✨ Convert to binary module by Copilot · Pull Request #114 · JustinGrote/ModuleFast

Copilot · 2026-03-20T18:39:52Z

Install progress was a static 50% during the entire install phase, with no indication of how many modules were being installed or how far along the process was.

Changes

ModuleFastInstaller.InstallModulesAsync: Added Action<ModuleFastInfo>? onModuleInstalled callback parameter, invoked synchronously on the completing thread after each successful install. Uses Action<T> (not IProgress<T>) to avoid SynchronizationContext marshalling.
InstallModuleFastCommand: Progress now updates per-module using Interlocked.Increment — shows Installing X/N Modules (P%) in real time as parallel installs complete. Percentage uses (int)(done * 100.0 / total) to avoid integer truncation.

Progress now looks like:

Installing 3/10 Modules (30%)
Installing 7/10 Modules (70%)
Installing 10/10 Modules (100%)

@copilot Convert the following powershell functions and any dependent functions into C# Cmdlets:
Install-ModuleFast
Get-ModuleFastPlan
Clear-ModuleFastCache
Install-ModuleFastHelper
Import-ModuleManifest
ConvertFrom-PSResourceGet
Get-ModuleInfoAsync
Add-DestinationToPSModulePath
Find-LocalModule
ConvertFrom-RequiredSpec
Select-RequiredSpecFileType
Read-RequiredSpecFile
ConvertFrom-ModuleManifest
Approve-Action
Get-PSDefaultModulePath

- Add InstallModuleFastCommand, GetModuleFastPlanCommand, ClearModuleFastCacheCommand, ImportModuleManifestCommand cmdlets - Add ModuleFastPlanner (async HTTP planning with Task.WhenAll) - Add ModuleFastInstaller (parallel download+extract, no runspaces) - Add ModuleManifestReader (handles dynamic .psd1 manifests) - Add LocalModuleFinder (searches PSModulePaths for installed modules) - Add SpecFileReader (ModuleFast/PSResourceGet/PSDepend spec file formats) - Add PathHelper (PSModulePath management, profile updates) - Add ModuleFastCache (singleton ConcurrentDictionary request cache) - Add NuGetModels (JSON models for NuGet v3 Registration API) - Update ModuleFastInfo: make ModuleVersion, Location, Guid settable; IsLocal computed - Update ModuleFastClient: add PSCredential support, ToAuthHeader, HTTP/3 - Update ModuleFast.psm1: simplified to DLL load + type accelerators only - Update ModuleFast.psd1: FunctionsToExport=@(), CmdletsToExport with all 4 cmdlets - Update ModuleFast.tests.ps1: remove InModuleScope wrapper (Import-ModuleManifest is now a public cmdlet) - Add SpecFileType and InstallScope enums in C# Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

@copilot Convert the following powershell functions and any dependent functions into C# Cmdlets:
Install-ModuleFast
Get-ModuleFastPlan...

Done in commit 4e1f6bf. All 15 functions (plus their helpers) are now C# binary cmdlets/classes:

PowerShell function	C# equivalent
`Install-ModuleFast`	`InstallModuleFastCommand` — all 3 param sets
`Get-ModuleFastPlan`	`GetModuleFastPlanCommand`
`Clear-ModuleFastCache`	`ClearModuleFastCacheCommand`
`Import-ModuleManifest`	`ImportModuleManifestCommand` + `ModuleManifestReader`
`Install-ModuleFastHelper`	`ModuleFastInstaller` — uses `Task.WhenAll`, no runspaces/ThreadJob
`Get-ModuleInfoAsync`	`ModuleFastPlanner.GetModuleInfoAsync` + `GetCachedStringAsync`
`Find-LocalModule`	`LocalModuleFinder.FindLocalModule`
`ConvertFrom-RequiredSpec`	`SpecFileReader.ConvertFromRequiredSpec`
`Select-RequiredSpecFileType`	`SpecFileReader.SelectRequiredSpecFileType`
`Read-RequiredSpecFile`	`SpecFileReader.ReadRequiredSpecFile`
`ConvertFrom-PSResourceGet`	`SpecFileReader.ConvertFromPSResourceGet`
`Add-DestinationToPSModulePath`	`PathHelper.AddDestinationToPSModulePath`
`Get-PSDefaultModulePath`	`PathHelper.GetPSDefaultModulePath`
`Approve-Action`	`PathHelper.ApproveAction`
`ConvertFrom-PSDepend`	`SpecFileReader.ConvertFromPSDepend`

ModuleFast.psm1 is now just DLL loading + type accelerator registration. The planning loop uses Task.WhenAny and installation uses Task.WhenAll for parallel downloads and extraction.

@copilot Reconfigure to use Artifacts Output Layout and Central Package Management

@copilot Reconfigure to use Artifacts Output Layout and Central Package Management

Done in commit 4da8061.

Artifacts Output Layout (Directory.Build.props):

UseArtifactsOutput=true — all build outputs now land in artifacts/bin/ModuleFast/{debug,release}/ instead of src/ModuleFast/bin/
ModuleFast.psm1 probes artifacts/bin/ModuleFast/debug/, then release/, then falls back to the classic deployed bin/ModuleFast/ path
ModuleFast.build.ps1: BuildCSharp drops the -o flag; CopyFiles reads from artifacts/bin/ModuleFast/release/ when staging the module

Central Package Management (Directory.Packages.props):

ManagePackageVersionsCentrally=true with Microsoft.PowerShell.SDK 7.4.6 and NuGet.Versioning 6.8.0
ModuleFast.csprojPackageReference entries no longer carry Version attributes
