Description

Part of splitting #125439 into smaller, self-contained PRs.

The Debug AllSubsets_CoreCLR_Smoke jobs for tvOS, iOSSimulator, and MacCatalyst are unstable and tracked in #124344. In the corresponding Release jobs, enable EnableAggressiveTrimming and EnableAdditionalTimezoneChecks so CI tests the trimmed library build path that ships to customers.

Fix trimming test exclusions for iOS/tvOS simulator CoreCLR builds (#…
cc3bb88
…127465)
> [!NOTE]
> This PR was AI/Copilot-generated.
## Summary
The aggressive trimming test exclusion condition in
\src/libraries/tests.proj\ only checked for \ios\, \ vos\, and
\maccatalyst\ TargetOS values, missing \iossimulator\ and \
vossimulator\. This caused trimming-sensitive tests to run — and fail —
on iOS CoreCLR simulator Release builds where
\EnableAggressiveTrimming=true\ was recently enabled by #127054.
## Root Cause
PR #127054 (April 20) enabled \EnableAggressiveTrimming=true\ for iOS
CoreCLR simulator Release builds. Aggressive trimming strips EventSource
reflection metadata (\ParameterInfo[]\), causing \PayloadNames\ to throw
\NullReferenceException\ when accessed.
The test exclusion at line 381 of \	ests.proj\ had three clauses:
1. Non-browser AOT builds → catches Mono AOT ✅
2. Browser/WASM AOT builds → catches WASM ✅ 3. Apple mobile with \BuildTestsOnHelix=true\ → **only checked \ios\, \
vos\, \maccatalyst\** ❌
For simulator builds, \TargetOS\ is \iossimulator\ or \ vossimulator\
(not \ios\/\ vos\), confirmed by \�ng/RuntimeIdentifier.props:61-63\. So
the exclusion didn't match, and 8+ trimming-sensitive tests ran and
failed with NRE.
## Fix
Replace the explicit TargetOS list with the \TargetsAppleMobile\
property (defined in \�ng/OSArch.props\), which covers all five Apple
mobile targets (\ios\, \iossimulator\, \ vos\, \ vossimulator\,
\maccatalyst\) and is already used elsewhere in the same file (lines
303, 337, 654, 765).
Fixes#127449
Related: #127448 (DI/Hosting failures on same build — same root cause)

Fix trimming test exclusions for iOS/tvOS simulator CoreCLR builds (#…
cc3bb88
…127465)
> [!NOTE]
> This PR was AI/Copilot-generated.
## Summary
The aggressive trimming test exclusion condition in
\src/libraries/tests.proj\ only checked for \ios\, \ vos\, and
\maccatalyst\ TargetOS values, missing \iossimulator\ and \
vossimulator\. This caused trimming-sensitive tests to run — and fail —
on iOS CoreCLR simulator Release builds where
\EnableAggressiveTrimming=true\ was recently enabled by #127054.
## Root Cause
PR #127054 (April 20) enabled \EnableAggressiveTrimming=true\ for iOS
CoreCLR simulator Release builds. Aggressive trimming strips EventSource
reflection metadata (\ParameterInfo[]\), causing \PayloadNames\ to throw
\NullReferenceException\ when accessed.
The test exclusion at line 381 of \	ests.proj\ had three clauses:
1. Non-browser AOT builds → catches Mono AOT ✅
2. Browser/WASM AOT builds → catches WASM ✅ 3. Apple mobile with \BuildTestsOnHelix=true\ → **only checked \ios\, \
vos\, \maccatalyst\** ❌
For simulator builds, \TargetOS\ is \iossimulator\ or \ vossimulator\
(not \ios\/\ vos\), confirmed by \�ng/RuntimeIdentifier.props:61-63\. So
the exclusion didn't match, and 8+ trimming-sensitive tests ran and
failed with NRE.
## Fix
Replace the explicit TargetOS list with the \TargetsAppleMobile\
property (defined in \�ng/OSArch.props\), which covers all five Apple
mobile targets (\ios\, \iossimulator\, \ vos\, \ vossimulator\,
\maccatalyst\) and is already used elsewhere in the same file (lines
303, 337, 654, 765).

Fix trimming test exclusions for iOS/tvOS simulator CoreCLR builds (#…
cc3bb88
…127465)
> [!NOTE]
> This PR was AI/Copilot-generated.
## Summary
The aggressive trimming test exclusion condition in
\src/libraries/tests.proj\ only checked for \ios\, \ vos\, and
\maccatalyst\ TargetOS values, missing \iossimulator\ and \
vossimulator\. This caused trimming-sensitive tests to run — and fail —
on iOS CoreCLR simulator Release builds where
\EnableAggressiveTrimming=true\ was recently enabled by #127054.
## Root Cause
PR #127054 (April 20) enabled \EnableAggressiveTrimming=true\ for iOS
CoreCLR simulator Release builds. Aggressive trimming strips EventSource
reflection metadata (\ParameterInfo[]\), causing \PayloadNames\ to throw
\NullReferenceException\ when accessed.
The test exclusion at line 381 of \	ests.proj\ had three clauses:
1. Non-browser AOT builds → catches Mono AOT ✅
2. Browser/WASM AOT builds → catches WASM ✅ 3. Apple mobile with \BuildTestsOnHelix=true\ → **only checked \ios\, \
vos\, \maccatalyst\** ❌
For simulator builds, \TargetOS\ is \iossimulator\ or \ vossimulator\
(not \ios\/\ vos\), confirmed by \�ng/RuntimeIdentifier.props:61-63\. So
the exclusion didn't match, and 8+ trimming-sensitive tests ran and
failed with NRE.
## Fix
Replace the explicit TargetOS list with the \TargetsAppleMobile\
property (defined in \�ng/OSArch.props\), which covers all five Apple
mobile targets (\ios\, \iossimulator\, \ vos\, \ vossimulator\,
\maccatalyst\) and is already used elsewhere in the same file (lines
303, 337, 654, 765).
