[mobile] .NET 11 mobile runtime configuration updates by kotlarmilos · Pull Request #129293 · dotnet/runtime

kotlarmilos · 2026-06-11T14:54:17Z

Description

Remove the Mono mobile test legs from the runtime CI pipelines:

eng/pipelines/runtime.yml: the Mono mobile smoke legs (android, iossimulator, maccatalyst), the mobile platforms dropped from MonoAOTOffsets (kept browser_wasm and wasi_wasm), and tvossimulator_arm64 dropped from the Mono AllSubsets_Mono build leg.
eng/pipelines/extra-platforms/runtime-extra-platforms-{ioslike,ioslikesimulator,maccatalyst}.yml: the Mono AllSubsets_Mono_RuntimeTests legs.
eng/pipelines/extra-platforms/runtime-extra-platforms-{android,androidemulator}.yml: the Mono libraries-test and runtime-test legs.
eng/pipelines/performance/perf-build.yml: the mono_arm64_android and mono_arm64_ios build types are removed entirely (parameters and build legs), not left as disabled parameters.

WebAssembly Mono, desktop Mono, and the CoreCLR/NativeAOT mobile legs are untouched.

Validation pipelines (must pass): runtime, runtime-extra-platforms. wasm legs stay green.

Validation pins (temporary): pinned to .NET 11 test build 11.0.100-preview.6.26310.106 (AzDO dotnet-unified-build run 2996804, BAR 318158, source dotnet/dotnet@8d5d82abe13, branch dev/update-sdk-mobile-stage2) and the public general-testing NuGet feed, so CI exercises the SDK with the Mono mobile workloads and RIDs removed.

Related performance changes: dotnet/performance#5240

TODO before merge: revert the global.json SDK pin and the NuGet.config feed back to the official VMR version and the main feed.

Pull request overview

Updates the .NET 11 mobile-related CI configuration by reducing Mono mobile coverage in runtime pipelines and adjusting repo-level SDK / restore inputs to validate against a temporary SDK + feed combination.

Changes:

Add the general-testing NuGet feed to the repo restore sources.
Pin global.json to a specific .NET 11 preview SDK version for validation.
Remove Mono mobile library-test legs from runtime.yml / extra-platform pipelines, and disable Mono mobile perf-build legs by default.

Show a summary per file

File	Description
NuGet.config	Adds `general-testing` package source (temporary validation input).
global.json	Pins repo SDK/tooling to 11.0.100-preview.6.26310.106 (temporary validation input).
eng/pipelines/runtime.yml	Removes Mono mobile library-test legs from the main runtime pipeline (keeps WASM/CoreCLR/NativeAOT legs).
eng/pipelines/performance/perf-build.yml	Disables Mono Android/iOS perf build legs by default (still available when enabled).
eng/pipelines/extra-platforms/runtime-extra-platforms-maccatalyst.yml	Removes Mono MacCatalyst libraries-test legs.
eng/pipelines/extra-platforms/runtime-extra-platforms-ioslikesimulator.yml	Removes Mono iOS-simulator libraries-test legs.
eng/pipelines/extra-platforms/runtime-extra-platforms-ioslike.yml	Removes Mono tvOS libraries-test legs.

NuGet.config:14

Adding general-testing as an always-on package source can change restore behavior (e.g., pulling newer prerelease packages) for both CI and local builds. If this is meant to be a temporary validation pin, consider adding an inline note here to reduce the risk of accidentally merging with the extra feed still enabled.

Remove the Mono mobile runtime-test legs (tvos, iossimulator, maccatalyst) and the Mono mobile libraries-test legs (android devices and emulator) from the extra-platforms pipelines, and remove the Mono mobile build types from the perf build instead of leaving them as disabled parameters. CoreCLR, NativeAOT, desktop Mono and wasm Mono legs are unchanged. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Remove the run_android_mono_jit and run_android_mono_aot parameters, their include-gate references, and the forwarding overrides, matching the removal of the Android Mono JIT/AOT job groups in runtime-perf-jobs.yml. Android CoreCLR and desktop Mono perf toggles are kept. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

… templates The iOS simulator and MacCatalyst CoreCLR jobs referenced isiOSLikeOnlyBuild, which is not declared in those templates' parameters and is not passed by runtime-extra-platforms.yml. Use each template's declared flag (isiOSLikeSimulatorOnlyBuild and isMacCatalystOnlyBuild) so the templates are self-contained and gated consistently with their sibling jobs.

Copilot Code Review

Holistic Assessment

Motivation: Justified. .NET 11 is transitioning mobile platforms from Mono to CoreCLR/NativeAOT. Removing the Mono mobile CI test legs, smoke tests, AOT offsets, and perf build types is the expected follow-through for that transition. WebAssembly Mono and desktop Mono legs are correctly preserved.

Approach: Correct. The PR surgically removes only Mono-flavored mobile legs (Android, iOS, tvOS, MacCatalyst) across the runtime, extra-platforms, and performance pipelines while leaving all CoreCLR/NativeAOT mobile legs untouched. The commit also fixes pre-existing parameter flag mismatches (isiOSLikeOnlyBuild → isiOSLikeSimulatorOnlyBuild / isMacCatalystOnlyBuild) that were exposed by the removal.

Summary: ✅ LGTM. The changes are clean, focused, and consistent. All CoreCLR/NativeAOT mobile legs remain intact. Parameter flags are now correctly aligned between callers and templates. The temporary validation pins (global.json SDK and NuGet.config feed) have been reverted in commit 1edbc19. One minor follow-up suggestion below regarding dead code in a downstream template.

Detailed Findings

✅ Pipeline removals — Correct and complete

All Mono mobile test legs have been cleanly removed across all affected files:

File	What was removed
`runtime.yml`	Mono smoke legs (android, iossimulator, maccatalyst); MonoAOTOffsets for `android_x64`, `ios_arm64`, `maccatalyst_x64`; `tvossimulator_arm64` from `AllSubsets_Mono` build
`runtime-extra-platforms-android.yml`	Mono `AllSubsets_Mono` library test leg
`runtime-extra-platforms-androidemulator.yml`	Mono runtime tests (minijit + interpreter) and library test legs
`runtime-extra-platforms-ioslike.yml`	tvOS Mono library + runtime test legs
`runtime-extra-platforms-ioslikesimulator.yml`	iOSSimulator Mono library + runtime test legs
`runtime-extra-platforms-maccatalyst.yml`	MacCatalyst Mono library, runtime, and AppSandbox test legs
`perf-build.yml`	`mono_arm64_android` and `mono_arm64_ios` parameters and all build-leg references
`perf-gapfill.yml`	`run_android_mono_jit` and `run_android_mono_aot` parameters and gate references
`perf-build-jobs.yml`	`monoAndroid: true` removed from `perf-mono-build-jobs.yml` invocation

All remaining mobile legs are runtimeFlavor: coreclr (CoreCLR or NativeAOT). No empty jobs: sections were created.

✅ Parameter flag fix — Correct

The PR fixes two pre-existing parameter mismatches exposed by the Mono leg removal:

runtime-extra-platforms-ioslikesimulator.yml: isiOSLikeOnlyBuild → isiOSLikeSimulatorOnlyBuild (matches what runtime-extra-platforms.yml passes)
runtime-extra-platforms-maccatalyst.yml: isiOSLikeOnlyBuild → isMacCatalystOnlyBuild (matches what runtime-extra-platforms.yml passes)

Verified that all five sub-template parameter flags now align with their caller in runtime-extra-platforms.yml.

✅ Temporary validation pins — Reverted

Commit 1edbc19 reverts both the global.json SDK pin and the NuGet.config general-testing feed, as tracked in the PR description TODO.

💡 Dead code in `perf-mono-build-jobs.yml` — Follow-up cleanup

eng/pipelines/performance/templates/perf-mono-build-jobs.yml still declares monoAndroid (line 6) and monoAndroidPacks (line 7) parameters with false defaults, and retains the corresponding job blocks (lines 107–142). No caller sets these to true anymore (perf-build-jobs.yml no longer passes monoAndroid: true; perf-bdn-build-jobs.yml passes monoAndroidPacks: true but is gated behind ${{ if false }}:). These are harmless dead code but could be cleaned up in a follow-up for consistency. Not a blocker.
