline byte-for-byte.

[xaprepare] Move cgmanifest.json generation from xaprepare to YAML (#…
c7c9458
…11825)
Continues the incremental removal of `xaprepare` by moving the
`cgmanifest.json` generator out of the C# step
`Step_GenerateCGManifest` and into a YAML `pwsh:` step that runs only
on CI.
The file is consumed exclusively by the Azure DevOps Component
Governance Detection task (auto-injected on internal pipelines by
`eng/common/core-templates/job/job.yml`). It is not consumed by any
in-repo build target, so generating it from the C# Prepare step is no
longer necessary.
We cannot drop the file outright: `eng/common` ships CG infrastructure
but it is not yet wired to auto-discover submodules in our pipelines,
so the explicit `cgmanifest.json` is still the source of truth.
Files:
* Added: `build-tools/automation/yaml-templates/generate-cgmanifest.yaml`
* Modified: `build-windows-steps.yaml`, `build-macos-steps.yaml`,
`build-linux-steps.yaml`, `commercial-build.yaml` (call the new
template after the Prepare/`make jenkins` step)
* Modified: `Scenario_Standard.cs` (drop registration)
* Modified: `GitRunner.cs` (remove now-unused `ConfigList` and
`SubmoduleStatus` methods)
* Deleted: `Step_GenerateCGManifest.cs`
Verification: byte-for-byte diff of the YAML-generated
`cgmanifest.json` against the previous C# output on Debug:
Baseline=3144 New=3144
Total byte differences: 0
Precedent PRs in this stream: #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803,
#11821.
### Simplify generate-cgmanifest.yaml using ConvertTo-Json
Replace the hand-rolled StringBuilder JSON emission with PowerShell's
`ConvertTo-Json`. The output is no longer byte-identical to the
previous C# output (2-space indent instead of 4, and slightly
different whitespace), but it is still valid JSON matching the
component-detection-manifest schema. The Azure DevOps Component
Governance Detection task parses the file, so formatting does not
matter.

[xaprepare] Delete redundant Windows JdkInfo.props generator (#11946)
e18dc17
On Windows, xaprepare's Step_GenerateFiles.Windows.cs writes
external/Java.Interop/bin/Build$(Configuration)/JdkInfo.props from
build-tools/xaprepare/xaprepare/Resources/JdkInfo.Windows.props.in.
But this file is immediately overwritten. The PrepareWindows.targets
Prepare flow runs, in order:
1. `dotnet xaprepare -a` — writes JdkInfo.props (this code).
2. `MSBuild Xamarin.Android.BootstrapTasks.sln` — does not read JdkInfo.props.
3. `MSBuild src/workloads/workloads.csproj` — does not read JdkInfo.props.
4. `CallTarget PrepareJavaInterop` → `dotnet build -t:Prepare Java.Interop.sln`
→ external/Java.Interop/build-tools/scripts/Prepare.targets → runs the
`JdkInfo` MSBuild task → overwrites JdkInfo.props with its own generated
content.
Nothing between step 1 and step 4 reads the file, and Java.Interop's Prepare
always regenerates it. Now that external/Java.Interop is in-tree, we can
safely delete the redundant write.
This is the smallest-diff removal:
* Delete Step_GenerateFiles.Windows.cs (the AddOSSpecificSteps partial).
* Delete Resources/JdkInfo.Windows.props.in.
* In Step_GenerateFiles.cs, drop the `partial void AddOSSpecificSteps`
declaration and collapse GetFilesToGenerate so `atBuildStart == false`
returns null. Ctor surface (atBuildStart, onlyRequired) is unchanged so
Scenario_Required.cs is unaffected.
* In Scenario_Standard.cs, remove the AddEndSteps override — the only
thing it did was schedule the now-empty Step_GenerateFiles(atBuildStart:
false).
Preserved (future slices will address these):
* Get_Configuration_OperatingSystem_props (D1).
* OperatingSystems/*.cs and Context.OS.* surface.
* PrepareWindows.targets, DotNet.targets, Java.Interop's Prepare.targets.
Verification:
* dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug
→ Build succeeded. 0 Warning(s). 0 Error(s).
* build.cmd -t:Prepare -c Debug (Windows, cold tree) → succeeds; the file
external/Java.Interop/bin/BuildDebug/JdkInfo.props exists.
* Compare-Object of the resulting JdkInfo.props before vs after this
change → byte-identical (1493 bytes, SHA256
DE59A8061B7657831788FFED7BC1DEECA442E9181605083A4553DE7AC8C003A1),
confirming Java.Interop's overwrite is what always ends up on disk.
* Grep audit under build-tools/xaprepare/: no remaining references to
Step_GenerateFiles.Windows, JdkInfo.Windows.props.in, or
AddOSSpecificSteps.
Follows previous xaprepare deletion slices #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803, #11821,

[xaprepare] Delete Configuration.OperatingSystem.props generator and …
be5272c
…xaprepare project (#11959)
Follow-up to #11956, which moved the JDK half of `Configuration.OperatingSystem.props` to Java.Interop's `JdkInfo.props`. The remaining NDK / OS-info half has zero real consumers, so this PR:
1. Deletes the last generator template (`Configuration.OperatingSystem.props.in`).
2. Cascades through `Step_GenerateFiles`, both `Scenario_*` classes (which now had zero steps), and every supporting `OperatingSystems/`, `Context.*OS.cs`, `EssentialTools.*`, `ToolRunners/*`, `Configurables.*`, `Application/*`, and `Main.cs` file that only existed to feed the scenarios.
3. Deletes the whole `build-tools/xaprepare/` project.
4. Patches every integration point (`Makefile`, `PrepareWindows.targets`, `BuildEverything.mk`, CI YAML, docs) so `build.cmd -t:Prepare` and `make prepare` still work end-to-end.
## `Configuration.OperatingSystem.props.in` placeholder audit
| Placeholder | Consumers outside the `.in` file | Action |
| --- | --- | --- |
| `HostOsName` | none | drop |
| `HostOsFlavor` | none | drop |
| `HostOsRelease` | none | drop |
| `HostBits` | none (`ArchiveBase.HostBits` in `src/Xamarin.Installer.AndroidSDK/` is an unrelated C# property) | drop |
| `NdkLlvmTag` | none (the NDK toolchain OS tag is resolved elsewhere via `_NdkToolchainOSTag` in `androidsdk.targets`) | drop |
| `HostCpuCount` | only `Configuration.props:72` via `$(MakeConcurrency)` | drop |
## `$(MakeConcurrency)` audit
The only definition was `Configuration.props:72`. A repo-wide grep of `.targets`, `.props`, `.projitems`, `Makefile`, and `.mk` files found zero consumers of the MSBuild property. The `MakeConcurrency` hits under `build-tools/xaprepare/` were an unrelated C# `Context.MakeConcurrency` property.
**Result:** dropped the `MakeConcurrency` MSBuild property entirely (no `$([System.Environment]::ProcessorCount)` replacement needed) and removed the `$(MakeConcurrency)` bullet in `Documentation/building/configuration.md`.
## xaprepare integration audit (grep-confirmed, patched here)
| Location | Change |
| --- | --- |
| `build-tools/xaprepare/` (entire tree) | **deleted** — 86 tracked files |
| `Configuration.props` | dropped `<Import>` of the generated OS props, dropped `MakeConcurrency`, tidied the "between xaprepare and package creation tools" comment |
| `.gitignore` | dropped `Configuration.OperatingSystem.props` |
| `build-tools/scripts/PrepareWindows.targets` | removed `_XAPrepareExe`, `_XAPrepareStandardArgs`, `_BuildXAPrepare` target, and the `Exec dotnet $(_XAPrepareExe)` line. Repointed `Prepare` at `_InstallDotNet`. Kept the space-in-path guard, BootstrapTasks / workloads MSBuilds, and `PrepareJavaInterop` |
| `Makefile` | dropped `PREPARE_PROJECT`, `PREPARE_NET_FX`, `PREPARE_ARGS`, `PREPARE_MSBUILD_FLAGS`, `PREPARE_SCENARIO`, `PREPARE_CI_PR`, `PREPARE_CI`, `_PREPARE_CI_MODE_*`, `_PREPARE_ARGS`, and all their conditionals. Dropped the `dotnet run --project xaprepare.csproj` line from `prepare`. Deleted the `prepare-help` target |
| `build-tools/scripts/BuildEverything.mk` | `jenkins` no longer branches on `PREPARE_CI_PR`/`PREPARE_CI`; just `$(MAKE) prepare && $(MAKE) leeroy` |
| `.github/workflows/copilot-setup-steps.yml` | dropped now-unused `PREPARE_CI=1` |
| `build-tools/automation/azure-pipelines-apidocs.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-linux-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-macos-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/commercial-build.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/copy-extra-result-files.yaml` | dropped `**/Configuration.OperatingSystem.props` glob and the stale `Step_CopyExtraResultFilesForCI` xaprepare-step comment |
| `build-tools/automation/yaml-templates/generate-cgmanifest.yaml` | dropped the stale `Step_GenerateCGManifest` xaprepare-step comment |
| `build-tools/automation/yaml-templates/setup-jdk-variables.yaml` | renamed `$xaPrepareJdkPath` → `$xaJdkPath` for hygiene |
| `Documentation/workflow/HowToAddNewApiLevel.md` | rewrote the "Add New Platform" section to point at `<_PlatformPackage>` entries in `src/androidsdk/androidsdk.targets` instead of `AndroidToolchain.cs`; updated the `--android-sdk-platforms=all` recipe to `dotnet-local build src/androidsdk/androidsdk.csproj -p:AndroidSdkPlatforms=all` |
| `Documentation/building/unix/dependencies.md` | JDK-version link now points at `$(MicrosoftOpenJDKVersion)` in `/Configuration.props` instead of the deleted `Configurables.cs` |
| `Documentation/building/configuration.md` | removed the `$(MakeConcurrency)` bullet |
**Historical breadcrumb comments left as-is** (still accurate and useful for git-archaeology):
- `.github/skills/update-tpn/SKILL.md`
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
- `src/androidsdk/androidsdk.targets`
- `src/native/cmake-config/cmake-config.csproj`
- `src/workloads/workloads.csproj`
## Verification
- `build.cmd Prepare` — succeeded end-to-end on Windows (0 warnings, 0 errors). The trimmed `Prepare` target ran through `_InstallDotNet`, the space-in-path guard, `Xamarin.Android.BootstrapTasks.sln`, `src/workloads/workloads.csproj`, and `PrepareJavaInterop`.
- `dotnet build src\Xamarin.Android.Build.Tasks\Xamarin.Android.Build.Tasks.csproj -c Debug` — 0 errors (93 pre-existing warnings from `src/Mono.Android/` and generated MCW, unrelated to this change).
- Repo-wide grep for `HostOsName`, `HostOsFlavor`, `HostOsRelease`, `HostCpuCount`, `NdkLlvmTag`, and the MSBuild `MakeConcurrency` property — clean.
- Repo-wide grep for `xaprepare` — clean apart from the five intentional historical breadcrumb comments listed above.

Why
bin/configuration.mk exists only to persist CONFIGURATION=<value> between Unix make invocations. Removing it lets us delete the only meaningful contents of Step_GenerateFiles.Unix.cs, continuing the slow removal of xaprepare (see precedent: #11568, #11529).
What
  • Drop -include bin/configuration.mk from the top of Makefile. The CONFIGURATION ?= Debug fallback at the top of the file is unchanged.
  • Delete build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs entirely (it contained GeneratedConfigurationFile and a one-line AddUnixPostBuildSteps partial that registered it).
The partial void AddUnixPostBuildSteps (Context context, List<GeneratedFile> steps); declaration in Step_GenerateFiles.cs is intentionally left in place — partial methods without an implementation are legal in C#, and the call site becomes a zero-cost no-op. Step_GenerateFiles.Windows.cs implements a different partial (AddOSSpecificSteps) and is unaffected.
Why this is safe
CallerPre-change behaviorPost-change behavior
All CI YAML (build-linux-steps.yaml, build-macos-steps.yaml, commercial-build.yaml, azure-pipelines-apidocs.yaml)Passes CONFIGURATION=$(XA.Build.Configuration) on every make callSame — explicit value still wins
build.sh (make prepare && make jenkins && make pack-dotnet)First make prepare runs against an empty bin/, so the -include no-ops and ?= Debug takes effectIdentical — ?= Debug still takes effect
Fresh local checkout, bare make all?= Debug (no bin/configuration.mk yet)Same
Local dev who runs make prepare CONFIGURATION=Release then bare make allPersisted Release via bin/configuration.mkNow defaults back to Debug — must pass CONFIGURATION=Release on every invocation
That last case is the only behavior change. It was never documented as a contract anywhere in Documentation/ or README.md, and developers building Release locally should be passing the flag explicitly anyway.
Verification
  • git grep "configuration\.mk" and git grep "GeneratedConfigurationFile": zero matches after this change.
  • dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj: 0 warnings, 0 errors.
  • Rubber-duck review: no remaining Path.Combine(..., "configuration.mk") references, no Makefile target depends on bin/configuration.mk as a prerequisite, and the leftover partial-method declaration is benign.

[build] Remove unused bin/configuration.mk
1ad2d35
`bin/configuration.mk` existed only to persist `CONFIGURATION=<value>`
between Unix `make` invocations. CI passes `CONFIGURATION=...` explicitly
on every `make` call, and `build.sh` never sets it (so a fresh checkout
always hit the `CONFIGURATION ?= Debug` default anyway). Dropping the
include lets us delete the only meaningful contents of
`Step_GenerateFiles.Unix.cs`, continuing the slow removal of xaprepare.
- Drop `-include bin/configuration.mk` from the top of `Makefile`. The
`CONFIGURATION ?= Debug` fallback is unchanged.
- Delete `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs`
entirely. The `partial void AddUnixPostBuildSteps (...)` declaration in
`Step_GenerateFiles.cs` is left as a no-op (legal C#); the call site
becomes a zero-cost no-op. `Step_GenerateFiles.Windows.cs` implements a
different partial (`AddOSSpecificSteps`) and is unaffected.

Pull request overview
Removes the Unix make configuration persistence mechanism (bin/configuration.mk) as part of the ongoing cleanup/removal of xaprepare, relying solely on the existing CONFIGURATION ?= Debug default and explicit CONFIGURATION=... passed to make.
Changes:
  • Removed -include bin/configuration.mk from the repo Makefile.
  • Deleted the Unix-only xaprepare generated-file step that produced bin/configuration.mk.
Reviewed changes
Copilot reviewed 2 out of 2 changed files in this pull request and generated 1 comment.
FileDescription
MakefileStops including bin/configuration.mk, leaving CONFIGURATION ?= Debug as the sole default mechanism.
build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.csRemoves the generator that created bin/configuration.mk and the Unix partial-step registration.

Drop now-dead AddUnixPostBuildSteps partial
5a770f4
After deleting `Step_GenerateFiles.Unix.cs`, the `partial void
AddUnixPostBuildSteps (...)` declaration and its call site in
`Step_GenerateFiles.cs` were no-ops. Remove them so the file no longer
references a vestige of the `bin/configuration.mk` generator.

[xaprepare] Check inMono.Android.Apis.projitems, remove generator (#…
63951b8
…11608)
`Mono.Android.Apis.projitems` was previously generated at prepare time by
`GeneratedMonoAndroidProjitemsFile` (in xaprepare) from the
`BuildAndroidPlatforms.AllPlatforms` list. Both had exactly one consumer
(each other), so check in the projitems as a source file and drop the
generator plumbing.
Changes:
* Add `src/Mono.Android/Mono.Android.Apis.projitems` — content matches
the generator's output byte-for-byte; only the header comment now
points at `Documentation/workflow/HowToAddNewApiLevel.md` instead of
declaring "GENERATED FILE".
* Repoint the 4 importers (`Mono.Android.targets` x2,
`create-installers.targets`, `create-android-api.csproj`,
`Xamarin.Android.Build.Tasks.targets`) at the new path and drop the
`Condition="Exists(...)"` guards — the file is always present now.
* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* [Xamarin.AndroidTools] Remove dead VS Mac / legacy code (#11607)
Context: after the `android-platform-support` repo was inlined here
(see c22cdcf), `src/Xamarin.AndroidTools/` carries a large amount of
code that was only used by old VS Mac / installer / debugger-host
workflows that are no longer part of the .NET for Android product. None
of these types have callers anywhere in this repo, in
`external/xamarin-android-tools/`, or in `external/Java.Interop/`.
Removed (13 files):
* `PublicationUtilities/PublishAndroidApplication.cs`
* `PublicationUtilities/PackageSigningTasks.cs`
* `PublicationUtilities/KeyManagement.cs`
* `PublicationUtilities/KeystoreEntry.cs`
* `Sessions/AndroidDeploySession.cs`
* `Sessions/AndroidConnectCommandSession.cs`
* `Sessions/AndroidCommandSession.cs`
* `Sessions/AndroidDeploymentException.cs`
* `Devices/AndroidPackageList.cs`
* `Devices/AndroidPackageListExtensions.cs`
* `Debugging/MonoDroidProcessMonitor.cs`
* `PlatformPackage.cs`
* `IProgressNotifier.cs`
* `AndroidSigningOptions.cs`
Moved (still needed by `ProcessUtils.cs`):
* `PublicationUtilities/AndroidSdkToolException.cs` ->
`AndroidSdkToolException.cs` (namespace unchanged)
Pruned from `Devices/AndroidDeviceExtensions.cs` (the methods only
referenced the just-deleted types and had no in-tree callers):
* `StartActivityWithCommandSession` (used `AndroidCommandSession`)
* `GetDeploySession`, `GetPackagesAsync`, `GetPackages` (used
`AndroidDeploySession` / `IProgressNotifier`)
* `InstallSharedRuntime*` and `InstallSharedPlatform*` overloads
that took `IProgressNotifier`
* `GetPackageRemotePath`/`GetPackageRemotePathAsync` (used
`AndroidDeploymentException`)
* `GetFastDevRemotePath`/`GetFastDevRemotePathAsync` and the inner
`FastDevRemotePathInfo` class (only consumer was
`GetPackageRemotePathAsync`)
Kept methods in `AndroidDeviceExtensions.cs` are the ones still used
by `Xamarin.Android.Build.Debugging.Tasks` (`EnsureProperties`,
`KillProcessAndWaitForExit`, `PushAndInstallPackageAsync`) and by
`DebuggingExtensions` (`SetFastDevPropertyFile`, `GetProcessIDAsync`,
`SetDebugPropertiesAsync`).
Also cleaned up:
* `Properties/Resources.resx` (English source): removed seven
`CreateKeyError_*` strings that only `KeyManagement.cs` used.
* `Properties/Resources.Designer.cs`: removed the seven matching
properties.
* `MonoDroidSdk.cs`: two `[Obsolete]` messages referenced the
now-deleted `PlatformPackage`; changed to `"Do not use."`.
Non-English `Resources.*.resx` and `Localize/loc/**/*.lcl` are left
alone per repo policy (auto-regenerated by OneLocBuild).
Build verified locally:
* `src/Xamarin.AndroidTools/Xamarin.AndroidTools.csproj`
* `src/Mono.AndroidTools/Mono.AndroidTools.csproj`
* `src/Xamarin.Android.Build.Debugging.Tasks/Xamarin.Android.Build.Debugging.Tasks.csproj`
* `src/Xamarin.Installer.AndroidSDK/Xamarin.Installer.AndroidSDK.csproj`
Net change: -4225 / +2 lines across 19 files.

* [NUnitLite] Add OneTimeSetUp/OneTimeTearDown attribute shims
NUnit 3.x renamed [TestFixtureSetUp]/[TestFixtureTearDown] to [OneTimeSetUp]/[OneTimeTearDown]. dotnet/java-interop#1437 migrated the Java.Interop test suite to the new names.
The bundled Xamarin.Android.NUnitLite (src-ThirdParty/NUnitLite/) only defines the legacy names. Add no-op subclasses for the new names so test source using [OneTimeSetUp]/[OneTimeTearDown] still compiles against bundled NUnitLite once the Java.Interop submodule is bumped past dotnet/java-interop#1437.
These shims become unnecessary once dotnet/android moves off bundled NUnitLite to stock NUnit (tracked in PR #11224).

[build] Remove Step_PrepareProps; fold values into eng/Versions.props (…
ee0392c
…#11613)
Continues the slow `xaprepare` removal. Recent precedent: #11568 (CopyExtraResultFilesForCI → YAML), #11580 (configuration.mk removal), #11529 (android-platform-support consolidation, which also dropped `Step_PrepareExternalGitDependencies`).
## What
`Step_PrepareProps` generated `external/Java.Interop/Configuration.Override.props` (inside the submodule) by substituting two placeholders into `build-tools/scripts/Configuration.Java.Interop.Override.in.props`. The substituted properties (`_XamarinAndroidCecilVersion`, `UtilityOutputFullPathCoreApps`, `XamarinAndroidToolsDirectory`) are now supplied directly via the checked-in static file `external/Java.Interop.override.props`, which Java.Interop's own `Directory.Build.props` already auto-imports via the parent-dir convention added in dotnet/java-interop#872.
The shared version values (`MonoCecilVersion`, `AndroidPackVersion`, `AndroidPackVersionSuffix`) move into `eng/Versions.props`. `Directory.Build.props` and `external/Java.Interop.override.props` both `<Import>` it. No duplicate-import sentinel is needed because every code path that imports `Configuration.props` has already loaded `Directory.Build.props` (either via MSBuild auto-load or via the explicit `<Import>` in `external/xamarin-android-tools.override.props`).
`MicrosoftAndroidSdkPackName` stays in `Configuration.props` (it is OS-conditioned, not version-shaped, so it doesn't belong in `Versions.props`). The same 3-line OS-conditioned block is mirrored privately in `external/Java.Interop.override.props` as `_MicrosoftAndroidSdkPackName`, used only to compute `UtilityOutputFullPathCoreApps` for the Java.Interop build.
Also dropped:
- `Configurables.Paths.InstallMSBuildDir` and its backing field — the only consumer was `Step_PrepareProps`.
- The dead `UtilityOutputFullPath` line in the old template — Java.Interop's `TargetFrameworkDependentValues.props` unconditionally routes it to `$(UtilityOutputFullPathCoreApps)` anyway, so it was a no-op.
Updated `build-tools/scripts/XAVersionInfo.targets` (the `GitBlame` for `<AndroidPackVersion>` now points at `eng/Versions.props`) and `Documentation/guides/HowToBranch.md` to reflect the moves.
## Why not just `<Import>` `Directory.Build.props` from the Java.Interop override?
That was the original idea. I prototyped it: importing dotnet/android's full props chain from `external/Java.Interop.override.props` flips `DotNetTargetFrameworkVersion` from `10.0` to `11.0` inside Java.Interop, and `dotnet restore Java.Interop.csproj` then fails with:
```
NETSDK1045: The current .NET SDK does not support targeting .NET 11.0
```
`xamarin-android-tools.override.props` gets away with the same trick only because its sole csproj sets `AndroidToolsDisableMultiTargeting=true`, which makes the TFM-clobber harmless. Java.Interop has no equivalent escape hatch.
`eng/Versions.props` is collision-free with Java.Interop (verified against the submodule sources — none of the existing entries collide), has no `<Import>` of its own, and is the safe minimal shared file.
## Verification
On Windows:
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj` — 0 warnings, 0 errors.
- From `src/Xamarin.Android.Build.Tasks/`: `dotnet msbuild --getProperty:MonoCecilVersion,AndroidPackVersion,AndroidPackVersionSuffix,MicrosoftAndroidSdkPackName,MicrosoftAndroidSdkOutDir` — values unchanged from baseline.
- From `external/Java.Interop/src/Java.Interop/`:
- `dotnet msbuild --getProperty:DotNetTargetFramework,_XamarinAndroidCecilVersion,UtilityOutputFullPathCoreApps` returns `net10.0`, `0.11.5`, the expected packs/tools path.
- `dotnet restore Java.Interop.csproj` succeeds (no `NETSDK1045`).

[build] Remove omnisharp.json generation from xaprepare (#11631)
58ccc1f
### Context
`Get_Omnisharp_Json` in `Step_GenerateFiles` substituted two placeholders into `build-tools/scripts/omnisharp.json.in` and wrote `omnisharp.json` at the repo root for OmniSharp / VS Code C# extension users. The generated file was always `.gitignore`d and **nothing in the repo, build, or CI consumes it** — it was purely a local-dev convenience.
Anyone who actually wants an `omnisharp.json` can keep their own local copy (it remains gitignored). Removing this generation slice is another small step in the slow xaprepare reduction, continuing the pattern from #11568, #11580, #11608, and #11613.
### Audit
Before this change `git grep -in "omnisharp"` returned five hits. After it returns only one — the unrelated MSBuild-context guard in `xaprepare.csproj` that prevents xaprepare's targets from importing under OmniSharp's MSBuild process:
```
build-tools/xaprepare/xaprepare/xaprepare.csproj:52:
<Import Project="xaprepare.targets" Condition=" $(MSBuildToolsPath.IndexOf('omnisharp')) < 0 " />
```
That guard is intentional and is **not** touched by this PR.
### Changes
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`: drop the `Get_Omnisharp_Json (context)` entry from the generated-files list and delete the `Get_Omnisharp_Json` method.
- Delete `build-tools/scripts/omnisharp.json.in`.
The shared properties used by the deleted method (`MicrosoftDotnetSdkInternalPackageVersion`, `DotNetPreviewPath`) are still referenced by `Step_InstallDotNetPreview` and `xaprepare.targets`, so they remain.
### Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` — 0 warnings, 0 errors.
- `git grep -in "omnisharp"` — returns only the unrelated `xaprepare.csproj` guard described above.
- No `Documentation/` references to omnisharp; no `.vscode/` folder in the repo.
- Diff: 3 files, 35 deletions, 0 additions.

[xaprepare] Check in Ndk.projitems, remove generator (#11733)
dc54c1c
Mirrors #11608 (which checked in `Mono.Android.Apis.projitems` the same way). See also #11568, #11580, #11613, #11631, #11657, #11658.
## What
`build-tools/scripts/Ndk.projitems.in` was a template with `@NDK_*@` placeholders that the `Get_Ndk_projitems` generator in xaprepare filled in from constants in `BuildAndroidPlatforms.cs`. Those substitution values only change on rare NDK bumps, so generating the file on every build adds no value.
This PR checks in the resolved file as a static `build-tools/scripts/Ndk.projitems` and removes the generator.
## Changes
- **Add** `build-tools/scripts/Ndk.projitems` — the static, checked-in file. Rather than hardcoding values, it sources them from the existing properties in `Configuration.props` (which is imported before `Ndk.targets`):
- `AndroidNdkVersion` → `$(_XAAndroidNdkRelease)`
- `AndroidNdkPkgRevision` → `$(_XAAndroidNdkPkgRevision)`
- the per-ABI `AndroidNdkApiLevel_*` → `$(AndroidMinimumDotNetApiLevel)`
So there is nothing to keep in sync on an NDK/API bump.
- **`build-tools/scripts/Ndk.targets`** — point `ProjitemsFile` at the new in-tree location (`$(MSBuildThisFileDirectory)Ndk.projitems`) instead of `bin/Build$(Configuration)/Ndk.projitems`.
- **Delete** `build-tools/scripts/Ndk.projitems.in`.
- **`Step_GenerateFiles.cs`** — remove the `Get_Ndk_projitems` method and its dispatch entry.
- **`Configurables.cs`** — update a doc comment reference from `Ndk.projitems.in` → `Ndk.projitems`.
### Simplifications (from review)
- **Collapsed the dead legacy/NET API-level split.** The legacy 32-bit minimum API level used to be lower than the .NET minimum, but they are identical now. Removed the two per-ABI properties that nothing references (`AndroidNdkApiLevel_Arm`, `AndroidNdkApiLevel_X86_Legacy`). The `arm64-v8a`/`x86_64` properties are kept because shipped targets (`Build.Tasks.targets`, `Common.props.in`, `NativeAOT.targets`) still consume them by name.
- **Removed the `ApiLevelNET` item metadata.** `ApiLevelNET` was the .NET (.NET 6+) Android minimum API level vs. the legacy Xamarin.Android/Mono `ApiLevel`; the two are identical now and this repo is .NET-only. Its only consumer was `src/native/common/libunwind/libunwind-xamarin.targets`, which now reads `ApiLevel`. Dropped `ApiLevelNET` from all four `AndroidSupportedTargetJitAbi` items.
The NDK constants in `BuildAndroidPlatforms.cs` are intentionally left untouched — they're still consumed by `Get_XABuildConfig_cs` and the cmake presets generator.
## Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 errors / 0 warnings.
- Evaluated the import chain via a standalone MSBuild harness (importing the real `Configuration.props`); it produces all four `AndroidSupportedTargetJitAbi` items with `ApiLevel`=24 and the expected `AndroidRID` metadata, matching prior generator output (NDK `28c` / pkg `28.2.13676358`).
- Audits clean: `git grep Ndk.projitems.in`, `git grep Ndk_projitems`, `git grep ApiLevelNET`, and the old `bin/Build$(Configuration)/Ndk.projitems` path all return 0 hits.

[xaprepare] Remove unused tool runners and helper classes (#11740)
185bf46
Many xaprepare provisioning steps have been removed over the past year (#11332, #11348, #11399, #11440, #11441, #11636 and follow-up cleanups in #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737). The supporting scaffolding around those steps was left behind. This PR removes the verified-dead pieces in two passes.
## Files removed (first pass — original audit)
| File | Justification |
| --- | --- |
| `Application/TestAssembly.cs` | Orphan test infra; only referenced by `TestAssemblyType.cs`. |
| `Application/TestAssemblyType.cs` | Only referenced by `TestAssembly.cs`. |
| `Application/StepWithDownloadProgress.cs` | No subclasses remain. |
| `Application/NDKTool.cs` | NDK provisioning moved to MSBuild in #11440. Last consumer was the also-dead `Configurables.NDKTools` collection (removed below). |
| `ToolRunners/SnRunner.cs` | Strong-naming tool runner; never instantiated. |
| `ToolRunners/SnRunner.OutputSink.cs` | Partial sibling of `SnRunner`. |
| `ToolRunners/CMakeRunner.cs` | Never instantiated. |
| `ToolRunners/CMakeRunner.OutputSink.cs` | Partial sibling of `CMakeRunner`. |
## Files removed (second pass — repo-wide re-audit)
| File | Justification |
| --- | --- |
| `ToolRunners/MakeRunner.Linux.cs` | Partial of `MakeRunner`; type never instantiated. |
| `ToolRunners/MakeRunner.MacOS.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.OutputSink.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MSBuildRunner.cs` | Never instantiated. |
| `ToolRunners/MSBuildRunner.OutputSink.cs` | Partial sibling of `MSBuildRunner`. |
| `ToolRunners/NinjaRunner.cs` | Never instantiated. |
| `ToolRunners/NinjaRunner.OutputSink.cs` | Partial sibling of `NinjaRunner`. |
| `Application/ScenarioNoStandardEndSteps.cs` | Abstract class with zero subclasses. |
## Cascading cleanup
- `ConfigAndData/Configurables.cs` — removed the dead `NDKTools` `List<NDKTool>` collection (lines 132–145). Rest of the file unchanged.
## Removed from initial deletion list after verification
- `Application/Extensions.DictionaryOfProgramVersionParser.cs` — initial name-only audit flagged it as dead, but its `Add` extension method is consumed via dictionary collection-initializer syntax in `Application/VersionFetchers.cs`. The consumer never references the static class by name, which is why the first audit missed it. The file stays.
- `Scenarios/Scenario_Required.cs` — looks unreferenced by static grep, but `Scenario` subclasses are reflectively discovered via the `[Scenario]` attribute in `Context.cs` (`Utilities.GetTypesWithCustomAttribute<ScenarioAttribute> ()`). Live. The file stays.
## Verification
- `git grep -n -w <TypeName>` for each deleted type now returns 0 real hits (only unrelated `"TestAssembly"` string literals in `tests/Microsoft.Android.Sdk.TrimmableTypeMap.Tests/` remain — those are assembly-name strings, not the C# type).
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 warnings, 0 errors.
## Deferred follow-up
The csproj conditionally excludes `*MacOS*` files from compilation when `HostOS != Darwin`, so static dead-code analysis from a Windows/Linux host can't see whether the macOS-only consumers are themselves live. These candidates need verification on a Mac host (or a build matrix) before deletion:
- `Application/PkgProgram.MacOS.cs`
- `Application/HomebrewProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
- `ConfigAndData/Dependencies/MacOS.cs`

[xaprepare] Move CMake file generation into a dedicated MSBuild proje…
5e9346d
…ct (#11760)
Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.
## What changes
Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:
* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.
Both are now generated by a new project:
* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.
### Why a dedicated project (not just a target in `native.targets`)
The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:
* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).
A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.
### Incremental correctness
`_GenerateCMakeFiles` declares fully-anchored `Inputs`:
* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)
so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)
### Cascading deletions in xaprepare
* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.
`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).
### What stays
The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.
## Verification
On Windows:
* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors
Incremental behaviour verified by walking through MSBuild diagnostic output:
* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.
The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.

[xaprepare] Remove vestigial OS dependency provisioning (#11803)
e89fded
### Context
After #11636 (dotnet provisioning step removed) and #11731 (test-deps scenarios removed), `Context.AutoProvision` is `false` by default everywhere except hand-run dev provisioning, which is no longer in use. The per-OS package lists are populated at `OS.Init()` time but `EnsureDependencies` is effectively a no-op:
- `OS.EnsureDependencies()` returns early when `AutoProvision` is false (the default),
- nothing else in the codebase reads from the `Program` derivatives' install/uninstall paths,
- the `BuildToolsInventory` writer remains driven only from `EssentialTools.MacOS.cs` (homebrew version detection).
The `OS.Init() / InitializeDependencies() / EnsureDependencies()` machinery on `OS.cs` itself is intentionally **left in place** here — that's a larger refactor for a follow-up PR. This PR only strips the now-vestigial package-list data and the program/runner classes that fed it.
### Files deleted (Phase F — macOS, 4 files)
- `Application/HomebrewProgram.MacOS.cs`
- `Application/PkgProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
### Files deleted (Phase G — Linux, 5 files)
- `Application/Program.Linux.cs` (`LinuxProgram` base — orphan after subclasses go)
- `Application/Program.ArchLinux.cs`
- `Application/Program.DebianLinux.cs`
- `Application/Program.FedoraLinux.cs`
- `Application/Program.GentooLinux.cs`
### Files deleted (Phase 3 — orphan)
- `Application/IBuildInventoryItem.cs` (only implementor was `HomebrewProgram`; `BuildToolsInventory` itself stays, populated directly by `EssentialTools.MacOS.cs`).
### Files reduced to empty stubs
`ConfigAndData/Dependencies/`:
- `MacOS.cs` — `InitializeDependencies()` no-op (was Homebrew formula list + git fallback).
- `Linux.Arch.cs` — class kept (referenced by `distroMap`); package list removed.
- `Linux.Fedora.cs` — same.
- `Linux.Gentoo.cs` — same.
- `Linux.DebianCommon.cs` — common Debian/Ubuntu package list removed; `Flavor = "Debian"` kept.
- `Linux.UbuntuCommon.cs` — `libtoolPackages` + `NeedLibtool` virtual + `InitOS` override removed (all dead).
- `Linux.Debian.cs` — all per-version package lists (`packages`, `packagesPre10`, `packagesPreTrixie`, `packagesTrixieAndLater`, `packages10AndNewerBuildBots`) removed; release/codename detection (`EnsureVersionInformation`, `DebianUnstableVersionMap`, `IsDebian10OrNewer`, etc.) preserved as conservative scope.
- `Linux.Ubuntu.cs` — `preCosmicPackages`, `cosmicPackages`, `preDiscoPackages` lists + `NeedLibtool` override removed; `UbuntuRelease` + `EnsureVersionInformation` preserved.
- `Linux.Mint.cs` — `NeedLibtool` override removed (the property is gone from the base).
`ConfigAndData/Dependencies/Windows.cs` was already a no-op stub — no edit.
### Verification
Orphan audit (each `git grep -nw <Type> -- 'build-tools/xaprepare/*'` reports **0 hits**):

### Out of scope (follow-up)
- Removing the abstract `OS.InitializeDependencies()` declaration and the surrounding `EnsureDependencies()` machinery from `OperatingSystems/OS.cs`.
- `VersionFetchers` / `ProgramVersionParser` / `RegexProgramVersionParser` / `SevenZipVersionParser` / `Extensions.DictionaryOfProgramVersionParser.cs` are kept — `Utilities.GetProgramVersion` still queries them from `Program.cs`, `ToolRunner.cs`, `EssentialTools.MacOS.cs`, and `OperatingSystems/MacOS.cs` (brew detection).

[xaprepare] Move XABuildConfig generation to AndroidBuildConfig.dll (#…
788d363
…11826)
## Summary
Moves `XABuildConfig.cs` generation out of `xaprepare` and into a new strong-named class library at `src/AndroidBuildConfig/AndroidBuildConfig.csproj` that produces `AndroidBuildConfig.dll`.
This continues the incremental removal of `xaprepare`, following the precedent set by `cmake-config.csproj` (#11760) and the recent batch #11568, #11580, #11608, #11613, #11631, #11731, #11732, #11733, #11737, #11740, #11803, #11821, #11825.
It also fixes a long-standing wart: previously `XABuildConfig.cs` was `<Compile Include>`'d into three different assemblies (`Xamarin.Android.Build.Tasks`, `Xamarin.ProjectTools`, and `Xamarin.Android.Build.Tests`), so every test that mentioned `XABuildConfig` produced a `CS0436` "type conflicts with imported type" warning — about **22** of them.
Wrapping the type in its own assembly collapses it to a single definition that every consumer references normally. After this change `Xamarin.Android.Build.Tests` builds with **7** warnings (none for `XABuildConfig`).
## How it works
`src/AndroidBuildConfig/AndroidBuildConfig.csproj`:
- `Microsoft.NET.Sdk` / `netstandard2.0`, strong-named with `product.snk`.
- `ProjectReference`s `Xamarin.Android.Tools.AndroidSdk` (for the `AndroidTargetArch` enum used by the template).
- `<UsingTask>`s `ReplaceFileContents`, `GitCommitHash`, and `GitBranch` from `$(PrepTasksAssembly)`, all with `TaskFactory="TaskHostFactory" Runtime="NET"` per repo convention.
- The `_GenerateXABuildConfig` target runs `BeforeTargets="BeforeCompile;CoreCompile"`, computes every substitution from MSBuild properties already exposed by `Configuration.props` (NDK major/minor/micro via `$(_XAAndroidNdkPkgRevision.Split('.'))`, API levels via `Split`/`Contains`, full commit hash via `GitCommitHash.CommitHash`, branch via `GitBranch.Branch`), and writes the file to `$(IntermediateOutputPath)XABuildConfig.cs`. The `<Compile Include>` lives inside the target so it resolves at execution time, when `IntermediateOutputPath` is final.
- `XABuildConfig` is now `public static class` instead of `internal static class`.
The three consumer csprojs lose their `<Compile Include="…XABuildConfig.cs" />` and now have a normal `<ProjectReference Include="…AndroidBuildConfig.csproj" />` (no `ReferenceOutputAssembly="False"`).
`build-tools/installers/create-installers.targets` ships `AndroidBuildConfig.dll` + `.pdb` alongside `Xamarin.Android.Build.Tasks.dll`.
## xaprepare cleanup
Removed dead code that only existed to feed the old `Get_XABuildConfig_cs` step:
- `Step_GenerateFiles.Get_XABuildConfig_cs` and its `GetMajor` / `GetMinor` locals
- `BuildInfo`: `NDKRevision`, `NDKVersionMajor`, `NDKVersionMinor`, `NDKVersionMicro`, `NDKVersion`, `XACommitHash`, `XABranch`, `GatherGitInfo`, `DetermineXACommitInfo`, `cachedNdkVersion`
- `Context`: the `if (SelectedScenario.NeedsGitBuildInfo) { await BuildInfo.GatherGitInfo … }` block
- `Scenario.NeedsGitBuildInfo` (and the `NeedsGitBuildInfo = true;` setters in `Scenario_Standard` and `Scenario_Required`)
- `BuildAndroidPlatforms.cs` — entire file (only contained constants used by the deleted code)
- `Utilities.ParseAndroidPkgRevision`
- `GitRunner.GetTopCommitHash` and `GitRunner.GetBranchName` (class retained — still used by `BuildInfo.DetermineLastVersionChangeCommit`)
## Files
**Added**
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
**Renamed/moved**
- `build-tools/scripts/XABuildConfig.cs.in` → `src/AndroidBuildConfig/XABuildConfig.cs.in` (`static class` → `public static class`)
**Modified**
- `src/Xamarin.Android.Build.Tasks/Xamarin.Android.Build.Tasks.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.ProjectTools/Xamarin.ProjectTools.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Xamarin.Android.Build.Tests.csproj`
- `build-tools/installers/create-installers.targets`
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`
- `build-tools/xaprepare/xaprepare/Application/BuildInfo.cs`
- `build-tools/xaprepare/xaprepare/Application/Context.cs`
- `build-tools/xaprepare/xaprepare/Application/Scenario.cs`
- `build-tools/xaprepare/xaprepare/Application/Utilities.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Standard.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Required.cs`
- `build-tools/xaprepare/xaprepare/ToolRunners/GitRunner.cs`
- `build-tools/xaprepare/README.md`
**Deleted**
- `build-tools/xaprepare/xaprepare/ConfigAndData/BuildAndroidPlatforms.cs`
## Verification
- `AndroidBuildConfig.csproj`: 0 warnings, 0 errors.
- `Xamarin.Android.Build.Tasks.csproj`: 0 errors, 85 pre-existing unrelated warnings (none for `XABuildConfig`).
- `Xamarin.Android.Build.Tests.csproj`: 0 errors, **7** warnings — down from ~22; all `CS0436 XABuildConfig` conflicts eliminated.
- `xaprepare.csproj`: 0 warnings, 0 errors.
- Generated `XABuildConfig.cs` is semantically identical to the pre-change xaprepare output. The only token difference is the intentional `static class` → `public static class`; everything else (NDK split, API-level major/minor split, supported-ABIs semicolon list, full commit hash, branch name, etc.) matches the previous baseline byte-for-byte.

[xaprepare] Move cgmanifest.json generation from xaprepare to YAML (#…
c7c9458
…11825)
Continues the incremental removal of `xaprepare` by moving the
`cgmanifest.json` generator out of the C# step
`Step_GenerateCGManifest` and into a YAML `pwsh:` step that runs only
on CI.
The file is consumed exclusively by the Azure DevOps Component
Governance Detection task (auto-injected on internal pipelines by
`eng/common/core-templates/job/job.yml`). It is not consumed by any
in-repo build target, so generating it from the C# Prepare step is no
longer necessary.
We cannot drop the file outright: `eng/common` ships CG infrastructure
but it is not yet wired to auto-discover submodules in our pipelines,
so the explicit `cgmanifest.json` is still the source of truth.
Files:
* Added: `build-tools/automation/yaml-templates/generate-cgmanifest.yaml`
* Modified: `build-windows-steps.yaml`, `build-macos-steps.yaml`,
`build-linux-steps.yaml`, `commercial-build.yaml` (call the new
template after the Prepare/`make jenkins` step)
* Modified: `Scenario_Standard.cs` (drop registration)
* Modified: `GitRunner.cs` (remove now-unused `ConfigList` and
`SubmoduleStatus` methods)
* Deleted: `Step_GenerateCGManifest.cs`
Verification: byte-for-byte diff of the YAML-generated
`cgmanifest.json` against the previous C# output on Debug:
Baseline=3144 New=3144
Total byte differences: 0
Precedent PRs in this stream: #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803,
#11821.
### Simplify generate-cgmanifest.yaml using ConvertTo-Json
Replace the hand-rolled StringBuilder JSON emission with PowerShell's
`ConvertTo-Json`. The output is no longer byte-identical to the
previous C# output (2-space indent instead of 4, and slightly
different whitespace), but it is still valid JSON matching the
component-detection-manifest schema. The Azure DevOps Component
Governance Detection task parses the file, so formatting does not
matter.

[xaprepare] Delete redundant Windows JdkInfo.props generator (#11946)
e18dc17
On Windows, xaprepare's Step_GenerateFiles.Windows.cs writes
external/Java.Interop/bin/Build$(Configuration)/JdkInfo.props from
build-tools/xaprepare/xaprepare/Resources/JdkInfo.Windows.props.in.
But this file is immediately overwritten. The PrepareWindows.targets
Prepare flow runs, in order:
1. `dotnet xaprepare -a` — writes JdkInfo.props (this code).
2. `MSBuild Xamarin.Android.BootstrapTasks.sln` — does not read JdkInfo.props.
3. `MSBuild src/workloads/workloads.csproj` — does not read JdkInfo.props.
4. `CallTarget PrepareJavaInterop` → `dotnet build -t:Prepare Java.Interop.sln`
→ external/Java.Interop/build-tools/scripts/Prepare.targets → runs the
`JdkInfo` MSBuild task → overwrites JdkInfo.props with its own generated
content.
Nothing between step 1 and step 4 reads the file, and Java.Interop's Prepare
always regenerates it. Now that external/Java.Interop is in-tree, we can
safely delete the redundant write.
This is the smallest-diff removal:
* Delete Step_GenerateFiles.Windows.cs (the AddOSSpecificSteps partial).
* Delete Resources/JdkInfo.Windows.props.in.
* In Step_GenerateFiles.cs, drop the `partial void AddOSSpecificSteps`
declaration and collapse GetFilesToGenerate so `atBuildStart == false`
returns null. Ctor surface (atBuildStart, onlyRequired) is unchanged so
Scenario_Required.cs is unaffected.
* In Scenario_Standard.cs, remove the AddEndSteps override — the only
thing it did was schedule the now-empty Step_GenerateFiles(atBuildStart:
false).
Preserved (future slices will address these):
* Get_Configuration_OperatingSystem_props (D1).
* OperatingSystems/*.cs and Context.OS.* surface.
* PrepareWindows.targets, DotNet.targets, Java.Interop's Prepare.targets.
Verification:
* dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug
→ Build succeeded. 0 Warning(s). 0 Error(s).
* build.cmd -t:Prepare -c Debug (Windows, cold tree) → succeeds; the file
external/Java.Interop/bin/BuildDebug/JdkInfo.props exists.
* Compare-Object of the resulting JdkInfo.props before vs after this
change → byte-identical (1493 bytes, SHA256
DE59A8061B7657831788FFED7BC1DEECA442E9181605083A4553DE7AC8C003A1),
confirming Java.Interop's overwrite is what always ends up on disk.
* Grep audit under build-tools/xaprepare/: no remaining references to
Step_GenerateFiles.Windows, JdkInfo.Windows.props.in, or
AddOSSpecificSteps.
Follows previous xaprepare deletion slices #11568, #11580, #11608, #11613,

[xaprepare] Delete Configuration.OperatingSystem.props generator and …
be5272c
…xaprepare project (#11959)
Follow-up to #11956, which moved the JDK half of `Configuration.OperatingSystem.props` to Java.Interop's `JdkInfo.props`. The remaining NDK / OS-info half has zero real consumers, so this PR:
1. Deletes the last generator template (`Configuration.OperatingSystem.props.in`).
2. Cascades through `Step_GenerateFiles`, both `Scenario_*` classes (which now had zero steps), and every supporting `OperatingSystems/`, `Context.*OS.cs`, `EssentialTools.*`, `ToolRunners/*`, `Configurables.*`, `Application/*`, and `Main.cs` file that only existed to feed the scenarios.
3. Deletes the whole `build-tools/xaprepare/` project.
4. Patches every integration point (`Makefile`, `PrepareWindows.targets`, `BuildEverything.mk`, CI YAML, docs) so `build.cmd -t:Prepare` and `make prepare` still work end-to-end.
## `Configuration.OperatingSystem.props.in` placeholder audit
| Placeholder | Consumers outside the `.in` file | Action |
| --- | --- | --- |
| `HostOsName` | none | drop |
| `HostOsFlavor` | none | drop |
| `HostOsRelease` | none | drop |
| `HostBits` | none (`ArchiveBase.HostBits` in `src/Xamarin.Installer.AndroidSDK/` is an unrelated C# property) | drop |
| `NdkLlvmTag` | none (the NDK toolchain OS tag is resolved elsewhere via `_NdkToolchainOSTag` in `androidsdk.targets`) | drop |
| `HostCpuCount` | only `Configuration.props:72` via `$(MakeConcurrency)` | drop |
## `$(MakeConcurrency)` audit
The only definition was `Configuration.props:72`. A repo-wide grep of `.targets`, `.props`, `.projitems`, `Makefile`, and `.mk` files found zero consumers of the MSBuild property. The `MakeConcurrency` hits under `build-tools/xaprepare/` were an unrelated C# `Context.MakeConcurrency` property.
**Result:** dropped the `MakeConcurrency` MSBuild property entirely (no `$([System.Environment]::ProcessorCount)` replacement needed) and removed the `$(MakeConcurrency)` bullet in `Documentation/building/configuration.md`.
## xaprepare integration audit (grep-confirmed, patched here)
| Location | Change |
| --- | --- |
| `build-tools/xaprepare/` (entire tree) | **deleted** — 86 tracked files |
| `Configuration.props` | dropped `<Import>` of the generated OS props, dropped `MakeConcurrency`, tidied the "between xaprepare and package creation tools" comment |
| `.gitignore` | dropped `Configuration.OperatingSystem.props` |
| `build-tools/scripts/PrepareWindows.targets` | removed `_XAPrepareExe`, `_XAPrepareStandardArgs`, `_BuildXAPrepare` target, and the `Exec dotnet $(_XAPrepareExe)` line. Repointed `Prepare` at `_InstallDotNet`. Kept the space-in-path guard, BootstrapTasks / workloads MSBuilds, and `PrepareJavaInterop` |
| `Makefile` | dropped `PREPARE_PROJECT`, `PREPARE_NET_FX`, `PREPARE_ARGS`, `PREPARE_MSBUILD_FLAGS`, `PREPARE_SCENARIO`, `PREPARE_CI_PR`, `PREPARE_CI`, `_PREPARE_CI_MODE_*`, `_PREPARE_ARGS`, and all their conditionals. Dropped the `dotnet run --project xaprepare.csproj` line from `prepare`. Deleted the `prepare-help` target |
| `build-tools/scripts/BuildEverything.mk` | `jenkins` no longer branches on `PREPARE_CI_PR`/`PREPARE_CI`; just `$(MAKE) prepare && $(MAKE) leeroy` |
| `.github/workflows/copilot-setup-steps.yml` | dropped now-unused `PREPARE_CI=1` |
| `build-tools/automation/azure-pipelines-apidocs.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-linux-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-macos-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/commercial-build.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/copy-extra-result-files.yaml` | dropped `**/Configuration.OperatingSystem.props` glob and the stale `Step_CopyExtraResultFilesForCI` xaprepare-step comment |
| `build-tools/automation/yaml-templates/generate-cgmanifest.yaml` | dropped the stale `Step_GenerateCGManifest` xaprepare-step comment |
| `build-tools/automation/yaml-templates/setup-jdk-variables.yaml` | renamed `$xaPrepareJdkPath` → `$xaJdkPath` for hygiene |
| `Documentation/workflow/HowToAddNewApiLevel.md` | rewrote the "Add New Platform" section to point at `<_PlatformPackage>` entries in `src/androidsdk/androidsdk.targets` instead of `AndroidToolchain.cs`; updated the `--android-sdk-platforms=all` recipe to `dotnet-local build src/androidsdk/androidsdk.csproj -p:AndroidSdkPlatforms=all` |
| `Documentation/building/unix/dependencies.md` | JDK-version link now points at `$(MicrosoftOpenJDKVersion)` in `/Configuration.props` instead of the deleted `Configurables.cs` |
| `Documentation/building/configuration.md` | removed the `$(MakeConcurrency)` bullet |
**Historical breadcrumb comments left as-is** (still accurate and useful for git-archaeology):
- `.github/skills/update-tpn/SKILL.md`
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
- `src/androidsdk/androidsdk.targets`
- `src/native/cmake-config/cmake-config.csproj`
- `src/workloads/workloads.csproj`
## Verification
- `build.cmd Prepare` — succeeded end-to-end on Windows (0 warnings, 0 errors). The trimmed `Prepare` target ran through `_InstallDotNet`, the space-in-path guard, `Xamarin.Android.BootstrapTasks.sln`, `src/workloads/workloads.csproj`, and `PrepareJavaInterop`.
- `dotnet build src\Xamarin.Android.Build.Tasks\Xamarin.Android.Build.Tasks.csproj -c Debug` — 0 errors (93 pre-existing warnings from `src/Mono.Android/` and generated MCW, unrelated to this change).
- Repo-wide grep for `HostOsName`, `HostOsFlavor`, `HostOsRelease`, `HostCpuCount`, `NdkLlvmTag`, and the MSBuild `MakeConcurrency` property — clean.
- Repo-wide grep for `xaprepare` — clean apart from the five intentional historical breadcrumb comments listed above.

Why
bin/configuration.mk exists only to persist CONFIGURATION=<value> between Unix make invocations. Removing it lets us delete the only meaningful contents of Step_GenerateFiles.Unix.cs, continuing the slow removal of xaprepare (see precedent: #11568, #11529).
What
  • Drop -include bin/configuration.mk from the top of Makefile. The CONFIGURATION ?= Debug fallback at the top of the file is unchanged.
  • Delete build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs entirely (it contained GeneratedConfigurationFile and a one-line AddUnixPostBuildSteps partial that registered it).
The partial void AddUnixPostBuildSteps (Context context, List<GeneratedFile> steps); declaration in Step_GenerateFiles.cs is intentionally left in place — partial methods without an implementation are legal in C#, and the call site becomes a zero-cost no-op. Step_GenerateFiles.Windows.cs implements a different partial (AddOSSpecificSteps) and is unaffected.
Why this is safe
CallerPre-change behaviorPost-change behavior
All CI YAML (build-linux-steps.yaml, build-macos-steps.yaml, commercial-build.yaml, azure-pipelines-apidocs.yaml)Passes CONFIGURATION=$(XA.Build.Configuration) on every make callSame — explicit value still wins
build.sh (make prepare && make jenkins && make pack-dotnet)First make prepare runs against an empty bin/, so the -include no-ops and ?= Debug takes effectIdentical — ?= Debug still takes effect
Fresh local checkout, bare make all?= Debug (no bin/configuration.mk yet)Same
Local dev who runs make prepare CONFIGURATION=Release then bare make allPersisted Release via bin/configuration.mkNow defaults back to Debug — must pass CONFIGURATION=Release on every invocation
That last case is the only behavior change. It was never documented as a contract anywhere in Documentation/ or README.md, and developers building Release locally should be passing the flag explicitly anyway.
Verification
  • git grep "configuration\.mk" and git grep "GeneratedConfigurationFile": zero matches after this change.
  • dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj: 0 warnings, 0 errors.
  • Rubber-duck review: no remaining Path.Combine(..., "configuration.mk") references, no Makefile target depends on bin/configuration.mk as a prerequisite, and the leftover partial-method declaration is benign.

[build] Remove unused bin/configuration.mk
1ad2d35
`bin/configuration.mk` existed only to persist `CONFIGURATION=<value>`
between Unix `make` invocations. CI passes `CONFIGURATION=...` explicitly
on every `make` call, and `build.sh` never sets it (so a fresh checkout
always hit the `CONFIGURATION ?= Debug` default anyway). Dropping the
include lets us delete the only meaningful contents of
`Step_GenerateFiles.Unix.cs`, continuing the slow removal of xaprepare.
- Drop `-include bin/configuration.mk` from the top of `Makefile`. The
`CONFIGURATION ?= Debug` fallback is unchanged.
- Delete `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs`
entirely. The `partial void AddUnixPostBuildSteps (...)` declaration in
`Step_GenerateFiles.cs` is left as a no-op (legal C#); the call site
becomes a zero-cost no-op. `Step_GenerateFiles.Windows.cs` implements a
different partial (`AddOSSpecificSteps`) and is unaffected.

After deleting `Step_GenerateFiles.Unix.cs`, the `partial void
AddUnixPostBuildSteps (...)` declaration and its call site in
`Step_GenerateFiles.cs` were no-ops. Remove them so the file no longer
references a vestige of the `bin/configuration.mk` generator.

[xaprepare] Check inMono.Android.Apis.projitems, remove generator (#…
63951b8
…11608)
`Mono.Android.Apis.projitems` was previously generated at prepare time by
`GeneratedMonoAndroidProjitemsFile` (in xaprepare) from the
`BuildAndroidPlatforms.AllPlatforms` list. Both had exactly one consumer
(each other), so check in the projitems as a source file and drop the
generator plumbing.
Changes:
* Add `src/Mono.Android/Mono.Android.Apis.projitems` — content matches
the generator's output byte-for-byte; only the header comment now
points at `Documentation/workflow/HowToAddNewApiLevel.md` instead of
declaring "GENERATED FILE".
* Repoint the 4 importers (`Mono.Android.targets` x2,
`create-installers.targets`, `create-android-api.csproj`,
`Xamarin.Android.Build.Tasks.targets`) at the new path and drop the
`Condition="Exists(...)"` guards — the file is always present now.
* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* [Xamarin.AndroidTools] Remove dead VS Mac / legacy code (#11607)
Context: after the `android-platform-support` repo was inlined here
(see c22cdcf), `src/Xamarin.AndroidTools/` carries a large amount of
code that was only used by old VS Mac / installer / debugger-host
workflows that are no longer part of the .NET for Android product. None
of these types have callers anywhere in this repo, in
`external/xamarin-android-tools/`, or in `external/Java.Interop/`.
Removed (13 files):
* `PublicationUtilities/PublishAndroidApplication.cs`
* `PublicationUtilities/PackageSigningTasks.cs`
* `PublicationUtilities/KeyManagement.cs`
* `PublicationUtilities/KeystoreEntry.cs`
* `Sessions/AndroidDeploySession.cs`
* `Sessions/AndroidConnectCommandSession.cs`
* `Sessions/AndroidCommandSession.cs`
* `Sessions/AndroidDeploymentException.cs`
* `Devices/AndroidPackageList.cs`
* `Devices/AndroidPackageListExtensions.cs`
* `Debugging/MonoDroidProcessMonitor.cs`
* `PlatformPackage.cs`
* `IProgressNotifier.cs`
* `AndroidSigningOptions.cs`
Moved (still needed by `ProcessUtils.cs`):
* `PublicationUtilities/AndroidSdkToolException.cs` ->
`AndroidSdkToolException.cs` (namespace unchanged)
Pruned from `Devices/AndroidDeviceExtensions.cs` (the methods only
referenced the just-deleted types and had no in-tree callers):
* `StartActivityWithCommandSession` (used `AndroidCommandSession`)
* `GetDeploySession`, `GetPackagesAsync`, `GetPackages` (used
`AndroidDeploySession` / `IProgressNotifier`)
* `InstallSharedRuntime*` and `InstallSharedPlatform*` overloads
that took `IProgressNotifier`
* `GetPackageRemotePath`/`GetPackageRemotePathAsync` (used
`AndroidDeploymentException`)
* `GetFastDevRemotePath`/`GetFastDevRemotePathAsync` and the inner
`FastDevRemotePathInfo` class (only consumer was
`GetPackageRemotePathAsync`)
Kept methods in `AndroidDeviceExtensions.cs` are the ones still used
by `Xamarin.Android.Build.Debugging.Tasks` (`EnsureProperties`,
`KillProcessAndWaitForExit`, `PushAndInstallPackageAsync`) and by
`DebuggingExtensions` (`SetFastDevPropertyFile`, `GetProcessIDAsync`,
`SetDebugPropertiesAsync`).
Also cleaned up:
* `Properties/Resources.resx` (English source): removed seven
`CreateKeyError_*` strings that only `KeyManagement.cs` used.
* `Properties/Resources.Designer.cs`: removed the seven matching
properties.
* `MonoDroidSdk.cs`: two `[Obsolete]` messages referenced the
now-deleted `PlatformPackage`; changed to `"Do not use."`.
Non-English `Resources.*.resx` and `Localize/loc/**/*.lcl` are left
alone per repo policy (auto-regenerated by OneLocBuild).
Build verified locally:
* `src/Xamarin.AndroidTools/Xamarin.AndroidTools.csproj`
* `src/Mono.AndroidTools/Mono.AndroidTools.csproj`
* `src/Xamarin.Android.Build.Debugging.Tasks/Xamarin.Android.Build.Debugging.Tasks.csproj`
* `src/Xamarin.Installer.AndroidSDK/Xamarin.Installer.AndroidSDK.csproj`
Net change: -4225 / +2 lines across 19 files.

* [NUnitLite] Add OneTimeSetUp/OneTimeTearDown attribute shims
NUnit 3.x renamed [TestFixtureSetUp]/[TestFixtureTearDown] to [OneTimeSetUp]/[OneTimeTearDown]. dotnet/java-interop#1437 migrated the Java.Interop test suite to the new names.
The bundled Xamarin.Android.NUnitLite (src-ThirdParty/NUnitLite/) only defines the legacy names. Add no-op subclasses for the new names so test source using [OneTimeSetUp]/[OneTimeTearDown] still compiles against bundled NUnitLite once the Java.Interop submodule is bumped past dotnet/java-interop#1437.
These shims become unnecessary once dotnet/android moves off bundled NUnitLite to stock NUnit (tracked in PR #11224).

[build] Remove Step_PrepareProps; fold values into eng/Versions.props (…
ee0392c
…#11613)
Continues the slow `xaprepare` removal. Recent precedent: #11568 (CopyExtraResultFilesForCI → YAML), #11580 (configuration.mk removal), #11529 (android-platform-support consolidation, which also dropped `Step_PrepareExternalGitDependencies`).
## What
`Step_PrepareProps` generated `external/Java.Interop/Configuration.Override.props` (inside the submodule) by substituting two placeholders into `build-tools/scripts/Configuration.Java.Interop.Override.in.props`. The substituted properties (`_XamarinAndroidCecilVersion`, `UtilityOutputFullPathCoreApps`, `XamarinAndroidToolsDirectory`) are now supplied directly via the checked-in static file `external/Java.Interop.override.props`, which Java.Interop's own `Directory.Build.props` already auto-imports via the parent-dir convention added in dotnet/java-interop#872.
The shared version values (`MonoCecilVersion`, `AndroidPackVersion`, `AndroidPackVersionSuffix`) move into `eng/Versions.props`. `Directory.Build.props` and `external/Java.Interop.override.props` both `<Import>` it. No duplicate-import sentinel is needed because every code path that imports `Configuration.props` has already loaded `Directory.Build.props` (either via MSBuild auto-load or via the explicit `<Import>` in `external/xamarin-android-tools.override.props`).
`MicrosoftAndroidSdkPackName` stays in `Configuration.props` (it is OS-conditioned, not version-shaped, so it doesn't belong in `Versions.props`). The same 3-line OS-conditioned block is mirrored privately in `external/Java.Interop.override.props` as `_MicrosoftAndroidSdkPackName`, used only to compute `UtilityOutputFullPathCoreApps` for the Java.Interop build.
Also dropped:
- `Configurables.Paths.InstallMSBuildDir` and its backing field — the only consumer was `Step_PrepareProps`.
- The dead `UtilityOutputFullPath` line in the old template — Java.Interop's `TargetFrameworkDependentValues.props` unconditionally routes it to `$(UtilityOutputFullPathCoreApps)` anyway, so it was a no-op.
Updated `build-tools/scripts/XAVersionInfo.targets` (the `GitBlame` for `<AndroidPackVersion>` now points at `eng/Versions.props`) and `Documentation/guides/HowToBranch.md` to reflect the moves.
## Why not just `<Import>` `Directory.Build.props` from the Java.Interop override?
That was the original idea. I prototyped it: importing dotnet/android's full props chain from `external/Java.Interop.override.props` flips `DotNetTargetFrameworkVersion` from `10.0` to `11.0` inside Java.Interop, and `dotnet restore Java.Interop.csproj` then fails with:
```
NETSDK1045: The current .NET SDK does not support targeting .NET 11.0
```
`xamarin-android-tools.override.props` gets away with the same trick only because its sole csproj sets `AndroidToolsDisableMultiTargeting=true`, which makes the TFM-clobber harmless. Java.Interop has no equivalent escape hatch.
`eng/Versions.props` is collision-free with Java.Interop (verified against the submodule sources — none of the existing entries collide), has no `<Import>` of its own, and is the safe minimal shared file.
## Verification
On Windows:
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj` — 0 warnings, 0 errors.
- From `src/Xamarin.Android.Build.Tasks/`: `dotnet msbuild --getProperty:MonoCecilVersion,AndroidPackVersion,AndroidPackVersionSuffix,MicrosoftAndroidSdkPackName,MicrosoftAndroidSdkOutDir` — values unchanged from baseline.
- From `external/Java.Interop/src/Java.Interop/`:
- `dotnet msbuild --getProperty:DotNetTargetFramework,_XamarinAndroidCecilVersion,UtilityOutputFullPathCoreApps` returns `net10.0`, `0.11.5`, the expected packs/tools path.
- `dotnet restore Java.Interop.csproj` succeeds (no `NETSDK1045`).

[build] Remove omnisharp.json generation from xaprepare (#11631)
58ccc1f
### Context
`Get_Omnisharp_Json` in `Step_GenerateFiles` substituted two placeholders into `build-tools/scripts/omnisharp.json.in` and wrote `omnisharp.json` at the repo root for OmniSharp / VS Code C# extension users. The generated file was always `.gitignore`d and **nothing in the repo, build, or CI consumes it** — it was purely a local-dev convenience.
Anyone who actually wants an `omnisharp.json` can keep their own local copy (it remains gitignored). Removing this generation slice is another small step in the slow xaprepare reduction, continuing the pattern from #11568, #11580, #11608, and #11613.
### Audit
Before this change `git grep -in "omnisharp"` returned five hits. After it returns only one — the unrelated MSBuild-context guard in `xaprepare.csproj` that prevents xaprepare's targets from importing under OmniSharp's MSBuild process:
```
build-tools/xaprepare/xaprepare/xaprepare.csproj:52:
<Import Project="xaprepare.targets" Condition=" $(MSBuildToolsPath.IndexOf('omnisharp')) < 0 " />
```
That guard is intentional and is **not** touched by this PR.
### Changes
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`: drop the `Get_Omnisharp_Json (context)` entry from the generated-files list and delete the `Get_Omnisharp_Json` method.
- Delete `build-tools/scripts/omnisharp.json.in`.
The shared properties used by the deleted method (`MicrosoftDotnetSdkInternalPackageVersion`, `DotNetPreviewPath`) are still referenced by `Step_InstallDotNetPreview` and `xaprepare.targets`, so they remain.
### Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` — 0 warnings, 0 errors.
- `git grep -in "omnisharp"` — returns only the unrelated `xaprepare.csproj` guard described above.
- No `Documentation/` references to omnisharp; no `.vscode/` folder in the repo.
- Diff: 3 files, 35 deletions, 0 additions.

[xaprepare] Check in Ndk.projitems, remove generator (#11733)
dc54c1c
Mirrors #11608 (which checked in `Mono.Android.Apis.projitems` the same way). See also #11568, #11580, #11613, #11631, #11657, #11658.
## What
`build-tools/scripts/Ndk.projitems.in` was a template with `@NDK_*@` placeholders that the `Get_Ndk_projitems` generator in xaprepare filled in from constants in `BuildAndroidPlatforms.cs`. Those substitution values only change on rare NDK bumps, so generating the file on every build adds no value.
This PR checks in the resolved file as a static `build-tools/scripts/Ndk.projitems` and removes the generator.
## Changes
- **Add** `build-tools/scripts/Ndk.projitems` — the static, checked-in file. Rather than hardcoding values, it sources them from the existing properties in `Configuration.props` (which is imported before `Ndk.targets`):
- `AndroidNdkVersion` → `$(_XAAndroidNdkRelease)`
- `AndroidNdkPkgRevision` → `$(_XAAndroidNdkPkgRevision)`
- the per-ABI `AndroidNdkApiLevel_*` → `$(AndroidMinimumDotNetApiLevel)`
So there is nothing to keep in sync on an NDK/API bump.
- **`build-tools/scripts/Ndk.targets`** — point `ProjitemsFile` at the new in-tree location (`$(MSBuildThisFileDirectory)Ndk.projitems`) instead of `bin/Build$(Configuration)/Ndk.projitems`.
- **Delete** `build-tools/scripts/Ndk.projitems.in`.
- **`Step_GenerateFiles.cs`** — remove the `Get_Ndk_projitems` method and its dispatch entry.
- **`Configurables.cs`** — update a doc comment reference from `Ndk.projitems.in` → `Ndk.projitems`.
### Simplifications (from review)
- **Collapsed the dead legacy/NET API-level split.** The legacy 32-bit minimum API level used to be lower than the .NET minimum, but they are identical now. Removed the two per-ABI properties that nothing references (`AndroidNdkApiLevel_Arm`, `AndroidNdkApiLevel_X86_Legacy`). The `arm64-v8a`/`x86_64` properties are kept because shipped targets (`Build.Tasks.targets`, `Common.props.in`, `NativeAOT.targets`) still consume them by name.
- **Removed the `ApiLevelNET` item metadata.** `ApiLevelNET` was the .NET (.NET 6+) Android minimum API level vs. the legacy Xamarin.Android/Mono `ApiLevel`; the two are identical now and this repo is .NET-only. Its only consumer was `src/native/common/libunwind/libunwind-xamarin.targets`, which now reads `ApiLevel`. Dropped `ApiLevelNET` from all four `AndroidSupportedTargetJitAbi` items.
The NDK constants in `BuildAndroidPlatforms.cs` are intentionally left untouched — they're still consumed by `Get_XABuildConfig_cs` and the cmake presets generator.
## Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 errors / 0 warnings.
- Evaluated the import chain via a standalone MSBuild harness (importing the real `Configuration.props`); it produces all four `AndroidSupportedTargetJitAbi` items with `ApiLevel`=24 and the expected `AndroidRID` metadata, matching prior generator output (NDK `28c` / pkg `28.2.13676358`).
- Audits clean: `git grep Ndk.projitems.in`, `git grep Ndk_projitems`, `git grep ApiLevelNET`, and the old `bin/Build$(Configuration)/Ndk.projitems` path all return 0 hits.

[xaprepare] Remove unused tool runners and helper classes (#11740)
185bf46
Many xaprepare provisioning steps have been removed over the past year (#11332, #11348, #11399, #11440, #11441, #11636 and follow-up cleanups in #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737). The supporting scaffolding around those steps was left behind. This PR removes the verified-dead pieces in two passes.
## Files removed (first pass — original audit)
| File | Justification |
| --- | --- |
| `Application/TestAssembly.cs` | Orphan test infra; only referenced by `TestAssemblyType.cs`. |
| `Application/TestAssemblyType.cs` | Only referenced by `TestAssembly.cs`. |
| `Application/StepWithDownloadProgress.cs` | No subclasses remain. |
| `Application/NDKTool.cs` | NDK provisioning moved to MSBuild in #11440. Last consumer was the also-dead `Configurables.NDKTools` collection (removed below). |
| `ToolRunners/SnRunner.cs` | Strong-naming tool runner; never instantiated. |
| `ToolRunners/SnRunner.OutputSink.cs` | Partial sibling of `SnRunner`. |
| `ToolRunners/CMakeRunner.cs` | Never instantiated. |
| `ToolRunners/CMakeRunner.OutputSink.cs` | Partial sibling of `CMakeRunner`. |
## Files removed (second pass — repo-wide re-audit)
| File | Justification |
| --- | --- |
| `ToolRunners/MakeRunner.Linux.cs` | Partial of `MakeRunner`; type never instantiated. |
| `ToolRunners/MakeRunner.MacOS.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.OutputSink.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MSBuildRunner.cs` | Never instantiated. |
| `ToolRunners/MSBuildRunner.OutputSink.cs` | Partial sibling of `MSBuildRunner`. |
| `ToolRunners/NinjaRunner.cs` | Never instantiated. |
| `ToolRunners/NinjaRunner.OutputSink.cs` | Partial sibling of `NinjaRunner`. |
| `Application/ScenarioNoStandardEndSteps.cs` | Abstract class with zero subclasses. |
## Cascading cleanup
- `ConfigAndData/Configurables.cs` — removed the dead `NDKTools` `List<NDKTool>` collection (lines 132–145). Rest of the file unchanged.
## Removed from initial deletion list after verification
- `Application/Extensions.DictionaryOfProgramVersionParser.cs` — initial name-only audit flagged it as dead, but its `Add` extension method is consumed via dictionary collection-initializer syntax in `Application/VersionFetchers.cs`. The consumer never references the static class by name, which is why the first audit missed it. The file stays.
- `Scenarios/Scenario_Required.cs` — looks unreferenced by static grep, but `Scenario` subclasses are reflectively discovered via the `[Scenario]` attribute in `Context.cs` (`Utilities.GetTypesWithCustomAttribute<ScenarioAttribute> ()`). Live. The file stays.
## Verification
- `git grep -n -w <TypeName>` for each deleted type now returns 0 real hits (only unrelated `"TestAssembly"` string literals in `tests/Microsoft.Android.Sdk.TrimmableTypeMap.Tests/` remain — those are assembly-name strings, not the C# type).
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 warnings, 0 errors.
## Deferred follow-up
The csproj conditionally excludes `*MacOS*` files from compilation when `HostOS != Darwin`, so static dead-code analysis from a Windows/Linux host can't see whether the macOS-only consumers are themselves live. These candidates need verification on a Mac host (or a build matrix) before deletion:
- `Application/PkgProgram.MacOS.cs`
- `Application/HomebrewProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
- `ConfigAndData/Dependencies/MacOS.cs`

[xaprepare] Move CMake file generation into a dedicated MSBuild proje…
5e9346d
…ct (#11760)
Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.
## What changes
Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:
* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.
Both are now generated by a new project:
* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.
### Why a dedicated project (not just a target in `native.targets`)
The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:
* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).
A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.
### Incremental correctness
`_GenerateCMakeFiles` declares fully-anchored `Inputs`:
* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)
so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)
### Cascading deletions in xaprepare
* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.
`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).
### What stays
The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.
## Verification
On Windows:
* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors
Incremental behaviour verified by walking through MSBuild diagnostic output:
* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.
The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.

[xaprepare] Remove vestigial OS dependency provisioning (#11803)
e89fded
### Context
After #11636 (dotnet provisioning step removed) and #11731 (test-deps scenarios removed), `Context.AutoProvision` is `false` by default everywhere except hand-run dev provisioning, which is no longer in use. The per-OS package lists are populated at `OS.Init()` time but `EnsureDependencies` is effectively a no-op:
- `OS.EnsureDependencies()` returns early when `AutoProvision` is false (the default),
- nothing else in the codebase reads from the `Program` derivatives' install/uninstall paths,
- the `BuildToolsInventory` writer remains driven only from `EssentialTools.MacOS.cs` (homebrew version detection).
The `OS.Init() / InitializeDependencies() / EnsureDependencies()` machinery on `OS.cs` itself is intentionally **left in place** here — that's a larger refactor for a follow-up PR. This PR only strips the now-vestigial package-list data and the program/runner classes that fed it.
### Files deleted (Phase F — macOS, 4 files)
- `Application/HomebrewProgram.MacOS.cs`
- `Application/PkgProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
### Files deleted (Phase G — Linux, 5 files)
- `Application/Program.Linux.cs` (`LinuxProgram` base — orphan after subclasses go)
- `Application/Program.ArchLinux.cs`
- `Application/Program.DebianLinux.cs`
- `Application/Program.FedoraLinux.cs`
- `Application/Program.GentooLinux.cs`
### Files deleted (Phase 3 — orphan)
- `Application/IBuildInventoryItem.cs` (only implementor was `HomebrewProgram`; `BuildToolsInventory` itself stays, populated directly by `EssentialTools.MacOS.cs`).
### Files reduced to empty stubs
`ConfigAndData/Dependencies/`:
- `MacOS.cs` — `InitializeDependencies()` no-op (was Homebrew formula list + git fallback).
- `Linux.Arch.cs` — class kept (referenced by `distroMap`); package list removed.
- `Linux.Fedora.cs` — same.
- `Linux.Gentoo.cs` — same.
- `Linux.DebianCommon.cs` — common Debian/Ubuntu package list removed; `Flavor = "Debian"` kept.
- `Linux.UbuntuCommon.cs` — `libtoolPackages` + `NeedLibtool` virtual + `InitOS` override removed (all dead).
- `Linux.Debian.cs` — all per-version package lists (`packages`, `packagesPre10`, `packagesPreTrixie`, `packagesTrixieAndLater`, `packages10AndNewerBuildBots`) removed; release/codename detection (`EnsureVersionInformation`, `DebianUnstableVersionMap`, `IsDebian10OrNewer`, etc.) preserved as conservative scope.
- `Linux.Ubuntu.cs` — `preCosmicPackages`, `cosmicPackages`, `preDiscoPackages` lists + `NeedLibtool` override removed; `UbuntuRelease` + `EnsureVersionInformation` preserved.
- `Linux.Mint.cs` — `NeedLibtool` override removed (the property is gone from the base).
`ConfigAndData/Dependencies/Windows.cs` was already a no-op stub — no edit.
### Verification
Orphan audit (each `git grep -nw <Type> -- 'build-tools/xaprepare/*'` reports **0 hits**):
- `HomebrewProgram`, `PkgProgram`, `BrewRunner`, `PkgutilRunner`
- `ArchLinuxProgram`, `DebianLinuxProgram`, `FedoraLinuxProgram`, `GentooLinuxProgram`, `LinuxProgram`
- `IBuildInventoryItem`
Build:
```
dotnet build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug
Build succeeded. 0 Warning(s) 0 Error(s)
```
### Out of scope (follow-up)
- Removing the abstract `OS.InitializeDependencies()` declaration and the surrounding `EnsureDependencies()` machinery from `OperatingSystems/OS.cs`.
- `VersionFetchers` / `ProgramVersionParser` / `RegexProgramVersionParser` / `SevenZipVersionParser` / `Extensions.DictionaryOfProgramVersionParser.cs` are kept — `Utilities.GetProgramVersion` still queries them from `Program.cs`, `ToolRunner.cs`, `EssentialTools.MacOS.cs`, and `OperatingSystems/MacOS.cs` (brew detection).
### Precedent
#11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740, #11760

[xaprepare] Move XABuildConfig generation to AndroidBuildConfig.dll (#…
788d363
…11826)
## Summary
Moves `XABuildConfig.cs` generation out of `xaprepare` and into a new strong-named class library at `src/AndroidBuildConfig/AndroidBuildConfig.csproj` that produces `AndroidBuildConfig.dll`.
This continues the incremental removal of `xaprepare`, following the precedent set by `cmake-config.csproj` (#11760) and the recent batch #11568, #11580, #11608, #11613, #11631, #11731, #11732, #11733, #11737, #11740, #11803, #11821, #11825.
It also fixes a long-standing wart: previously `XABuildConfig.cs` was `<Compile Include>`'d into three different assemblies (`Xamarin.Android.Build.Tasks`, `Xamarin.ProjectTools`, and `Xamarin.Android.Build.Tests`), so every test that mentioned `XABuildConfig` produced a `CS0436` "type conflicts with imported type" warning — about **22** of them.
Wrapping the type in its own assembly collapses it to a single definition that every consumer references normally. After this change `Xamarin.Android.Build.Tests` builds with **7** warnings (none for `XABuildConfig`).
## How it works
`src/AndroidBuildConfig/AndroidBuildConfig.csproj`:
- `Microsoft.NET.Sdk` / `netstandard2.0`, strong-named with `product.snk`.
- `ProjectReference`s `Xamarin.Android.Tools.AndroidSdk` (for the `AndroidTargetArch` enum used by the template).
- `<UsingTask>`s `ReplaceFileContents`, `GitCommitHash`, and `GitBranch` from `$(PrepTasksAssembly)`, all with `TaskFactory="TaskHostFactory" Runtime="NET"` per repo convention.
- The `_GenerateXABuildConfig` target runs `BeforeTargets="BeforeCompile;CoreCompile"`, computes every substitution from MSBuild properties already exposed by `Configuration.props` (NDK major/minor/micro via `$(_XAAndroidNdkPkgRevision.Split('.'))`, API levels via `Split`/`Contains`, full commit hash via `GitCommitHash.CommitHash`, branch via `GitBranch.Branch`), and writes the file to `$(IntermediateOutputPath)XABuildConfig.cs`. The `<Compile Include>` lives inside the target so it resolves at execution time, when `IntermediateOutputPath` is final.
- `XABuildConfig` is now `public static class` instead of `internal static class`.
The three consumer csprojs lose their `<Compile Include="…XABuildConfig.cs" />` and now have a normal `<ProjectReference Include="…AndroidBuildConfig.csproj" />` (no `ReferenceOutputAssembly="False"`).
`build-tools/installers/create-installers.targets` ships `AndroidBuildConfig.dll` + `.pdb` alongside `Xamarin.Android.Build.Tasks.dll`.
## xaprepare cleanup
Removed dead code that only existed to feed the old `Get_XABuildConfig_cs` step:
- `Step_GenerateFiles.Get_XABuildConfig_cs` and its `GetMajor` / `GetMinor` locals
- `BuildInfo`: `NDKRevision`, `NDKVersionMajor`, `NDKVersionMinor`, `NDKVersionMicro`, `NDKVersion`, `XACommitHash`, `XABranch`, `GatherGitInfo`, `DetermineXACommitInfo`, `cachedNdkVersion`
- `Context`: the `if (SelectedScenario.NeedsGitBuildInfo) { await BuildInfo.GatherGitInfo … }` block
- `Scenario.NeedsGitBuildInfo` (and the `NeedsGitBuildInfo = true;` setters in `Scenario_Standard` and `Scenario_Required`)
- `BuildAndroidPlatforms.cs` — entire file (only contained constants used by the deleted code)
- `Utilities.ParseAndroidPkgRevision`
- `GitRunner.GetTopCommitHash` and `GitRunner.GetBranchName` (class retained — still used by `BuildInfo.DetermineLastVersionChangeCommit`)
## Files
**Added**
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
**Renamed/moved**
- `build-tools/scripts/XABuildConfig.cs.in` → `src/AndroidBuildConfig/XABuildConfig.cs.in` (`static class` → `public static class`)
**Modified**
- `src/Xamarin.Android.Build.Tasks/Xamarin.Android.Build.Tasks.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.ProjectTools/Xamarin.ProjectTools.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Xamarin.Android.Build.Tests.csproj`
- `build-tools/installers/create-installers.targets`
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`
- `build-tools/xaprepare/xaprepare/Application/BuildInfo.cs`
- `build-tools/xaprepare/xaprepare/Application/Context.cs`
- `build-tools/xaprepare/xaprepare/Application/Scenario.cs`
- `build-tools/xaprepare/xaprepare/Application/Utilities.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Standard.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Required.cs`
- `build-tools/xaprepare/xaprepare/ToolRunners/GitRunner.cs`
- `build-tools/xaprepare/README.md`
**Deleted**
- `build-tools/xaprepare/xaprepare/ConfigAndData/BuildAndroidPlatforms.cs`
## Verification
- `AndroidBuildConfig.csproj`: 0 warnings, 0 errors.
- `Xamarin.Android.Build.Tasks.csproj`: 0 errors, 85 pre-existing unrelated warnings (none for `XABuildConfig`).
- `Xamarin.Android.Build.Tests.csproj`: 0 errors, **7** warnings — down from ~22; all `CS0436 XABuildConfig` conflicts eliminated.
- `xaprepare.csproj`: 0 warnings, 0 errors.
- Generated `XABuildConfig.cs` is semantically identical to the pre-change xaprepare output. The only token difference is the intentional `static class` → `public static class`; everything else (NDK split, API-level major/minor split, supported-ABIs semicolon list, full commit hash, branch name, etc.) matches the previous baseline byte-for-byte.

[xaprepare] Move cgmanifest.json generation from xaprepare to YAML (#…
c7c9458
…11825)
Continues the incremental removal of `xaprepare` by moving the
`cgmanifest.json` generator out of the C# step
`Step_GenerateCGManifest` and into a YAML `pwsh:` step that runs only
on CI.
The file is consumed exclusively by the Azure DevOps Component
Governance Detection task (auto-injected on internal pipelines by
`eng/common/core-templates/job/job.yml`). It is not consumed by any
in-repo build target, so generating it from the C# Prepare step is no
longer necessary.
We cannot drop the file outright: `eng/common` ships CG infrastructure
but it is not yet wired to auto-discover submodules in our pipelines,
so the explicit `cgmanifest.json` is still the source of truth.
Files:
* Added: `build-tools/automation/yaml-templates/generate-cgmanifest.yaml`
* Modified: `build-windows-steps.yaml`, `build-macos-steps.yaml`,
`build-linux-steps.yaml`, `commercial-build.yaml` (call the new
template after the Prepare/`make jenkins` step)
* Modified: `Scenario_Standard.cs` (drop registration)
* Modified: `GitRunner.cs` (remove now-unused `ConfigList` and
`SubmoduleStatus` methods)
* Deleted: `Step_GenerateCGManifest.cs`
Verification: byte-for-byte diff of the YAML-generated
`cgmanifest.json` against the previous C# output on Debug:
Baseline=3144 New=3144
Total byte differences: 0
Precedent PRs in this stream: #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803,
#11821.
### Simplify generate-cgmanifest.yaml using ConvertTo-Json
Replace the hand-rolled StringBuilder JSON emission with PowerShell's
`ConvertTo-Json`. The output is no longer byte-identical to the
previous C# output (2-space indent instead of 4, and slightly
different whitespace), but it is still valid JSON matching the
component-detection-manifest schema. The Azure DevOps Component
Governance Detection task parses the file, so formatting does not
matter.

[xaprepare] Delete redundant Windows JdkInfo.props generator (#11946)
e18dc17
On Windows, xaprepare's Step_GenerateFiles.Windows.cs writes
external/Java.Interop/bin/Build$(Configuration)/JdkInfo.props from
build-tools/xaprepare/xaprepare/Resources/JdkInfo.Windows.props.in.
But this file is immediately overwritten. The PrepareWindows.targets
Prepare flow runs, in order:
1. `dotnet xaprepare -a` — writes JdkInfo.props (this code).
2. `MSBuild Xamarin.Android.BootstrapTasks.sln` — does not read JdkInfo.props.
3. `MSBuild src/workloads/workloads.csproj` — does not read JdkInfo.props.
4. `CallTarget PrepareJavaInterop` → `dotnet build -t:Prepare Java.Interop.sln`
→ external/Java.Interop/build-tools/scripts/Prepare.targets → runs the
`JdkInfo` MSBuild task → overwrites JdkInfo.props with its own generated
content.
Nothing between step 1 and step 4 reads the file, and Java.Interop's Prepare
always regenerates it. Now that external/Java.Interop is in-tree, we can
safely delete the redundant write.
This is the smallest-diff removal:
* Delete Step_GenerateFiles.Windows.cs (the AddOSSpecificSteps partial).
* Delete Resources/JdkInfo.Windows.props.in.
* In Step_GenerateFiles.cs, drop the `partial void AddOSSpecificSteps`
declaration and collapse GetFilesToGenerate so `atBuildStart == false`
returns null. Ctor surface (atBuildStart, onlyRequired) is unchanged so
Scenario_Required.cs is unaffected.
* In Scenario_Standard.cs, remove the AddEndSteps override — the only
thing it did was schedule the now-empty Step_GenerateFiles(atBuildStart:
false).
Preserved (future slices will address these):
* Get_Configuration_OperatingSystem_props (D1).
* OperatingSystems/*.cs and Context.OS.* surface.
* PrepareWindows.targets, DotNet.targets, Java.Interop's Prepare.targets.
Verification:
* dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug
→ Build succeeded. 0 Warning(s). 0 Error(s).
* build.cmd -t:Prepare -c Debug (Windows, cold tree) → succeeds; the file
external/Java.Interop/bin/BuildDebug/JdkInfo.props exists.
* Compare-Object of the resulting JdkInfo.props before vs after this
change → byte-identical (1493 bytes, SHA256
DE59A8061B7657831788FFED7BC1DEECA442E9181605083A4553DE7AC8C003A1),
confirming Java.Interop's overwrite is what always ends up on disk.
* Grep audit under build-tools/xaprepare/: no remaining references to
Step_GenerateFiles.Windows, JdkInfo.Windows.props.in, or
AddOSSpecificSteps.

[xaprepare] Delete Configuration.OperatingSystem.props generator and …
be5272c
…xaprepare project (#11959)
Follow-up to #11956, which moved the JDK half of `Configuration.OperatingSystem.props` to Java.Interop's `JdkInfo.props`. The remaining NDK / OS-info half has zero real consumers, so this PR:
1. Deletes the last generator template (`Configuration.OperatingSystem.props.in`).
2. Cascades through `Step_GenerateFiles`, both `Scenario_*` classes (which now had zero steps), and every supporting `OperatingSystems/`, `Context.*OS.cs`, `EssentialTools.*`, `ToolRunners/*`, `Configurables.*`, `Application/*`, and `Main.cs` file that only existed to feed the scenarios.
3. Deletes the whole `build-tools/xaprepare/` project.
4. Patches every integration point (`Makefile`, `PrepareWindows.targets`, `BuildEverything.mk`, CI YAML, docs) so `build.cmd -t:Prepare` and `make prepare` still work end-to-end.
## `Configuration.OperatingSystem.props.in` placeholder audit
| Placeholder | Consumers outside the `.in` file | Action |
| --- | --- | --- |
| `HostOsName` | none | drop |
| `HostOsFlavor` | none | drop |
| `HostOsRelease` | none | drop |
| `HostBits` | none (`ArchiveBase.HostBits` in `src/Xamarin.Installer.AndroidSDK/` is an unrelated C# property) | drop |
| `NdkLlvmTag` | none (the NDK toolchain OS tag is resolved elsewhere via `_NdkToolchainOSTag` in `androidsdk.targets`) | drop |
| `HostCpuCount` | only `Configuration.props:72` via `$(MakeConcurrency)` | drop |
## `$(MakeConcurrency)` audit
The only definition was `Configuration.props:72`. A repo-wide grep of `.targets`, `.props`, `.projitems`, `Makefile`, and `.mk` files found zero consumers of the MSBuild property. The `MakeConcurrency` hits under `build-tools/xaprepare/` were an unrelated C# `Context.MakeConcurrency` property.
**Result:** dropped the `MakeConcurrency` MSBuild property entirely (no `$([System.Environment]::ProcessorCount)` replacement needed) and removed the `$(MakeConcurrency)` bullet in `Documentation/building/configuration.md`.
## xaprepare integration audit (grep-confirmed, patched here)
| Location | Change |
| --- | --- |
| `build-tools/xaprepare/` (entire tree) | **deleted** — 86 tracked files |
| `Configuration.props` | dropped `<Import>` of the generated OS props, dropped `MakeConcurrency`, tidied the "between xaprepare and package creation tools" comment |
| `.gitignore` | dropped `Configuration.OperatingSystem.props` |
| `build-tools/scripts/PrepareWindows.targets` | removed `_XAPrepareExe`, `_XAPrepareStandardArgs`, `_BuildXAPrepare` target, and the `Exec dotnet $(_XAPrepareExe)` line. Repointed `Prepare` at `_InstallDotNet`. Kept the space-in-path guard, BootstrapTasks / workloads MSBuilds, and `PrepareJavaInterop` |
| `Makefile` | dropped `PREPARE_PROJECT`, `PREPARE_NET_FX`, `PREPARE_ARGS`, `PREPARE_MSBUILD_FLAGS`, `PREPARE_SCENARIO`, `PREPARE_CI_PR`, `PREPARE_CI`, `_PREPARE_CI_MODE_*`, `_PREPARE_ARGS`, and all their conditionals. Dropped the `dotnet run --project xaprepare.csproj` line from `prepare`. Deleted the `prepare-help` target |
| `build-tools/scripts/BuildEverything.mk` | `jenkins` no longer branches on `PREPARE_CI_PR`/`PREPARE_CI`; just `$(MAKE) prepare && $(MAKE) leeroy` |
| `.github/workflows/copilot-setup-steps.yml` | dropped now-unused `PREPARE_CI=1` |
| `build-tools/automation/azure-pipelines-apidocs.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-linux-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-macos-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/commercial-build.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/copy-extra-result-files.yaml` | dropped `**/Configuration.OperatingSystem.props` glob and the stale `Step_CopyExtraResultFilesForCI` xaprepare-step comment |
| `build-tools/automation/yaml-templates/generate-cgmanifest.yaml` | dropped the stale `Step_GenerateCGManifest` xaprepare-step comment |
| `build-tools/automation/yaml-templates/setup-jdk-variables.yaml` | renamed `$xaPrepareJdkPath` → `$xaJdkPath` for hygiene |
| `Documentation/workflow/HowToAddNewApiLevel.md` | rewrote the "Add New Platform" section to point at `<_PlatformPackage>` entries in `src/androidsdk/androidsdk.targets` instead of `AndroidToolchain.cs`; updated the `--android-sdk-platforms=all` recipe to `dotnet-local build src/androidsdk/androidsdk.csproj -p:AndroidSdkPlatforms=all` |
| `Documentation/building/unix/dependencies.md` | JDK-version link now points at `$(MicrosoftOpenJDKVersion)` in `/Configuration.props` instead of the deleted `Configurables.cs` |
| `Documentation/building/configuration.md` | removed the `$(MakeConcurrency)` bullet |
**Historical breadcrumb comments left as-is** (still accurate and useful for git-archaeology):
- `.github/skills/update-tpn/SKILL.md`
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
- `src/androidsdk/androidsdk.targets`
- `src/native/cmake-config/cmake-config.csproj`
- `src/workloads/workloads.csproj`
## Verification
- `build.cmd Prepare` — succeeded end-to-end on Windows (0 warnings, 0 errors). The trimmed `Prepare` target ran through `_InstallDotNet`, the space-in-path guard, `Xamarin.Android.BootstrapTasks.sln`, `src/workloads/workloads.csproj`, and `PrepareJavaInterop`.
- `dotnet build src\Xamarin.Android.Build.Tasks\Xamarin.Android.Build.Tasks.csproj -c Debug` — 0 errors (93 pre-existing warnings from `src/Mono.Android/` and generated MCW, unrelated to this change).
- Repo-wide grep for `HostOsName`, `HostOsFlavor`, `HostOsRelease`, `HostCpuCount`, `NdkLlvmTag`, and the MSBuild `MakeConcurrency` property — clean.
- Repo-wide grep for `xaprepare` — clean apart from the five intentional historical breadcrumb comments listed above.

Why
bin/configuration.mk exists only to persist CONFIGURATION=<value> between Unix make invocations. Removing it lets us delete the only meaningful contents of Step_GenerateFiles.Unix.cs, continuing the slow removal of xaprepare (see precedent: #11568, #11529).
What
  • Drop -include bin/configuration.mk from the top of Makefile. The CONFIGURATION ?= Debug fallback at the top of the file is unchanged.
  • Delete build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs entirely (it contained GeneratedConfigurationFile and a one-line AddUnixPostBuildSteps partial that registered it).
The partial void AddUnixPostBuildSteps (Context context, List<GeneratedFile> steps); declaration in Step_GenerateFiles.cs is intentionally left in place — partial methods without an implementation are legal in C#, and the call site becomes a zero-cost no-op. Step_GenerateFiles.Windows.cs implements a different partial (AddOSSpecificSteps) and is unaffected.
Why this is safe
CallerPre-change behaviorPost-change behavior
All CI YAML (build-linux-steps.yaml, build-macos-steps.yaml, commercial-build.yaml, azure-pipelines-apidocs.yaml)Passes CONFIGURATION=$(XA.Build.Configuration) on every make callSame — explicit value still wins
build.sh (make prepare && make jenkins && make pack-dotnet)First make prepare runs against an empty bin/, so the -include no-ops and ?= Debug takes effectIdentical — ?= Debug still takes effect
Fresh local checkout, bare make all?= Debug (no bin/configuration.mk yet)Same
Local dev who runs make prepare CONFIGURATION=Release then bare make allPersisted Release via bin/configuration.mkNow defaults back to Debug — must pass CONFIGURATION=Release on every invocation
That last case is the only behavior change. It was never documented as a contract anywhere in Documentation/ or README.md, and developers building Release locally should be passing the flag explicitly anyway.
Verification

[build] Remove unused bin/configuration.mk
1ad2d35
`bin/configuration.mk` existed only to persist `CONFIGURATION=<value>`
between Unix `make` invocations. CI passes `CONFIGURATION=...` explicitly
on every `make` call, and `build.sh` never sets it (so a fresh checkout
always hit the `CONFIGURATION ?= Debug` default anyway). Dropping the
include lets us delete the only meaningful contents of
`Step_GenerateFiles.Unix.cs`, continuing the slow removal of xaprepare.
- Drop `-include bin/configuration.mk` from the top of `Makefile`. The
`CONFIGURATION ?= Debug` fallback is unchanged.
- Delete `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs`
entirely. The `partial void AddUnixPostBuildSteps (...)` declaration in
`Step_GenerateFiles.cs` is left as a no-op (legal C#); the call site
becomes a zero-cost no-op. `Step_GenerateFiles.Windows.cs` implements a
different partial (`AddOSSpecificSteps`) and is unaffected.

Drop now-dead AddUnixPostBuildSteps partial
5a770f4
After deleting `Step_GenerateFiles.Unix.cs`, the `partial void
AddUnixPostBuildSteps (...)` declaration and its call site in
`Step_GenerateFiles.cs` were no-ops. Remove them so the file no longer
references a vestige of the `bin/configuration.mk` generator.

[xaprepare] Check inMono.Android.Apis.projitems, remove generator (#…
63951b8
…11608)
`Mono.Android.Apis.projitems` was previously generated at prepare time by
`GeneratedMonoAndroidProjitemsFile` (in xaprepare) from the
`BuildAndroidPlatforms.AllPlatforms` list. Both had exactly one consumer
(each other), so check in the projitems as a source file and drop the
generator plumbing.
Changes:
* Add `src/Mono.Android/Mono.Android.Apis.projitems` — content matches
the generator's output byte-for-byte; only the header comment now
points at `Documentation/workflow/HowToAddNewApiLevel.md` instead of
declaring "GENERATED FILE".
* Repoint the 4 importers (`Mono.Android.targets` x2,
`create-installers.targets`, `create-android-api.csproj`,
`Xamarin.Android.Build.Tasks.targets`) at the new path and drop the
`Condition="Exists(...)"` guards — the file is always present now.
* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* [Xamarin.AndroidTools] Remove dead VS Mac / legacy code (#11607)
Context: after the `android-platform-support` repo was inlined here
(see c22cdcf), `src/Xamarin.AndroidTools/` carries a large amount of
code that was only used by old VS Mac / installer / debugger-host
workflows that are no longer part of the .NET for Android product. None
of these types have callers anywhere in this repo, in
`external/xamarin-android-tools/`, or in `external/Java.Interop/`.
Removed (13 files):
* `PublicationUtilities/PublishAndroidApplication.cs`
* `PublicationUtilities/PackageSigningTasks.cs`
* `PublicationUtilities/KeyManagement.cs`
* `PublicationUtilities/KeystoreEntry.cs`
* `Sessions/AndroidDeploySession.cs`
* `Sessions/AndroidConnectCommandSession.cs`
* `Sessions/AndroidCommandSession.cs`
* `Sessions/AndroidDeploymentException.cs`
* `Devices/AndroidPackageList.cs`
* `Devices/AndroidPackageListExtensions.cs`
* `Debugging/MonoDroidProcessMonitor.cs`
* `PlatformPackage.cs`
* `IProgressNotifier.cs`
* `AndroidSigningOptions.cs`
Moved (still needed by `ProcessUtils.cs`):
* `PublicationUtilities/AndroidSdkToolException.cs` ->
`AndroidSdkToolException.cs` (namespace unchanged)
Pruned from `Devices/AndroidDeviceExtensions.cs` (the methods only
referenced the just-deleted types and had no in-tree callers):
* `StartActivityWithCommandSession` (used `AndroidCommandSession`)
* `GetDeploySession`, `GetPackagesAsync`, `GetPackages` (used
`AndroidDeploySession` / `IProgressNotifier`)
* `InstallSharedRuntime*` and `InstallSharedPlatform*` overloads
that took `IProgressNotifier`
* `GetPackageRemotePath`/`GetPackageRemotePathAsync` (used
`AndroidDeploymentException`)
* `GetFastDevRemotePath`/`GetFastDevRemotePathAsync` and the inner
`FastDevRemotePathInfo` class (only consumer was
`GetPackageRemotePathAsync`)
Kept methods in `AndroidDeviceExtensions.cs` are the ones still used
by `Xamarin.Android.Build.Debugging.Tasks` (`EnsureProperties`,
`KillProcessAndWaitForExit`, `PushAndInstallPackageAsync`) and by
`DebuggingExtensions` (`SetFastDevPropertyFile`, `GetProcessIDAsync`,
`SetDebugPropertiesAsync`).
Also cleaned up:
* `Properties/Resources.resx` (English source): removed seven
`CreateKeyError_*` strings that only `KeyManagement.cs` used.
* `Properties/Resources.Designer.cs`: removed the seven matching
properties.
* `MonoDroidSdk.cs`: two `[Obsolete]` messages referenced the
now-deleted `PlatformPackage`; changed to `"Do not use."`.
Non-English `Resources.*.resx` and `Localize/loc/**/*.lcl` are left
alone per repo policy (auto-regenerated by OneLocBuild).
Build verified locally:
* `src/Xamarin.AndroidTools/Xamarin.AndroidTools.csproj`
* `src/Mono.AndroidTools/Mono.AndroidTools.csproj`
* `src/Xamarin.Android.Build.Debugging.Tasks/Xamarin.Android.Build.Debugging.Tasks.csproj`
* `src/Xamarin.Installer.AndroidSDK/Xamarin.Installer.AndroidSDK.csproj`
Net change: -4225 / +2 lines across 19 files.

* [NUnitLite] Add OneTimeSetUp/OneTimeTearDown attribute shims
NUnit 3.x renamed [TestFixtureSetUp]/[TestFixtureTearDown] to [OneTimeSetUp]/[OneTimeTearDown]. dotnet/java-interop#1437 migrated the Java.Interop test suite to the new names.
The bundled Xamarin.Android.NUnitLite (src-ThirdParty/NUnitLite/) only defines the legacy names. Add no-op subclasses for the new names so test source using [OneTimeSetUp]/[OneTimeTearDown] still compiles against bundled NUnitLite once the Java.Interop submodule is bumped past dotnet/java-interop#1437.
These shims become unnecessary once dotnet/android moves off bundled NUnitLite to stock NUnit (tracked in PR #11224).

@jonathanpeppers
[build] Remove Step_PrepareProps; fold values into eng/Versions.props (…
ee0392c
…#11613)
Continues the slow `xaprepare` removal. Recent precedent: #11568 (CopyExtraResultFilesForCI → YAML), #11580 (configuration.mk removal), #11529 (android-platform-support consolidation, which also dropped `Step_PrepareExternalGitDependencies`).
## What
`Step_PrepareProps` generated `external/Java.Interop/Configuration.Override.props` (inside the submodule) by substituting two placeholders into `build-tools/scripts/Configuration.Java.Interop.Override.in.props`. The substituted properties (`_XamarinAndroidCecilVersion`, `UtilityOutputFullPathCoreApps`, `XamarinAndroidToolsDirectory`) are now supplied directly via the checked-in static file `external/Java.Interop.override.props`, which Java.Interop's own `Directory.Build.props` already auto-imports via the parent-dir convention added in dotnet/java-interop#872.
The shared version values (`MonoCecilVersion`, `AndroidPackVersion`, `AndroidPackVersionSuffix`) move into `eng/Versions.props`. `Directory.Build.props` and `external/Java.Interop.override.props` both `<Import>` it. No duplicate-import sentinel is needed because every code path that imports `Configuration.props` has already loaded `Directory.Build.props` (either via MSBuild auto-load or via the explicit `<Import>` in `external/xamarin-android-tools.override.props`).
`MicrosoftAndroidSdkPackName` stays in `Configuration.props` (it is OS-conditioned, not version-shaped, so it doesn't belong in `Versions.props`). The same 3-line OS-conditioned block is mirrored privately in `external/Java.Interop.override.props` as `_MicrosoftAndroidSdkPackName`, used only to compute `UtilityOutputFullPathCoreApps` for the Java.Interop build.
Also dropped:
- `Configurables.Paths.InstallMSBuildDir` and its backing field — the only consumer was `Step_PrepareProps`.
- The dead `UtilityOutputFullPath` line in the old template — Java.Interop's `TargetFrameworkDependentValues.props` unconditionally routes it to `$(UtilityOutputFullPathCoreApps)` anyway, so it was a no-op.
Updated `build-tools/scripts/XAVersionInfo.targets` (the `GitBlame` for `<AndroidPackVersion>` now points at `eng/Versions.props`) and `Documentation/guides/HowToBranch.md` to reflect the moves.
## Why not just `<Import>` `Directory.Build.props` from the Java.Interop override?
That was the original idea. I prototyped it: importing dotnet/android's full props chain from `external/Java.Interop.override.props` flips `DotNetTargetFrameworkVersion` from `10.0` to `11.0` inside Java.Interop, and `dotnet restore Java.Interop.csproj` then fails with:
```
NETSDK1045: The current .NET SDK does not support targeting .NET 11.0
```
`xamarin-android-tools.override.props` gets away with the same trick only because its sole csproj sets `AndroidToolsDisableMultiTargeting=true`, which makes the TFM-clobber harmless. Java.Interop has no equivalent escape hatch.
`eng/Versions.props` is collision-free with Java.Interop (verified against the submodule sources — none of the existing entries collide), has no `<Import>` of its own, and is the safe minimal shared file.
## Verification
On Windows:
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj` — 0 warnings, 0 errors.
- From `src/Xamarin.Android.Build.Tasks/`: `dotnet msbuild --getProperty:MonoCecilVersion,AndroidPackVersion,AndroidPackVersionSuffix,MicrosoftAndroidSdkPackName,MicrosoftAndroidSdkOutDir` — values unchanged from baseline.
- From `external/Java.Interop/src/Java.Interop/`:
- `dotnet msbuild --getProperty:DotNetTargetFramework,_XamarinAndroidCecilVersion,UtilityOutputFullPathCoreApps` returns `net10.0`, `0.11.5`, the expected packs/tools path.
- `dotnet restore Java.Interop.csproj` succeeds (no `NETSDK1045`).

@jonathanpeppers
[build] Remove omnisharp.json generation from xaprepare (#11631)
58ccc1f
### Context
`Get_Omnisharp_Json` in `Step_GenerateFiles` substituted two placeholders into `build-tools/scripts/omnisharp.json.in` and wrote `omnisharp.json` at the repo root for OmniSharp / VS Code C# extension users. The generated file was always `.gitignore`d and **nothing in the repo, build, or CI consumes it** — it was purely a local-dev convenience.
Anyone who actually wants an `omnisharp.json` can keep their own local copy (it remains gitignored). Removing this generation slice is another small step in the slow xaprepare reduction, continuing the pattern from #11568, #11580, #11608, and #11613.
### Audit
Before this change `git grep -in "omnisharp"` returned five hits. After it returns only one — the unrelated MSBuild-context guard in `xaprepare.csproj` that prevents xaprepare's targets from importing under OmniSharp's MSBuild process:
```
build-tools/xaprepare/xaprepare/xaprepare.csproj:52:
<Import Project="xaprepare.targets" Condition=" $(MSBuildToolsPath.IndexOf('omnisharp')) < 0 " />
```
That guard is intentional and is **not** touched by this PR.
### Changes
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`: drop the `Get_Omnisharp_Json (context)` entry from the generated-files list and delete the `Get_Omnisharp_Json` method.
- Delete `build-tools/scripts/omnisharp.json.in`.
The shared properties used by the deleted method (`MicrosoftDotnetSdkInternalPackageVersion`, `DotNetPreviewPath`) are still referenced by `Step_InstallDotNetPreview` and `xaprepare.targets`, so they remain.
### Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` — 0 warnings, 0 errors.
- `git grep -in "omnisharp"` — returns only the unrelated `xaprepare.csproj` guard described above.
- No `Documentation/` references to omnisharp; no `.vscode/` folder in the repo.
- Diff: 3 files, 35 deletions, 0 additions.

[xaprepare] Check in Ndk.projitems, remove generator (#11733)
dc54c1c
Mirrors #11608 (which checked in `Mono.Android.Apis.projitems` the same way). See also #11568, #11580, #11613, #11631, #11657, #11658.
## What
`build-tools/scripts/Ndk.projitems.in` was a template with `@NDK_*@` placeholders that the `Get_Ndk_projitems` generator in xaprepare filled in from constants in `BuildAndroidPlatforms.cs`. Those substitution values only change on rare NDK bumps, so generating the file on every build adds no value.
This PR checks in the resolved file as a static `build-tools/scripts/Ndk.projitems` and removes the generator.
## Changes
- **Add** `build-tools/scripts/Ndk.projitems` — the static, checked-in file. Rather than hardcoding values, it sources them from the existing properties in `Configuration.props` (which is imported before `Ndk.targets`):
- `AndroidNdkVersion` → `$(_XAAndroidNdkRelease)`
- `AndroidNdkPkgRevision` → `$(_XAAndroidNdkPkgRevision)`
- the per-ABI `AndroidNdkApiLevel_*` → `$(AndroidMinimumDotNetApiLevel)`
So there is nothing to keep in sync on an NDK/API bump.
- **`build-tools/scripts/Ndk.targets`** — point `ProjitemsFile` at the new in-tree location (`$(MSBuildThisFileDirectory)Ndk.projitems`) instead of `bin/Build$(Configuration)/Ndk.projitems`.
- **Delete** `build-tools/scripts/Ndk.projitems.in`.
- **`Step_GenerateFiles.cs`** — remove the `Get_Ndk_projitems` method and its dispatch entry.
- **`Configurables.cs`** — update a doc comment reference from `Ndk.projitems.in` → `Ndk.projitems`.
### Simplifications (from review)
- **Collapsed the dead legacy/NET API-level split.** The legacy 32-bit minimum API level used to be lower than the .NET minimum, but they are identical now. Removed the two per-ABI properties that nothing references (`AndroidNdkApiLevel_Arm`, `AndroidNdkApiLevel_X86_Legacy`). The `arm64-v8a`/`x86_64` properties are kept because shipped targets (`Build.Tasks.targets`, `Common.props.in`, `NativeAOT.targets`) still consume them by name.
- **Removed the `ApiLevelNET` item metadata.** `ApiLevelNET` was the .NET (.NET 6+) Android minimum API level vs. the legacy Xamarin.Android/Mono `ApiLevel`; the two are identical now and this repo is .NET-only. Its only consumer was `src/native/common/libunwind/libunwind-xamarin.targets`, which now reads `ApiLevel`. Dropped `ApiLevelNET` from all four `AndroidSupportedTargetJitAbi` items.
The NDK constants in `BuildAndroidPlatforms.cs` are intentionally left untouched — they're still consumed by `Get_XABuildConfig_cs` and the cmake presets generator.
## Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 errors / 0 warnings.
- Evaluated the import chain via a standalone MSBuild harness (importing the real `Configuration.props`); it produces all four `AndroidSupportedTargetJitAbi` items with `ApiLevel`=24 and the expected `AndroidRID` metadata, matching prior generator output (NDK `28c` / pkg `28.2.13676358`).
- Audits clean: `git grep Ndk.projitems.in`, `git grep Ndk_projitems`, `git grep ApiLevelNET`, and the old `bin/Build$(Configuration)/Ndk.projitems` path all return 0 hits.

[xaprepare] Remove unused tool runners and helper classes (#11740)
185bf46
Many xaprepare provisioning steps have been removed over the past year (#11332, #11348, #11399, #11440, #11441, #11636 and follow-up cleanups in #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737). The supporting scaffolding around those steps was left behind. This PR removes the verified-dead pieces in two passes.
## Files removed (first pass — original audit)
| File | Justification |
| --- | --- |
| `Application/TestAssembly.cs` | Orphan test infra; only referenced by `TestAssemblyType.cs`. |
| `Application/TestAssemblyType.cs` | Only referenced by `TestAssembly.cs`. |
| `Application/StepWithDownloadProgress.cs` | No subclasses remain. |
| `Application/NDKTool.cs` | NDK provisioning moved to MSBuild in #11440. Last consumer was the also-dead `Configurables.NDKTools` collection (removed below). |
| `ToolRunners/SnRunner.cs` | Strong-naming tool runner; never instantiated. |
| `ToolRunners/SnRunner.OutputSink.cs` | Partial sibling of `SnRunner`. |
| `ToolRunners/CMakeRunner.cs` | Never instantiated. |
| `ToolRunners/CMakeRunner.OutputSink.cs` | Partial sibling of `CMakeRunner`. |
## Files removed (second pass — repo-wide re-audit)
| File | Justification |
| --- | --- |
| `ToolRunners/MakeRunner.Linux.cs` | Partial of `MakeRunner`; type never instantiated. |
| `ToolRunners/MakeRunner.MacOS.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.OutputSink.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MSBuildRunner.cs` | Never instantiated. |
| `ToolRunners/MSBuildRunner.OutputSink.cs` | Partial sibling of `MSBuildRunner`. |
| `ToolRunners/NinjaRunner.cs` | Never instantiated. |
| `ToolRunners/NinjaRunner.OutputSink.cs` | Partial sibling of `NinjaRunner`. |
| `Application/ScenarioNoStandardEndSteps.cs` | Abstract class with zero subclasses. |
## Cascading cleanup
- `ConfigAndData/Configurables.cs` — removed the dead `NDKTools` `List<NDKTool>` collection (lines 132–145). Rest of the file unchanged.
## Removed from initial deletion list after verification
- `Application/Extensions.DictionaryOfProgramVersionParser.cs` — initial name-only audit flagged it as dead, but its `Add` extension method is consumed via dictionary collection-initializer syntax in `Application/VersionFetchers.cs`. The consumer never references the static class by name, which is why the first audit missed it. The file stays.
- `Scenarios/Scenario_Required.cs` — looks unreferenced by static grep, but `Scenario` subclasses are reflectively discovered via the `[Scenario]` attribute in `Context.cs` (`Utilities.GetTypesWithCustomAttribute<ScenarioAttribute> ()`). Live. The file stays.
## Verification
- `git grep -n -w <TypeName>` for each deleted type now returns 0 real hits (only unrelated `"TestAssembly"` string literals in `tests/Microsoft.Android.Sdk.TrimmableTypeMap.Tests/` remain — those are assembly-name strings, not the C# type).
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 warnings, 0 errors.
## Deferred follow-up
The csproj conditionally excludes `*MacOS*` files from compilation when `HostOS != Darwin`, so static dead-code analysis from a Windows/Linux host can't see whether the macOS-only consumers are themselves live. These candidates need verification on a Mac host (or a build matrix) before deletion:
- `Application/PkgProgram.MacOS.cs`
- `Application/HomebrewProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
- `ConfigAndData/Dependencies/MacOS.cs`

[xaprepare] Move CMake file generation into a dedicated MSBuild proje…
5e9346d
…ct (#11760)
Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.
## What changes
Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:
* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.
Both are now generated by a new project:
* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.
### Why a dedicated project (not just a target in `native.targets`)
The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:
* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).
A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.
### Incremental correctness
`_GenerateCMakeFiles` declares fully-anchored `Inputs`:
* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)
so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)
### Cascading deletions in xaprepare
* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.
`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).
### What stays
The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.
## Verification
On Windows:
* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors
Incremental behaviour verified by walking through MSBuild diagnostic output:
* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.
The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.

[xaprepare] Remove vestigial OS dependency provisioning (#11803)
e89fded
### Context
After #11636 (dotnet provisioning step removed) and #11731 (test-deps scenarios removed), `Context.AutoProvision` is `false` by default everywhere except hand-run dev provisioning, which is no longer in use. The per-OS package lists are populated at `OS.Init()` time but `EnsureDependencies` is effectively a no-op:
- `OS.EnsureDependencies()` returns early when `AutoProvision` is false (the default),
- nothing else in the codebase reads from the `Program` derivatives' install/uninstall paths,
- the `BuildToolsInventory` writer remains driven only from `EssentialTools.MacOS.cs` (homebrew version detection).
The `OS.Init() / InitializeDependencies() / EnsureDependencies()` machinery on `OS.cs` itself is intentionally **left in place** here — that's a larger refactor for a follow-up PR. This PR only strips the now-vestigial package-list data and the program/runner classes that fed it.
### Files deleted (Phase F — macOS, 4 files)
- `Application/HomebrewProgram.MacOS.cs`
- `Application/PkgProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
### Files deleted (Phase G — Linux, 5 files)
- `Application/Program.Linux.cs` (`LinuxProgram` base — orphan after subclasses go)
- `Application/Program.ArchLinux.cs`
- `Application/Program.DebianLinux.cs`
- `Application/Program.FedoraLinux.cs`
- `Application/Program.GentooLinux.cs`
### Files deleted (Phase 3 — orphan)
- `Application/IBuildInventoryItem.cs` (only implementor was `HomebrewProgram`; `BuildToolsInventory` itself stays, populated directly by `EssentialTools.MacOS.cs`).
### Files reduced to empty stubs
`ConfigAndData/Dependencies/`:
- `MacOS.cs` — `InitializeDependencies()` no-op (was Homebrew formula list + git fallback).
- `Linux.Arch.cs` — class kept (referenced by `distroMap`); package list removed.
- `Linux.Fedora.cs` — same.
- `Linux.Gentoo.cs` — same.
- `Linux.DebianCommon.cs` — common Debian/Ubuntu package list removed; `Flavor = "Debian"` kept.
- `Linux.UbuntuCommon.cs` — `libtoolPackages` + `NeedLibtool` virtual + `InitOS` override removed (all dead).
- `Linux.Debian.cs` — all per-version package lists (`packages`, `packagesPre10`, `packagesPreTrixie`, `packagesTrixieAndLater`, `packages10AndNewerBuildBots`) removed; release/codename detection (`EnsureVersionInformation`, `DebianUnstableVersionMap`, `IsDebian10OrNewer`, etc.) preserved as conservative scope.
- `Linux.Ubuntu.cs` — `preCosmicPackages`, `cosmicPackages`, `preDiscoPackages` lists + `NeedLibtool` override removed; `UbuntuRelease` + `EnsureVersionInformation` preserved.
- `Linux.Mint.cs` — `NeedLibtool` override removed (the property is gone from the base).
`ConfigAndData/Dependencies/Windows.cs` was already a no-op stub — no edit.
### Verification
Orphan audit (each `git grep -nw <Type> -- 'build-tools/xaprepare/*'` reports **0 hits**):
- `HomebrewProgram`, `PkgProgram`, `BrewRunner`, `PkgutilRunner`
- `ArchLinuxProgram`, `DebianLinuxProgram`, `FedoraLinuxProgram`, `GentooLinuxProgram`, `LinuxProgram`
- `IBuildInventoryItem`
Build:
```
dotnet build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug
Build succeeded. 0 Warning(s) 0 Error(s)
```
### Out of scope (follow-up)
- Removing the abstract `OS.InitializeDependencies()` declaration and the surrounding `EnsureDependencies()` machinery from `OperatingSystems/OS.cs`.
- `VersionFetchers` / `ProgramVersionParser` / `RegexProgramVersionParser` / `SevenZipVersionParser` / `Extensions.DictionaryOfProgramVersionParser.cs` are kept — `Utilities.GetProgramVersion` still queries them from `Program.cs`, `ToolRunner.cs`, `EssentialTools.MacOS.cs`, and `OperatingSystems/MacOS.cs` (brew detection).
### Precedent
#11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740, #11760

[xaprepare] Move XABuildConfig generation to AndroidBuildConfig.dll (#…
788d363
…11826)
## Summary
Moves `XABuildConfig.cs` generation out of `xaprepare` and into a new strong-named class library at `src/AndroidBuildConfig/AndroidBuildConfig.csproj` that produces `AndroidBuildConfig.dll`.
This continues the incremental removal of `xaprepare`, following the precedent set by `cmake-config.csproj` (#11760) and the recent batch #11568, #11580, #11608, #11613, #11631, #11731, #11732, #11733, #11737, #11740, #11803, #11821, #11825.
It also fixes a long-standing wart: previously `XABuildConfig.cs` was `<Compile Include>`'d into three different assemblies (`Xamarin.Android.Build.Tasks`, `Xamarin.ProjectTools`, and `Xamarin.Android.Build.Tests`), so every test that mentioned `XABuildConfig` produced a `CS0436` "type conflicts with imported type" warning — about **22** of them.
Wrapping the type in its own assembly collapses it to a single definition that every consumer references normally. After this change `Xamarin.Android.Build.Tests` builds with **7** warnings (none for `XABuildConfig`).
## How it works
`src/AndroidBuildConfig/AndroidBuildConfig.csproj`:
- `Microsoft.NET.Sdk` / `netstandard2.0`, strong-named with `product.snk`.
- `ProjectReference`s `Xamarin.Android.Tools.AndroidSdk` (for the `AndroidTargetArch` enum used by the template).
- `<UsingTask>`s `ReplaceFileContents`, `GitCommitHash`, and `GitBranch` from `$(PrepTasksAssembly)`, all with `TaskFactory="TaskHostFactory" Runtime="NET"` per repo convention.
- The `_GenerateXABuildConfig` target runs `BeforeTargets="BeforeCompile;CoreCompile"`, computes every substitution from MSBuild properties already exposed by `Configuration.props` (NDK major/minor/micro via `$(_XAAndroidNdkPkgRevision.Split('.'))`, API levels via `Split`/`Contains`, full commit hash via `GitCommitHash.CommitHash`, branch via `GitBranch.Branch`), and writes the file to `$(IntermediateOutputPath)XABuildConfig.cs`. The `<Compile Include>` lives inside the target so it resolves at execution time, when `IntermediateOutputPath` is final.
- `XABuildConfig` is now `public static class` instead of `internal static class`.
The three consumer csprojs lose their `<Compile Include="…XABuildConfig.cs" />` and now have a normal `<ProjectReference Include="…AndroidBuildConfig.csproj" />` (no `ReferenceOutputAssembly="False"`).
`build-tools/installers/create-installers.targets` ships `AndroidBuildConfig.dll` + `.pdb` alongside `Xamarin.Android.Build.Tasks.dll`.
## xaprepare cleanup
Removed dead code that only existed to feed the old `Get_XABuildConfig_cs` step:
- `Step_GenerateFiles.Get_XABuildConfig_cs` and its `GetMajor` / `GetMinor` locals
- `BuildInfo`: `NDKRevision`, `NDKVersionMajor`, `NDKVersionMinor`, `NDKVersionMicro`, `NDKVersion`, `XACommitHash`, `XABranch`, `GatherGitInfo`, `DetermineXACommitInfo`, `cachedNdkVersion`
- `Context`: the `if (SelectedScenario.NeedsGitBuildInfo) { await BuildInfo.GatherGitInfo … }` block
- `Scenario.NeedsGitBuildInfo` (and the `NeedsGitBuildInfo = true;` setters in `Scenario_Standard` and `Scenario_Required`)
- `BuildAndroidPlatforms.cs` — entire file (only contained constants used by the deleted code)
- `Utilities.ParseAndroidPkgRevision`
- `GitRunner.GetTopCommitHash` and `GitRunner.GetBranchName` (class retained — still used by `BuildInfo.DetermineLastVersionChangeCommit`)
## Files
**Added**
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
**Renamed/moved**
- `build-tools/scripts/XABuildConfig.cs.in` → `src/AndroidBuildConfig/XABuildConfig.cs.in` (`static class` → `public static class`)
**Modified**
- `src/Xamarin.Android.Build.Tasks/Xamarin.Android.Build.Tasks.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.ProjectTools/Xamarin.ProjectTools.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Xamarin.Android.Build.Tests.csproj`
- `build-tools/installers/create-installers.targets`
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`
- `build-tools/xaprepare/xaprepare/Application/BuildInfo.cs`
- `build-tools/xaprepare/xaprepare/Application/Context.cs`
- `build-tools/xaprepare/xaprepare/Application/Scenario.cs`
- `build-tools/xaprepare/xaprepare/Application/Utilities.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Standard.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Required.cs`
- `build-tools/xaprepare/xaprepare/ToolRunners/GitRunner.cs`
- `build-tools/xaprepare/README.md`
**Deleted**
- `build-tools/xaprepare/xaprepare/ConfigAndData/BuildAndroidPlatforms.cs`
## Verification
- `AndroidBuildConfig.csproj`: 0 warnings, 0 errors.
- `Xamarin.Android.Build.Tasks.csproj`: 0 errors, 85 pre-existing unrelated warnings (none for `XABuildConfig`).
- `Xamarin.Android.Build.Tests.csproj`: 0 errors, **7** warnings — down from ~22; all `CS0436 XABuildConfig` conflicts eliminated.
- `xaprepare.csproj`: 0 warnings, 0 errors.
- Generated `XABuildConfig.cs` is semantically identical to the pre-change xaprepare output. The only token difference is the intentional `static class` → `public static class`; everything else (NDK split, API-level major/minor split, supported-ABIs semicolon list, full commit hash, branch name, etc.) matches the previous baseline byte-for-byte.

[xaprepare] Move cgmanifest.json generation from xaprepare to YAML (#…
c7c9458
…11825)
Continues the incremental removal of `xaprepare` by moving the
`cgmanifest.json` generator out of the C# step
`Step_GenerateCGManifest` and into a YAML `pwsh:` step that runs only
on CI.
The file is consumed exclusively by the Azure DevOps Component
Governance Detection task (auto-injected on internal pipelines by
`eng/common/core-templates/job/job.yml`). It is not consumed by any
in-repo build target, so generating it from the C# Prepare step is no
longer necessary.
We cannot drop the file outright: `eng/common` ships CG infrastructure
but it is not yet wired to auto-discover submodules in our pipelines,
so the explicit `cgmanifest.json` is still the source of truth.
Files:
* Added: `build-tools/automation/yaml-templates/generate-cgmanifest.yaml`
* Modified: `build-windows-steps.yaml`, `build-macos-steps.yaml`,
`build-linux-steps.yaml`, `commercial-build.yaml` (call the new
template after the Prepare/`make jenkins` step)
* Modified: `Scenario_Standard.cs` (drop registration)
* Modified: `GitRunner.cs` (remove now-unused `ConfigList` and
`SubmoduleStatus` methods)
* Deleted: `Step_GenerateCGManifest.cs`
Verification: byte-for-byte diff of the YAML-generated
`cgmanifest.json` against the previous C# output on Debug:
Baseline=3144 New=3144
Total byte differences: 0
Precedent PRs in this stream: #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803,
#11821.
### Simplify generate-cgmanifest.yaml using ConvertTo-Json
Replace the hand-rolled StringBuilder JSON emission with PowerShell's
`ConvertTo-Json`. The output is no longer byte-identical to the
previous C# output (2-space indent instead of 4, and slightly
different whitespace), but it is still valid JSON matching the
component-detection-manifest schema. The Azure DevOps Component
Governance Detection task parses the file, so formatting does not
matter.

[xaprepare] Delete redundant Windows JdkInfo.props generator (#11946)
e18dc17
On Windows, xaprepare's Step_GenerateFiles.Windows.cs writes
external/Java.Interop/bin/Build$(Configuration)/JdkInfo.props from
build-tools/xaprepare/xaprepare/Resources/JdkInfo.Windows.props.in.
But this file is immediately overwritten. The PrepareWindows.targets
Prepare flow runs, in order:
1. `dotnet xaprepare -a` — writes JdkInfo.props (this code).
2. `MSBuild Xamarin.Android.BootstrapTasks.sln` — does not read JdkInfo.props.
3. `MSBuild src/workloads/workloads.csproj` — does not read JdkInfo.props.
4. `CallTarget PrepareJavaInterop` → `dotnet build -t:Prepare Java.Interop.sln`
→ external/Java.Interop/build-tools/scripts/Prepare.targets → runs the
`JdkInfo` MSBuild task → overwrites JdkInfo.props with its own generated
content.
Nothing between step 1 and step 4 reads the file, and Java.Interop's Prepare
always regenerates it. Now that external/Java.Interop is in-tree, we can
safely delete the redundant write.
This is the smallest-diff removal:
* Delete Step_GenerateFiles.Windows.cs (the AddOSSpecificSteps partial).
* Delete Resources/JdkInfo.Windows.props.in.
* In Step_GenerateFiles.cs, drop the `partial void AddOSSpecificSteps`
declaration and collapse GetFilesToGenerate so `atBuildStart == false`
returns null. Ctor surface (atBuildStart, onlyRequired) is unchanged so
Scenario_Required.cs is unaffected.
* In Scenario_Standard.cs, remove the AddEndSteps override — the only
thing it did was schedule the now-empty Step_GenerateFiles(atBuildStart:
false).
Preserved (future slices will address these):
* Get_Configuration_OperatingSystem_props (D1).
* OperatingSystems/*.cs and Context.OS.* surface.
* PrepareWindows.targets, DotNet.targets, Java.Interop's Prepare.targets.
Verification:
* dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug
→ Build succeeded. 0 Warning(s). 0 Error(s).
* build.cmd -t:Prepare -c Debug (Windows, cold tree) → succeeds; the file
external/Java.Interop/bin/BuildDebug/JdkInfo.props exists.
* Compare-Object of the resulting JdkInfo.props before vs after this
change → byte-identical (1493 bytes, SHA256
DE59A8061B7657831788FFED7BC1DEECA442E9181605083A4553DE7AC8C003A1),
confirming Java.Interop's overwrite is what always ends up on disk.
* Grep audit under build-tools/xaprepare/: no remaining references to
Step_GenerateFiles.Windows, JdkInfo.Windows.props.in, or
AddOSSpecificSteps.

[xaprepare] Delete Configuration.OperatingSystem.props generator and …
be5272c
…xaprepare project (#11959)
Follow-up to #11956, which moved the JDK half of `Configuration.OperatingSystem.props` to Java.Interop's `JdkInfo.props`. The remaining NDK / OS-info half has zero real consumers, so this PR:
1. Deletes the last generator template (`Configuration.OperatingSystem.props.in`).
2. Cascades through `Step_GenerateFiles`, both `Scenario_*` classes (which now had zero steps), and every supporting `OperatingSystems/`, `Context.*OS.cs`, `EssentialTools.*`, `ToolRunners/*`, `Configurables.*`, `Application/*`, and `Main.cs` file that only existed to feed the scenarios.
3. Deletes the whole `build-tools/xaprepare/` project.
4. Patches every integration point (`Makefile`, `PrepareWindows.targets`, `BuildEverything.mk`, CI YAML, docs) so `build.cmd -t:Prepare` and `make prepare` still work end-to-end.
## `Configuration.OperatingSystem.props.in` placeholder audit
| Placeholder | Consumers outside the `.in` file | Action |
| --- | --- | --- |
| `HostOsName` | none | drop |
| `HostOsFlavor` | none | drop |
| `HostOsRelease` | none | drop |
| `HostBits` | none (`ArchiveBase.HostBits` in `src/Xamarin.Installer.AndroidSDK/` is an unrelated C# property) | drop |
| `NdkLlvmTag` | none (the NDK toolchain OS tag is resolved elsewhere via `_NdkToolchainOSTag` in `androidsdk.targets`) | drop |
| `HostCpuCount` | only `Configuration.props:72` via `$(MakeConcurrency)` | drop |
## `$(MakeConcurrency)` audit
The only definition was `Configuration.props:72`. A repo-wide grep of `.targets`, `.props`, `.projitems`, `Makefile`, and `.mk` files found zero consumers of the MSBuild property. The `MakeConcurrency` hits under `build-tools/xaprepare/` were an unrelated C# `Context.MakeConcurrency` property.
**Result:** dropped the `MakeConcurrency` MSBuild property entirely (no `$([System.Environment]::ProcessorCount)` replacement needed) and removed the `$(MakeConcurrency)` bullet in `Documentation/building/configuration.md`.
## xaprepare integration audit (grep-confirmed, patched here)
| Location | Change |
| --- | --- |
| `build-tools/xaprepare/` (entire tree) | **deleted** — 86 tracked files |
| `Configuration.props` | dropped `<Import>` of the generated OS props, dropped `MakeConcurrency`, tidied the "between xaprepare and package creation tools" comment |
| `.gitignore` | dropped `Configuration.OperatingSystem.props` |
| `build-tools/scripts/PrepareWindows.targets` | removed `_XAPrepareExe`, `_XAPrepareStandardArgs`, `_BuildXAPrepare` target, and the `Exec dotnet $(_XAPrepareExe)` line. Repointed `Prepare` at `_InstallDotNet`. Kept the space-in-path guard, BootstrapTasks / workloads MSBuilds, and `PrepareJavaInterop` |
| `Makefile` | dropped `PREPARE_PROJECT`, `PREPARE_NET_FX`, `PREPARE_ARGS`, `PREPARE_MSBUILD_FLAGS`, `PREPARE_SCENARIO`, `PREPARE_CI_PR`, `PREPARE_CI`, `_PREPARE_CI_MODE_*`, `_PREPARE_ARGS`, and all their conditionals. Dropped the `dotnet run --project xaprepare.csproj` line from `prepare`. Deleted the `prepare-help` target |
| `build-tools/scripts/BuildEverything.mk` | `jenkins` no longer branches on `PREPARE_CI_PR`/`PREPARE_CI`; just `$(MAKE) prepare && $(MAKE) leeroy` |
| `.github/workflows/copilot-setup-steps.yml` | dropped now-unused `PREPARE_CI=1` |
| `build-tools/automation/azure-pipelines-apidocs.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-linux-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-macos-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/commercial-build.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/copy-extra-result-files.yaml` | dropped `**/Configuration.OperatingSystem.props` glob and the stale `Step_CopyExtraResultFilesForCI` xaprepare-step comment |
| `build-tools/automation/yaml-templates/generate-cgmanifest.yaml` | dropped the stale `Step_GenerateCGManifest` xaprepare-step comment |
| `build-tools/automation/yaml-templates/setup-jdk-variables.yaml` | renamed `$xaPrepareJdkPath` → `$xaJdkPath` for hygiene |
| `Documentation/workflow/HowToAddNewApiLevel.md` | rewrote the "Add New Platform" section to point at `<_PlatformPackage>` entries in `src/androidsdk/androidsdk.targets` instead of `AndroidToolchain.cs`; updated the `--android-sdk-platforms=all` recipe to `dotnet-local build src/androidsdk/androidsdk.csproj -p:AndroidSdkPlatforms=all` |
| `Documentation/building/unix/dependencies.md` | JDK-version link now points at `$(MicrosoftOpenJDKVersion)` in `/Configuration.props` instead of the deleted `Configurables.cs` |
| `Documentation/building/configuration.md` | removed the `$(MakeConcurrency)` bullet |
**Historical breadcrumb comments left as-is** (still accurate and useful for git-archaeology):
- `.github/skills/update-tpn/SKILL.md`
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
- `src/androidsdk/androidsdk.targets`
- `src/native/cmake-config/cmake-config.csproj`
- `src/workloads/workloads.csproj`
## Verification
- `build.cmd Prepare` — succeeded end-to-end on Windows (0 warnings, 0 errors). The trimmed `Prepare` target ran through `_InstallDotNet`, the space-in-path guard, `Xamarin.Android.BootstrapTasks.sln`, `src/workloads/workloads.csproj`, and `PrepareJavaInterop`.
- `dotnet build src\Xamarin.Android.Build.Tasks\Xamarin.Android.Build.Tasks.csproj -c Debug` — 0 errors (93 pre-existing warnings from `src/Mono.Android/` and generated MCW, unrelated to this change).
- Repo-wide grep for `HostOsName`, `HostOsFlavor`, `HostOsRelease`, `HostCpuCount`, `NdkLlvmTag`, and the MSBuild `MakeConcurrency` property — clean.
- Repo-wide grep for `xaprepare` — clean apart from the five intentional historical breadcrumb comments listed above.

Why
bin/configuration.mk exists only to persist CONFIGURATION=<value> between Unix make invocations. Removing it lets us delete the only meaningful contents of Step_GenerateFiles.Unix.cs, continuing the slow removal of xaprepare (see precedent: #11568, #11529).
What
  • Drop -include bin/configuration.mk from the top of Makefile. The CONFIGURATION ?= Debug fallback at the top of the file is unchanged.
  • Delete build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs entirely (it contained GeneratedConfigurationFile and a one-line AddUnixPostBuildSteps partial that registered it).
The partial void AddUnixPostBuildSteps (Context context, List<GeneratedFile> steps); declaration in Step_GenerateFiles.cs is intentionally left in place — partial methods without an implementation are legal in C#, and the call site becomes a zero-cost no-op. Step_GenerateFiles.Windows.cs implements a different partial (AddOSSpecificSteps) and is unaffected.
Why this is safe
CallerPre-change behaviorPost-change behavior
All CI YAML (build-linux-steps.yaml, build-macos-steps.yaml, commercial-build.yaml, azure-pipelines-apidocs.yaml)Passes CONFIGURATION=$(XA.Build.Configuration) on every make callSame — explicit value still wins
build.sh (make prepare && make jenkins && make pack-dotnet)First make prepare runs against an empty bin/, so the -include no-ops and ?= Debug takes effectIdentical — ?= Debug still takes effect
Fresh local checkout, bare make all?= Debug (no bin/configuration.mk yet)Same
Local dev who runs make prepare CONFIGURATION=Release then bare make allPersisted Release via bin/configuration.mkNow defaults back to Debug — must pass CONFIGURATION=Release on every invocation
That last case is the only behavior change. It was never documented as a contract anywhere in Documentation/ or README.md, and developers building Release locally should be passing the flag explicitly anyway.
Verification
  • git grep "configuration\.mk" and git grep "GeneratedConfigurationFile": zero matches after this change.
  • dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj: 0 warnings, 0 errors.
  • Rubber-duck review: no remaining Path.Combine(..., "configuration.mk") references, no Makefile target depends on bin/configuration.mk as a prerequisite, and the leftover partial-method declaration is benign.

[build] Remove unused bin/configuration.mk
1ad2d35
`bin/configuration.mk` existed only to persist `CONFIGURATION=<value>`
between Unix `make` invocations. CI passes `CONFIGURATION=...` explicitly
on every `make` call, and `build.sh` never sets it (so a fresh checkout
always hit the `CONFIGURATION ?= Debug` default anyway). Dropping the
include lets us delete the only meaningful contents of
`Step_GenerateFiles.Unix.cs`, continuing the slow removal of xaprepare.
- Drop `-include bin/configuration.mk` from the top of `Makefile`. The
`CONFIGURATION ?= Debug` fallback is unchanged.
- Delete `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.cs`
entirely. The `partial void AddUnixPostBuildSteps (...)` declaration in
`Step_GenerateFiles.cs` is left as a no-op (legal C#); the call site
becomes a zero-cost no-op. `Step_GenerateFiles.Windows.cs` implements a
different partial (`AddOSSpecificSteps`) and is unaffected.

FileDescription
MakefileStops including bin/configuration.mk, leaving CONFIGURATION ?= Debug as the sole default mechanism.
build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.Unix.csRemoves the generator that created bin/configuration.mk and the Unix partial-step registration.

Drop now-dead AddUnixPostBuildSteps partial
5a770f4
After deleting `Step_GenerateFiles.Unix.cs`, the `partial void
AddUnixPostBuildSteps (...)` declaration and its call site in
`Step_GenerateFiles.cs` were no-ops. Remove them so the file no longer
references a vestige of the `bin/configuration.mk` generator.

[xaprepare] Check inMono.Android.Apis.projitems, remove generator (#…
63951b8
…11608)
`Mono.Android.Apis.projitems` was previously generated at prepare time by
`GeneratedMonoAndroidProjitemsFile` (in xaprepare) from the
`BuildAndroidPlatforms.AllPlatforms` list. Both had exactly one consumer
(each other), so check in the projitems as a source file and drop the
generator plumbing.
Changes:
* Add `src/Mono.Android/Mono.Android.Apis.projitems` — content matches
the generator's output byte-for-byte; only the header comment now
points at `Documentation/workflow/HowToAddNewApiLevel.md` instead of
declaring "GENERATED FILE".
* Repoint the 4 importers (`Mono.Android.targets` x2,
`create-installers.targets`, `create-android-api.csproj`,
`Xamarin.Android.Build.Tasks.targets`) at the new path and drop the
`Condition="Exists(...)"` guards — the file is always present now.
* Delete `GeneratedMonoAndroidProjitemsFile.cs` and `AndroidPlatform.cs`
(whole files — `AndroidPlatform` class and `AndroidPlatformExtensions`
both become unused).
* Drop the `new GeneratedMonoAndroidProjitemsFile()` registration in
`Step_GenerateFiles.cs`.
* Remove `BuildAndroidPlatforms.AllPlatforms` and the now-unused
`using System.Collections.Generic;`. Keep the NDK constants
(`AndroidNdkVersion`, `AndroidNdkPkgRevision`, `NdkMinimumAPI`,
`NdkMinimumAPILegacy32`) — they still have consumers.
* Update `Documentation/workflow/HowToAddNewApiLevel.md` with the
XML-based instructions for adding a new API level.
* Narrow the `build-tools/xaprepare/README.md` blurb for
`BuildAndroidPlatforms.cs` to NDK metadata.
* Fix stale doc comment in `GenerateSupportedPlatforms.cs` pointing
at the old generated path.
Continues the xaprepare cleanup started in PRs #11568 and #11580.
### [docs] Fix Stable=True/False contradiction in HowToAddNewApiLevel
The added prose said Stable should be False for preview API levels, but the
example (CANARY) sets <Stable>True</Stable>, and every entry in
Mono.Android.Apis.projitems is True. Rewrite the prose to match the data and
briefly explain what setting Stable=False would actually do (excludes entry
from default stable framework selection).

* [Xamarin.AndroidTools] Remove dead VS Mac / legacy code (#11607)
Context: after the `android-platform-support` repo was inlined here
(see c22cdcf), `src/Xamarin.AndroidTools/` carries a large amount of
code that was only used by old VS Mac / installer / debugger-host
workflows that are no longer part of the .NET for Android product. None
of these types have callers anywhere in this repo, in
`external/xamarin-android-tools/`, or in `external/Java.Interop/`.
Removed (13 files):
* `PublicationUtilities/PublishAndroidApplication.cs`
* `PublicationUtilities/PackageSigningTasks.cs`
* `PublicationUtilities/KeyManagement.cs`
* `PublicationUtilities/KeystoreEntry.cs`
* `Sessions/AndroidDeploySession.cs`
* `Sessions/AndroidConnectCommandSession.cs`
* `Sessions/AndroidCommandSession.cs`
* `Sessions/AndroidDeploymentException.cs`
* `Devices/AndroidPackageList.cs`
* `Devices/AndroidPackageListExtensions.cs`
* `Debugging/MonoDroidProcessMonitor.cs`
* `PlatformPackage.cs`
* `IProgressNotifier.cs`
* `AndroidSigningOptions.cs`
Moved (still needed by `ProcessUtils.cs`):
* `PublicationUtilities/AndroidSdkToolException.cs` ->
`AndroidSdkToolException.cs` (namespace unchanged)
Pruned from `Devices/AndroidDeviceExtensions.cs` (the methods only
referenced the just-deleted types and had no in-tree callers):
* `StartActivityWithCommandSession` (used `AndroidCommandSession`)
* `GetDeploySession`, `GetPackagesAsync`, `GetPackages` (used
`AndroidDeploySession` / `IProgressNotifier`)
* `InstallSharedRuntime*` and `InstallSharedPlatform*` overloads
that took `IProgressNotifier`
* `GetPackageRemotePath`/`GetPackageRemotePathAsync` (used
`AndroidDeploymentException`)
* `GetFastDevRemotePath`/`GetFastDevRemotePathAsync` and the inner
`FastDevRemotePathInfo` class (only consumer was
`GetPackageRemotePathAsync`)
Kept methods in `AndroidDeviceExtensions.cs` are the ones still used
by `Xamarin.Android.Build.Debugging.Tasks` (`EnsureProperties`,
`KillProcessAndWaitForExit`, `PushAndInstallPackageAsync`) and by
`DebuggingExtensions` (`SetFastDevPropertyFile`, `GetProcessIDAsync`,
`SetDebugPropertiesAsync`).
Also cleaned up:
* `Properties/Resources.resx` (English source): removed seven
`CreateKeyError_*` strings that only `KeyManagement.cs` used.
* `Properties/Resources.Designer.cs`: removed the seven matching
properties.
* `MonoDroidSdk.cs`: two `[Obsolete]` messages referenced the
now-deleted `PlatformPackage`; changed to `"Do not use."`.
Non-English `Resources.*.resx` and `Localize/loc/**/*.lcl` are left
alone per repo policy (auto-regenerated by OneLocBuild).
Build verified locally:
* `src/Xamarin.AndroidTools/Xamarin.AndroidTools.csproj`
* `src/Mono.AndroidTools/Mono.AndroidTools.csproj`
* `src/Xamarin.Android.Build.Debugging.Tasks/Xamarin.Android.Build.Debugging.Tasks.csproj`
* `src/Xamarin.Installer.AndroidSDK/Xamarin.Installer.AndroidSDK.csproj`
Net change: -4225 / +2 lines across 19 files.

* [NUnitLite] Add OneTimeSetUp/OneTimeTearDown attribute shims
NUnit 3.x renamed [TestFixtureSetUp]/[TestFixtureTearDown] to [OneTimeSetUp]/[OneTimeTearDown]. dotnet/java-interop#1437 migrated the Java.Interop test suite to the new names.
The bundled Xamarin.Android.NUnitLite (src-ThirdParty/NUnitLite/) only defines the legacy names. Add no-op subclasses for the new names so test source using [OneTimeSetUp]/[OneTimeTearDown] still compiles against bundled NUnitLite once the Java.Interop submodule is bumped past dotnet/java-interop#1437.
These shims become unnecessary once dotnet/android moves off bundled NUnitLite to stock NUnit (tracked in PR #11224).

@jonathanpeppers
[build] Remove Step_PrepareProps; fold values into eng/Versions.props (…
ee0392c
…#11613)
Continues the slow `xaprepare` removal. Recent precedent: #11568 (CopyExtraResultFilesForCI → YAML), #11580 (configuration.mk removal), #11529 (android-platform-support consolidation, which also dropped `Step_PrepareExternalGitDependencies`).
## What
`Step_PrepareProps` generated `external/Java.Interop/Configuration.Override.props` (inside the submodule) by substituting two placeholders into `build-tools/scripts/Configuration.Java.Interop.Override.in.props`. The substituted properties (`_XamarinAndroidCecilVersion`, `UtilityOutputFullPathCoreApps`, `XamarinAndroidToolsDirectory`) are now supplied directly via the checked-in static file `external/Java.Interop.override.props`, which Java.Interop's own `Directory.Build.props` already auto-imports via the parent-dir convention added in dotnet/java-interop#872.
The shared version values (`MonoCecilVersion`, `AndroidPackVersion`, `AndroidPackVersionSuffix`) move into `eng/Versions.props`. `Directory.Build.props` and `external/Java.Interop.override.props` both `<Import>` it. No duplicate-import sentinel is needed because every code path that imports `Configuration.props` has already loaded `Directory.Build.props` (either via MSBuild auto-load or via the explicit `<Import>` in `external/xamarin-android-tools.override.props`).
`MicrosoftAndroidSdkPackName` stays in `Configuration.props` (it is OS-conditioned, not version-shaped, so it doesn't belong in `Versions.props`). The same 3-line OS-conditioned block is mirrored privately in `external/Java.Interop.override.props` as `_MicrosoftAndroidSdkPackName`, used only to compute `UtilityOutputFullPathCoreApps` for the Java.Interop build.
Also dropped:
- `Configurables.Paths.InstallMSBuildDir` and its backing field — the only consumer was `Step_PrepareProps`.
- The dead `UtilityOutputFullPath` line in the old template — Java.Interop's `TargetFrameworkDependentValues.props` unconditionally routes it to `$(UtilityOutputFullPathCoreApps)` anyway, so it was a no-op.
Updated `build-tools/scripts/XAVersionInfo.targets` (the `GitBlame` for `<AndroidPackVersion>` now points at `eng/Versions.props`) and `Documentation/guides/HowToBranch.md` to reflect the moves.
## Why not just `<Import>` `Directory.Build.props` from the Java.Interop override?
That was the original idea. I prototyped it: importing dotnet/android's full props chain from `external/Java.Interop.override.props` flips `DotNetTargetFrameworkVersion` from `10.0` to `11.0` inside Java.Interop, and `dotnet restore Java.Interop.csproj` then fails with:
```
NETSDK1045: The current .NET SDK does not support targeting .NET 11.0
```
`xamarin-android-tools.override.props` gets away with the same trick only because its sole csproj sets `AndroidToolsDisableMultiTargeting=true`, which makes the TFM-clobber harmless. Java.Interop has no equivalent escape hatch.
`eng/Versions.props` is collision-free with Java.Interop (verified against the submodule sources — none of the existing entries collide), has no `<Import>` of its own, and is the safe minimal shared file.
## Verification
On Windows:
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj` — 0 warnings, 0 errors.
- From `src/Xamarin.Android.Build.Tasks/`: `dotnet msbuild --getProperty:MonoCecilVersion,AndroidPackVersion,AndroidPackVersionSuffix,MicrosoftAndroidSdkPackName,MicrosoftAndroidSdkOutDir` — values unchanged from baseline.
- From `external/Java.Interop/src/Java.Interop/`:
- `dotnet msbuild --getProperty:DotNetTargetFramework,_XamarinAndroidCecilVersion,UtilityOutputFullPathCoreApps` returns `net10.0`, `0.11.5`, the expected packs/tools path.
- `dotnet restore Java.Interop.csproj` succeeds (no `NETSDK1045`).

@jonathanpeppers
[build] Remove omnisharp.json generation from xaprepare (#11631)
58ccc1f
### Context
`Get_Omnisharp_Json` in `Step_GenerateFiles` substituted two placeholders into `build-tools/scripts/omnisharp.json.in` and wrote `omnisharp.json` at the repo root for OmniSharp / VS Code C# extension users. The generated file was always `.gitignore`d and **nothing in the repo, build, or CI consumes it** — it was purely a local-dev convenience.
Anyone who actually wants an `omnisharp.json` can keep their own local copy (it remains gitignored). Removing this generation slice is another small step in the slow xaprepare reduction, continuing the pattern from #11568, #11580, #11608, and #11613.
### Audit
Before this change `git grep -in "omnisharp"` returned five hits. After it returns only one — the unrelated MSBuild-context guard in `xaprepare.csproj` that prevents xaprepare's targets from importing under OmniSharp's MSBuild process:
```
build-tools/xaprepare/xaprepare/xaprepare.csproj:52:
<Import Project="xaprepare.targets" Condition=" $(MSBuildToolsPath.IndexOf('omnisharp')) < 0 " />
```
That guard is intentional and is **not** touched by this PR.
### Changes
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`: drop the `Get_Omnisharp_Json (context)` entry from the generated-files list and delete the `Get_Omnisharp_Json` method.
- Delete `build-tools/scripts/omnisharp.json.in`.
The shared properties used by the deleted method (`MicrosoftDotnetSdkInternalPackageVersion`, `DotNetPreviewPath`) are still referenced by `Step_InstallDotNetPreview` and `xaprepare.targets`, so they remain.
### Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` — 0 warnings, 0 errors.
- `git grep -in "omnisharp"` — returns only the unrelated `xaprepare.csproj` guard described above.
- No `Documentation/` references to omnisharp; no `.vscode/` folder in the repo.
- Diff: 3 files, 35 deletions, 0 additions.

[xaprepare] Check in Ndk.projitems, remove generator (#11733)
dc54c1c
Mirrors #11608 (which checked in `Mono.Android.Apis.projitems` the same way). See also #11568, #11580, #11613, #11631, #11657, #11658.
## What
`build-tools/scripts/Ndk.projitems.in` was a template with `@NDK_*@` placeholders that the `Get_Ndk_projitems` generator in xaprepare filled in from constants in `BuildAndroidPlatforms.cs`. Those substitution values only change on rare NDK bumps, so generating the file on every build adds no value.
This PR checks in the resolved file as a static `build-tools/scripts/Ndk.projitems` and removes the generator.
## Changes
- **Add** `build-tools/scripts/Ndk.projitems` — the static, checked-in file. Rather than hardcoding values, it sources them from the existing properties in `Configuration.props` (which is imported before `Ndk.targets`):
- `AndroidNdkVersion` → `$(_XAAndroidNdkRelease)`
- `AndroidNdkPkgRevision` → `$(_XAAndroidNdkPkgRevision)`
- the per-ABI `AndroidNdkApiLevel_*` → `$(AndroidMinimumDotNetApiLevel)`
So there is nothing to keep in sync on an NDK/API bump.
- **`build-tools/scripts/Ndk.targets`** — point `ProjitemsFile` at the new in-tree location (`$(MSBuildThisFileDirectory)Ndk.projitems`) instead of `bin/Build$(Configuration)/Ndk.projitems`.
- **Delete** `build-tools/scripts/Ndk.projitems.in`.
- **`Step_GenerateFiles.cs`** — remove the `Get_Ndk_projitems` method and its dispatch entry.
- **`Configurables.cs`** — update a doc comment reference from `Ndk.projitems.in` → `Ndk.projitems`.
### Simplifications (from review)
- **Collapsed the dead legacy/NET API-level split.** The legacy 32-bit minimum API level used to be lower than the .NET minimum, but they are identical now. Removed the two per-ABI properties that nothing references (`AndroidNdkApiLevel_Arm`, `AndroidNdkApiLevel_X86_Legacy`). The `arm64-v8a`/`x86_64` properties are kept because shipped targets (`Build.Tasks.targets`, `Common.props.in`, `NativeAOT.targets`) still consume them by name.
- **Removed the `ApiLevelNET` item metadata.** `ApiLevelNET` was the .NET (.NET 6+) Android minimum API level vs. the legacy Xamarin.Android/Mono `ApiLevel`; the two are identical now and this repo is .NET-only. Its only consumer was `src/native/common/libunwind/libunwind-xamarin.targets`, which now reads `ApiLevel`. Dropped `ApiLevelNET` from all four `AndroidSupportedTargetJitAbi` items.
The NDK constants in `BuildAndroidPlatforms.cs` are intentionally left untouched — they're still consumed by `Get_XABuildConfig_cs` and the cmake presets generator.
## Verification
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 errors / 0 warnings.
- Evaluated the import chain via a standalone MSBuild harness (importing the real `Configuration.props`); it produces all four `AndroidSupportedTargetJitAbi` items with `ApiLevel`=24 and the expected `AndroidRID` metadata, matching prior generator output (NDK `28c` / pkg `28.2.13676358`).
- Audits clean: `git grep Ndk.projitems.in`, `git grep Ndk_projitems`, `git grep ApiLevelNET`, and the old `bin/Build$(Configuration)/Ndk.projitems` path all return 0 hits.

[xaprepare] Remove unused tool runners and helper classes (#11740)
185bf46
Many xaprepare provisioning steps have been removed over the past year (#11332, #11348, #11399, #11440, #11441, #11636 and follow-up cleanups in #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737). The supporting scaffolding around those steps was left behind. This PR removes the verified-dead pieces in two passes.
## Files removed (first pass — original audit)
| File | Justification |
| --- | --- |
| `Application/TestAssembly.cs` | Orphan test infra; only referenced by `TestAssemblyType.cs`. |
| `Application/TestAssemblyType.cs` | Only referenced by `TestAssembly.cs`. |
| `Application/StepWithDownloadProgress.cs` | No subclasses remain. |
| `Application/NDKTool.cs` | NDK provisioning moved to MSBuild in #11440. Last consumer was the also-dead `Configurables.NDKTools` collection (removed below). |
| `ToolRunners/SnRunner.cs` | Strong-naming tool runner; never instantiated. |
| `ToolRunners/SnRunner.OutputSink.cs` | Partial sibling of `SnRunner`. |
| `ToolRunners/CMakeRunner.cs` | Never instantiated. |
| `ToolRunners/CMakeRunner.OutputSink.cs` | Partial sibling of `CMakeRunner`. |
## Files removed (second pass — repo-wide re-audit)
| File | Justification |
| --- | --- |
| `ToolRunners/MakeRunner.Linux.cs` | Partial of `MakeRunner`; type never instantiated. |
| `ToolRunners/MakeRunner.MacOS.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.OutputSink.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MakeRunner.Unix.cs` | Partial of `MakeRunner`. |
| `ToolRunners/MSBuildRunner.cs` | Never instantiated. |
| `ToolRunners/MSBuildRunner.OutputSink.cs` | Partial sibling of `MSBuildRunner`. |
| `ToolRunners/NinjaRunner.cs` | Never instantiated. |
| `ToolRunners/NinjaRunner.OutputSink.cs` | Partial sibling of `NinjaRunner`. |
| `Application/ScenarioNoStandardEndSteps.cs` | Abstract class with zero subclasses. |
## Cascading cleanup
- `ConfigAndData/Configurables.cs` — removed the dead `NDKTools` `List<NDKTool>` collection (lines 132–145). Rest of the file unchanged.
## Removed from initial deletion list after verification
- `Application/Extensions.DictionaryOfProgramVersionParser.cs` — initial name-only audit flagged it as dead, but its `Add` extension method is consumed via dictionary collection-initializer syntax in `Application/VersionFetchers.cs`. The consumer never references the static class by name, which is why the first audit missed it. The file stays.
- `Scenarios/Scenario_Required.cs` — looks unreferenced by static grep, but `Scenario` subclasses are reflectively discovered via the `[Scenario]` attribute in `Context.cs` (`Utilities.GetTypesWithCustomAttribute<ScenarioAttribute> ()`). Live. The file stays.
## Verification
- `git grep -n -w <TypeName>` for each deleted type now returns 0 real hits (only unrelated `"TestAssembly"` string literals in `tests/Microsoft.Android.Sdk.TrimmableTypeMap.Tests/` remain — those are assembly-name strings, not the C# type).
- `dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug` → 0 warnings, 0 errors.
## Deferred follow-up
The csproj conditionally excludes `*MacOS*` files from compilation when `HostOS != Darwin`, so static dead-code analysis from a Windows/Linux host can't see whether the macOS-only consumers are themselves live. These candidates need verification on a Mac host (or a build matrix) before deletion:
- `Application/PkgProgram.MacOS.cs`
- `Application/HomebrewProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
- `ConfigAndData/Dependencies/MacOS.cs`

[xaprepare] Move CMake file generation into a dedicated MSBuild proje…
5e9346d
…ct (#11760)
Continues the incremental dismantling of `xaprepare` (see #11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740). Two more generator methods come out, and the work they did moves into a small dedicated MSBuild project.
## What changes
Two xaprepare generators in `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs` are deleted:
* `Get_Cmake_XA_Build_Configuration` — produced `bin/Build$(Configuration)/xa_build_configuration.cmake`, included by `src/native/CMakeLists.txt`.
* `Get_Cmake_Presets` (and its `GetCmakePresetsCommon` helper) — produced `src/native/CMakePresets.json`, consumed by the `cmake` preset invocations in `src/native/native.targets`.
Both are now generated by a new project:
* **`src/native/cmake-config/cmake-config.csproj`** (`Microsoft.Build.NoTargets`) hosts `_GenerateCMakeFiles`, which uses the existing `ReplaceFileContents` MSBuild task to substitute the placeholders in `build-tools/scripts/xa_build_configuration.cmake.in` and `src/native/CMakePresets.json.in`.
* `native-mono.csproj`, `native-clr.csproj`, and `native-nativeaot.csproj` each `<ProjectReference>` this project.
### Why a dedicated project (not just a target in `native.targets`)
The three native csproj share two output files (`bin/Build$(Configuration)/xa_build_configuration.cmake` and `src/native/CMakePresets.json`). Hosting the generator in `native.targets` would either:
* Race on the shared outputs under parallel msbuild (`/m`), or
* Require a `'$(MSBuildProjectName)' == 'native-mono'` gate -- which breaks isolated `dotnet build native-clr.csproj` on a clean tree (the gitignored output files would never get generated).
A dedicated project with three incoming `<ProjectReference>`s solves both: single producer, and project-reference ordering guarantees the outputs exist before any consumer's `cmake` preset call -- including for isolated single-csproj builds.
### Incremental correctness
`_GenerateCMakeFiles` declares fully-anchored `Inputs`:
* `build-tools/scripts/xa_build_configuration.cmake.in`
* `src/native/CMakePresets.json.in`
* `Configuration.props` (`AndroidNdkDirectory`, `NinjaPath`, `MicrosoftAndroidSdkOutDir`, `XAPackagesDir`, `AndroidMinimumDotNetApiLevel`)
* `Directory.Build.props` (`TestOutputDirectory`)
* `eng/Versions.props` (`MicrosoftNETCoreAppRefPackageVersion`)
so editing any of those re-runs the target; a no-change rebuild skips it. (Note: `$(MSBuildAllProjects)` is intentionally **not** used -- it does not include imported `.props` files for SDK-style projects since MSBuild 16.0; verified empirically.)
### Cascading deletions in xaprepare
* `Configurables.NativeSourcesDir` (was used only by `Get_Cmake_Presets`).
* All eight `Configurables.Paths.NetcoreAppRuntimeAndroid*` / `CoreClrAppRuntimeAndroid*` properties (+ backing fields + the `GetNetcoreAppRuntimePath` / `GetCoreClrAppRuntimePath` helpers) -- the new MSBuild target reads `$(XAPackagesDir)` / `$(MicrosoftNETCoreAppRefPackageVersion)` directly.
* The `Get_Cmake_*` entries in `Step_GenerateFiles.GetFilesToGenerate`.
`BuildAndroidPlatforms.NdkMinimumAPI` / `NdkMinimumAPILegacy32` are kept -- still used by `Get_XABuildConfig_cs` (a separate generator for a future PR).
### What stays
The `.in` template files are unchanged and still tracked in git -- the new MSBuild target reads them. The other generators in `Step_GenerateFiles.cs` (`Get_SourceLink_Json`, `Get_Configuration_OperatingSystem_props`, `Get_XABuildConfig_cs`, `AddOSSpecificSteps`) are out of scope and untouched.
## Verification
On Windows:
* `build.cmd Prepare -c Debug`
* `dotnet-local.cmd build src\native\native-mono.csproj -c Debug` -> 0 errors, generates both files
* `dotnet-local.cmd build src\native\native-clr.csproj -c Debug` -> 0 errors (incl. clean-tree isolated build)
* `dotnet-local.cmd build src\native\native-nativeaot.csproj -c Debug` -> 0 errors
* `dotnet-local.cmd build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug` -> 0 errors
Incremental behaviour verified by walking through MSBuild diagnostic output:
* No-change rebuild: `Skipping target "_GenerateCMakeFiles" because all output files are up-to-date`.
* `touch eng/Versions.props` + rebuild: `Building target "_GenerateCMakeFiles" completely`, outputs re-written.
The generated `CMakePresets.json` and `xa_build_configuration.cmake` were diffed against the xaprepare baselines captured before the deletion; only the path separator normalisation (forward slashes throughout) differs, which both CMake and JSON accept on every platform.

[xaprepare] Remove vestigial OS dependency provisioning (#11803)
e89fded
### Context
After #11636 (dotnet provisioning step removed) and #11731 (test-deps scenarios removed), `Context.AutoProvision` is `false` by default everywhere except hand-run dev provisioning, which is no longer in use. The per-OS package lists are populated at `OS.Init()` time but `EnsureDependencies` is effectively a no-op:
- `OS.EnsureDependencies()` returns early when `AutoProvision` is false (the default),
- nothing else in the codebase reads from the `Program` derivatives' install/uninstall paths,
- the `BuildToolsInventory` writer remains driven only from `EssentialTools.MacOS.cs` (homebrew version detection).
The `OS.Init() / InitializeDependencies() / EnsureDependencies()` machinery on `OS.cs` itself is intentionally **left in place** here — that's a larger refactor for a follow-up PR. This PR only strips the now-vestigial package-list data and the program/runner classes that fed it.
### Files deleted (Phase F — macOS, 4 files)
- `Application/HomebrewProgram.MacOS.cs`
- `Application/PkgProgram.MacOS.cs`
- `ToolRunners/BrewRunner.MacOS.cs`
- `ToolRunners/PkgutilRunner.MacOS.cs`
### Files deleted (Phase G — Linux, 5 files)
- `Application/Program.Linux.cs` (`LinuxProgram` base — orphan after subclasses go)
- `Application/Program.ArchLinux.cs`
- `Application/Program.DebianLinux.cs`
- `Application/Program.FedoraLinux.cs`
- `Application/Program.GentooLinux.cs`
### Files deleted (Phase 3 — orphan)
- `Application/IBuildInventoryItem.cs` (only implementor was `HomebrewProgram`; `BuildToolsInventory` itself stays, populated directly by `EssentialTools.MacOS.cs`).
### Files reduced to empty stubs
`ConfigAndData/Dependencies/`:
- `MacOS.cs` — `InitializeDependencies()` no-op (was Homebrew formula list + git fallback).
- `Linux.Arch.cs` — class kept (referenced by `distroMap`); package list removed.
- `Linux.Fedora.cs` — same.
- `Linux.Gentoo.cs` — same.
- `Linux.DebianCommon.cs` — common Debian/Ubuntu package list removed; `Flavor = "Debian"` kept.
- `Linux.UbuntuCommon.cs` — `libtoolPackages` + `NeedLibtool` virtual + `InitOS` override removed (all dead).
- `Linux.Debian.cs` — all per-version package lists (`packages`, `packagesPre10`, `packagesPreTrixie`, `packagesTrixieAndLater`, `packages10AndNewerBuildBots`) removed; release/codename detection (`EnsureVersionInformation`, `DebianUnstableVersionMap`, `IsDebian10OrNewer`, etc.) preserved as conservative scope.
- `Linux.Ubuntu.cs` — `preCosmicPackages`, `cosmicPackages`, `preDiscoPackages` lists + `NeedLibtool` override removed; `UbuntuRelease` + `EnsureVersionInformation` preserved.
- `Linux.Mint.cs` — `NeedLibtool` override removed (the property is gone from the base).
`ConfigAndData/Dependencies/Windows.cs` was already a no-op stub — no edit.
### Verification
Orphan audit (each `git grep -nw <Type> -- 'build-tools/xaprepare/*'` reports **0 hits**):
- `HomebrewProgram`, `PkgProgram`, `BrewRunner`, `PkgutilRunner`
- `ArchLinuxProgram`, `DebianLinuxProgram`, `FedoraLinuxProgram`, `GentooLinuxProgram`, `LinuxProgram`
- `IBuildInventoryItem`
Build:
```
dotnet build build-tools\xaprepare\xaprepare\xaprepare.csproj -c Debug
Build succeeded. 0 Warning(s) 0 Error(s)
```
### Out of scope (follow-up)
- Removing the abstract `OS.InitializeDependencies()` declaration and the surrounding `EnsureDependencies()` machinery from `OperatingSystems/OS.cs`.
- `VersionFetchers` / `ProgramVersionParser` / `RegexProgramVersionParser` / `SevenZipVersionParser` / `Extensions.DictionaryOfProgramVersionParser.cs` are kept — `Utilities.GetProgramVersion` still queries them from `Program.cs`, `ToolRunner.cs`, `EssentialTools.MacOS.cs`, and `OperatingSystems/MacOS.cs` (brew detection).
### Precedent
#11568, #11580, #11608, #11613, #11631, #11657, #11658, #11731, #11732, #11733, #11737, #11740, #11760

[xaprepare] Move XABuildConfig generation to AndroidBuildConfig.dll (#…
788d363
…11826)
## Summary
Moves `XABuildConfig.cs` generation out of `xaprepare` and into a new strong-named class library at `src/AndroidBuildConfig/AndroidBuildConfig.csproj` that produces `AndroidBuildConfig.dll`.
This continues the incremental removal of `xaprepare`, following the precedent set by `cmake-config.csproj` (#11760) and the recent batch #11568, #11580, #11608, #11613, #11631, #11731, #11732, #11733, #11737, #11740, #11803, #11821, #11825.
It also fixes a long-standing wart: previously `XABuildConfig.cs` was `<Compile Include>`'d into three different assemblies (`Xamarin.Android.Build.Tasks`, `Xamarin.ProjectTools`, and `Xamarin.Android.Build.Tests`), so every test that mentioned `XABuildConfig` produced a `CS0436` "type conflicts with imported type" warning — about **22** of them.
Wrapping the type in its own assembly collapses it to a single definition that every consumer references normally. After this change `Xamarin.Android.Build.Tests` builds with **7** warnings (none for `XABuildConfig`).
## How it works
`src/AndroidBuildConfig/AndroidBuildConfig.csproj`:
- `Microsoft.NET.Sdk` / `netstandard2.0`, strong-named with `product.snk`.
- `ProjectReference`s `Xamarin.Android.Tools.AndroidSdk` (for the `AndroidTargetArch` enum used by the template).
- `<UsingTask>`s `ReplaceFileContents`, `GitCommitHash`, and `GitBranch` from `$(PrepTasksAssembly)`, all with `TaskFactory="TaskHostFactory" Runtime="NET"` per repo convention.
- The `_GenerateXABuildConfig` target runs `BeforeTargets="BeforeCompile;CoreCompile"`, computes every substitution from MSBuild properties already exposed by `Configuration.props` (NDK major/minor/micro via `$(_XAAndroidNdkPkgRevision.Split('.'))`, API levels via `Split`/`Contains`, full commit hash via `GitCommitHash.CommitHash`, branch via `GitBranch.Branch`), and writes the file to `$(IntermediateOutputPath)XABuildConfig.cs`. The `<Compile Include>` lives inside the target so it resolves at execution time, when `IntermediateOutputPath` is final.
- `XABuildConfig` is now `public static class` instead of `internal static class`.
The three consumer csprojs lose their `<Compile Include="…XABuildConfig.cs" />` and now have a normal `<ProjectReference Include="…AndroidBuildConfig.csproj" />` (no `ReferenceOutputAssembly="False"`).
`build-tools/installers/create-installers.targets` ships `AndroidBuildConfig.dll` + `.pdb` alongside `Xamarin.Android.Build.Tasks.dll`.
## xaprepare cleanup
Removed dead code that only existed to feed the old `Get_XABuildConfig_cs` step:
- `Step_GenerateFiles.Get_XABuildConfig_cs` and its `GetMajor` / `GetMinor` locals
- `BuildInfo`: `NDKRevision`, `NDKVersionMajor`, `NDKVersionMinor`, `NDKVersionMicro`, `NDKVersion`, `XACommitHash`, `XABranch`, `GatherGitInfo`, `DetermineXACommitInfo`, `cachedNdkVersion`
- `Context`: the `if (SelectedScenario.NeedsGitBuildInfo) { await BuildInfo.GatherGitInfo … }` block
- `Scenario.NeedsGitBuildInfo` (and the `NeedsGitBuildInfo = true;` setters in `Scenario_Standard` and `Scenario_Required`)
- `BuildAndroidPlatforms.cs` — entire file (only contained constants used by the deleted code)
- `Utilities.ParseAndroidPkgRevision`
- `GitRunner.GetTopCommitHash` and `GitRunner.GetBranchName` (class retained — still used by `BuildInfo.DetermineLastVersionChangeCommit`)
## Files
**Added**
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
**Renamed/moved**
- `build-tools/scripts/XABuildConfig.cs.in` → `src/AndroidBuildConfig/XABuildConfig.cs.in` (`static class` → `public static class`)
**Modified**
- `src/Xamarin.Android.Build.Tasks/Xamarin.Android.Build.Tasks.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.ProjectTools/Xamarin.ProjectTools.csproj`
- `src/Xamarin.Android.Build.Tasks/Tests/Xamarin.Android.Build.Tests/Xamarin.Android.Build.Tests.csproj`
- `build-tools/installers/create-installers.targets`
- `build-tools/xaprepare/xaprepare/Steps/Step_GenerateFiles.cs`
- `build-tools/xaprepare/xaprepare/Application/BuildInfo.cs`
- `build-tools/xaprepare/xaprepare/Application/Context.cs`
- `build-tools/xaprepare/xaprepare/Application/Scenario.cs`
- `build-tools/xaprepare/xaprepare/Application/Utilities.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Standard.cs`
- `build-tools/xaprepare/xaprepare/Scenarios/Scenario_Required.cs`
- `build-tools/xaprepare/xaprepare/ToolRunners/GitRunner.cs`
- `build-tools/xaprepare/README.md`
**Deleted**
- `build-tools/xaprepare/xaprepare/ConfigAndData/BuildAndroidPlatforms.cs`
## Verification
- `AndroidBuildConfig.csproj`: 0 warnings, 0 errors.
- `Xamarin.Android.Build.Tasks.csproj`: 0 errors, 85 pre-existing unrelated warnings (none for `XABuildConfig`).
- `Xamarin.Android.Build.Tests.csproj`: 0 errors, **7** warnings — down from ~22; all `CS0436 XABuildConfig` conflicts eliminated.
- `xaprepare.csproj`: 0 warnings, 0 errors.
- Generated `XABuildConfig.cs` is semantically identical to the pre-change xaprepare output. The only token difference is the intentional `static class` → `public static class`; everything else (NDK split, API-level major/minor split, supported-ABIs semicolon list, full commit hash, branch name, etc.) matches the previous baseline byte-for-byte.

[xaprepare] Move cgmanifest.json generation from xaprepare to YAML (#…
c7c9458
…11825)
Continues the incremental removal of `xaprepare` by moving the
`cgmanifest.json` generator out of the C# step
`Step_GenerateCGManifest` and into a YAML `pwsh:` step that runs only
on CI.
The file is consumed exclusively by the Azure DevOps Component
Governance Detection task (auto-injected on internal pipelines by
`eng/common/core-templates/job/job.yml`). It is not consumed by any
in-repo build target, so generating it from the C# Prepare step is no
longer necessary.
We cannot drop the file outright: `eng/common` ships CG infrastructure
but it is not yet wired to auto-discover submodules in our pipelines,
so the explicit `cgmanifest.json` is still the source of truth.
Files:
* Added: `build-tools/automation/yaml-templates/generate-cgmanifest.yaml`
* Modified: `build-windows-steps.yaml`, `build-macos-steps.yaml`,
`build-linux-steps.yaml`, `commercial-build.yaml` (call the new
template after the Prepare/`make jenkins` step)
* Modified: `Scenario_Standard.cs` (drop registration)
* Modified: `GitRunner.cs` (remove now-unused `ConfigList` and
`SubmoduleStatus` methods)
* Deleted: `Step_GenerateCGManifest.cs`
Verification: byte-for-byte diff of the YAML-generated
`cgmanifest.json` against the previous C# output on Debug:
Baseline=3144 New=3144
Total byte differences: 0
Precedent PRs in this stream: #11568, #11580, #11608, #11613,
#11631, #11731, #11732, #11733, #11737, #11740, #11760, #11803,
#11821.
### Simplify generate-cgmanifest.yaml using ConvertTo-Json
Replace the hand-rolled StringBuilder JSON emission with PowerShell's
`ConvertTo-Json`. The output is no longer byte-identical to the
previous C# output (2-space indent instead of 4, and slightly
different whitespace), but it is still valid JSON matching the
component-detection-manifest schema. The Azure DevOps Component
Governance Detection task parses the file, so formatting does not
matter.

[xaprepare] Delete redundant Windows JdkInfo.props generator (#11946)
e18dc17
On Windows, xaprepare's Step_GenerateFiles.Windows.cs writes
external/Java.Interop/bin/Build$(Configuration)/JdkInfo.props from
build-tools/xaprepare/xaprepare/Resources/JdkInfo.Windows.props.in.
But this file is immediately overwritten. The PrepareWindows.targets
Prepare flow runs, in order:
1. `dotnet xaprepare -a` — writes JdkInfo.props (this code).
2. `MSBuild Xamarin.Android.BootstrapTasks.sln` — does not read JdkInfo.props.
3. `MSBuild src/workloads/workloads.csproj` — does not read JdkInfo.props.
4. `CallTarget PrepareJavaInterop` → `dotnet build -t:Prepare Java.Interop.sln`
→ external/Java.Interop/build-tools/scripts/Prepare.targets → runs the
`JdkInfo` MSBuild task → overwrites JdkInfo.props with its own generated
content.
Nothing between step 1 and step 4 reads the file, and Java.Interop's Prepare
always regenerates it. Now that external/Java.Interop is in-tree, we can
safely delete the redundant write.
This is the smallest-diff removal:
* Delete Step_GenerateFiles.Windows.cs (the AddOSSpecificSteps partial).
* Delete Resources/JdkInfo.Windows.props.in.
* In Step_GenerateFiles.cs, drop the `partial void AddOSSpecificSteps`
declaration and collapse GetFilesToGenerate so `atBuildStart == false`
returns null. Ctor surface (atBuildStart, onlyRequired) is unchanged so
Scenario_Required.cs is unaffected.
* In Scenario_Standard.cs, remove the AddEndSteps override — the only
thing it did was schedule the now-empty Step_GenerateFiles(atBuildStart:
false).
Preserved (future slices will address these):
* Get_Configuration_OperatingSystem_props (D1).
* OperatingSystems/*.cs and Context.OS.* surface.
* PrepareWindows.targets, DotNet.targets, Java.Interop's Prepare.targets.
Verification:
* dotnet build build-tools/xaprepare/xaprepare/xaprepare.csproj -c Debug
→ Build succeeded. 0 Warning(s). 0 Error(s).
* build.cmd -t:Prepare -c Debug (Windows, cold tree) → succeeds; the file
external/Java.Interop/bin/BuildDebug/JdkInfo.props exists.
* Compare-Object of the resulting JdkInfo.props before vs after this
change → byte-identical (1493 bytes, SHA256
DE59A8061B7657831788FFED7BC1DEECA442E9181605083A4553DE7AC8C003A1),
confirming Java.Interop's overwrite is what always ends up on disk.
* Grep audit under build-tools/xaprepare/: no remaining references to
Step_GenerateFiles.Windows, JdkInfo.Windows.props.in, or
AddOSSpecificSteps.

[xaprepare] Delete Configuration.OperatingSystem.props generator and …
be5272c
…xaprepare project (#11959)
Follow-up to #11956, which moved the JDK half of `Configuration.OperatingSystem.props` to Java.Interop's `JdkInfo.props`. The remaining NDK / OS-info half has zero real consumers, so this PR:
1. Deletes the last generator template (`Configuration.OperatingSystem.props.in`).
2. Cascades through `Step_GenerateFiles`, both `Scenario_*` classes (which now had zero steps), and every supporting `OperatingSystems/`, `Context.*OS.cs`, `EssentialTools.*`, `ToolRunners/*`, `Configurables.*`, `Application/*`, and `Main.cs` file that only existed to feed the scenarios.
3. Deletes the whole `build-tools/xaprepare/` project.
4. Patches every integration point (`Makefile`, `PrepareWindows.targets`, `BuildEverything.mk`, CI YAML, docs) so `build.cmd -t:Prepare` and `make prepare` still work end-to-end.
## `Configuration.OperatingSystem.props.in` placeholder audit
| Placeholder | Consumers outside the `.in` file | Action |
| --- | --- | --- |
| `HostOsName` | none | drop |
| `HostOsFlavor` | none | drop |
| `HostOsRelease` | none | drop |
| `HostBits` | none (`ArchiveBase.HostBits` in `src/Xamarin.Installer.AndroidSDK/` is an unrelated C# property) | drop |
| `NdkLlvmTag` | none (the NDK toolchain OS tag is resolved elsewhere via `_NdkToolchainOSTag` in `androidsdk.targets`) | drop |
| `HostCpuCount` | only `Configuration.props:72` via `$(MakeConcurrency)` | drop |
## `$(MakeConcurrency)` audit
The only definition was `Configuration.props:72`. A repo-wide grep of `.targets`, `.props`, `.projitems`, `Makefile`, and `.mk` files found zero consumers of the MSBuild property. The `MakeConcurrency` hits under `build-tools/xaprepare/` were an unrelated C# `Context.MakeConcurrency` property.
**Result:** dropped the `MakeConcurrency` MSBuild property entirely (no `$([System.Environment]::ProcessorCount)` replacement needed) and removed the `$(MakeConcurrency)` bullet in `Documentation/building/configuration.md`.
## xaprepare integration audit (grep-confirmed, patched here)
| Location | Change |
| --- | --- |
| `build-tools/xaprepare/` (entire tree) | **deleted** — 86 tracked files |
| `Configuration.props` | dropped `<Import>` of the generated OS props, dropped `MakeConcurrency`, tidied the "between xaprepare and package creation tools" comment |
| `.gitignore` | dropped `Configuration.OperatingSystem.props` |
| `build-tools/scripts/PrepareWindows.targets` | removed `_XAPrepareExe`, `_XAPrepareStandardArgs`, `_BuildXAPrepare` target, and the `Exec dotnet $(_XAPrepareExe)` line. Repointed `Prepare` at `_InstallDotNet`. Kept the space-in-path guard, BootstrapTasks / workloads MSBuilds, and `PrepareJavaInterop` |
| `Makefile` | dropped `PREPARE_PROJECT`, `PREPARE_NET_FX`, `PREPARE_ARGS`, `PREPARE_MSBUILD_FLAGS`, `PREPARE_SCENARIO`, `PREPARE_CI_PR`, `PREPARE_CI`, `_PREPARE_CI_MODE_*`, `_PREPARE_ARGS`, and all their conditionals. Dropped the `dotnet run --project xaprepare.csproj` line from `prepare`. Deleted the `prepare-help` target |
| `build-tools/scripts/BuildEverything.mk` | `jenkins` no longer branches on `PREPARE_CI_PR`/`PREPARE_CI`; just `$(MAKE) prepare && $(MAKE) leeroy` |
| `.github/workflows/copilot-setup-steps.yml` | dropped now-unused `PREPARE_CI=1` |
| `build-tools/automation/azure-pipelines-apidocs.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-linux-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/build-macos-steps.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/commercial-build.yaml` | dropped `PREPARE_CI=1` |
| `build-tools/automation/yaml-templates/copy-extra-result-files.yaml` | dropped `**/Configuration.OperatingSystem.props` glob and the stale `Step_CopyExtraResultFilesForCI` xaprepare-step comment |
| `build-tools/automation/yaml-templates/generate-cgmanifest.yaml` | dropped the stale `Step_GenerateCGManifest` xaprepare-step comment |
| `build-tools/automation/yaml-templates/setup-jdk-variables.yaml` | renamed `$xaPrepareJdkPath` → `$xaJdkPath` for hygiene |
| `Documentation/workflow/HowToAddNewApiLevel.md` | rewrote the "Add New Platform" section to point at `<_PlatformPackage>` entries in `src/androidsdk/androidsdk.targets` instead of `AndroidToolchain.cs`; updated the `--android-sdk-platforms=all` recipe to `dotnet-local build src/androidsdk/androidsdk.csproj -p:AndroidSdkPlatforms=all` |
| `Documentation/building/unix/dependencies.md` | JDK-version link now points at `$(MicrosoftOpenJDKVersion)` in `/Configuration.props` instead of the deleted `Configurables.cs` |
| `Documentation/building/configuration.md` | removed the `$(MakeConcurrency)` bullet |
**Historical breadcrumb comments left as-is** (still accurate and useful for git-archaeology):
- `.github/skills/update-tpn/SKILL.md`
- `src/AndroidBuildConfig/AndroidBuildConfig.csproj`
- `src/androidsdk/androidsdk.targets`
- `src/native/cmake-config/cmake-config.csproj`
- `src/workloads/workloads.csproj`
## Verification
- `build.cmd Prepare` — succeeded end-to-end on Windows (0 warnings, 0 errors). The trimmed `Prepare` target ran through `_InstallDotNet`, the space-in-path guard, `Xamarin.Android.BootstrapTasks.sln`, `src/workloads/workloads.csproj`, and `PrepareJavaInterop`.
- `dotnet build src\Xamarin.Android.Build.Tasks\Xamarin.Android.Build.Tasks.csproj -c Debug` — 0 errors (93 pre-existing warnings from `src/Mono.Android/` and generated MCW, unrelated to this change).
- Repo-wide grep for `HostOsName`, `HostOsFlavor`, `HostOsRelease`, `HostCpuCount`, `NdkLlvmTag`, and the MSBuild `MakeConcurrency` property — clean.
- Repo-wide grep for `xaprepare` — clean apart from the five intentional historical breadcrumb comments listed above.
