Description

Remove the Mono mobile test legs from build-tools, and drop the Microsoft.NET.Workload.Mono.Toolchain manifest dependency from eng/Version.Details.xml and eng/Versions.props.

Validation pipelines (must pass): dotnet-android (devdiv pipeline 12278) PR build.

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.

TODO before merge: revert the global.json / Version.Details.xml / Versions.props pins and the NuGet.config feed back to the official VMR versions and the main feed.

Pull request overview

This PR updates the repo’s .NET 11 “mobile runtime” configuration by removing Mono mobile-related dependencies (notably the Mono toolchain workload manifest) and pruning CI/build tooling paths that were exercising Mono-based mobile workloads/runtimes, while temporarily pinning to a specific .NET 11 preview SDK/feed to validate the new configuration.

Changes:

  • Remove Mono toolchain workload manifest dependency/version plumbing from eng/* and xaprepare.
  • Remove Mono-runtime test lanes (and MAUI integration test stages) from build-tools Azure Pipelines templates.
  • Update restore inputs for validation (temporary): add general-testing feed and pin .NET 11 preview versions.

File Description
NuGet.config Adds the general-testing feed for temporary validation restores.
eng/Versions.props Moves to a pinned .NET 11 preview SDK version; removes Mono toolchain manifest version properties.
eng/Version.Details.xml Updates .NET dependency versions/SHA; removes Mono toolchain manifest dependency entry.
build-tools/xaprepare/xaprepare/xaprepare.targets Stops generating replacements for removed Mono manifest properties.
build-tools/xaprepare/xaprepare/Steps/Step_InstallDotNetPreview.cs Removes Mono toolchain manifest copy logic; keeps Emscripten manifest copy.
build-tools/xaprepare/xaprepare/package-download.proj Removes Mono runtime pack downloads and Mono toolchain manifest downloads (now only Android CoreCLR runtime + Emscripten manifests).
build-tools/xaprepare/xaprepare/ConfigAndData/Configurables.cs Removes Mono toolchain manifest package directory helpers.
build-tools/xaprepare/xaprepare/Application/Properties.Defaults.cs.in Removes default properties for Mono manifest/version variables.
build-tools/xaprepare/xaprepare/Application/KnownProperties.cs Removes Mono manifest/version property names.
build-tools/scripts/DotNet.targets Removes MAUI workload install step from the helper targets.
build-tools/create-packs/ConfigureLocalWorkload.targets Simplifies “ConfigureLocalWorkload” to only install the Android manifest (no dependency-install workaround).
build-tools/automation/yaml-templates/variables.yaml Removes the RunMAUITestJob variable.
build-tools/automation/yaml-templates/stage-package-tests.yaml Removes Mono-runtime APK instrumentation legs (Interpreter/NoAot/LLVM/etc).
build-tools/automation/azure-pipelines.yaml Removes MAUI test stage and dependency edges from the private pipeline definition.
build-tools/automation/azure-pipelines-public.yaml Removes MAUI test stage from the public pipeline definition.

Overall, I'd take a different approach to this one:

  1. Introduce the error you have here: dotnet/sdk#54713 (just temporarily put it in this workload to test)
  2. See how red CI is
  3. Remove tests & iterate until green

The on-device tests you removed here looks right.

But we also have a lot of MSBuild tests that parameterize on MonoVM/CoreCLR/NativeAOT that would need to run for CoreCLR/NativeAOT only.

Then we can remove the error you have in step 1 (that can come from dotnet/sdk)

This stage tests the MAUI pipeline with our product, doesn't seem like that should be deleted?

Because it is a main <-> net11.0 build, it does break sometimes until changes land in dotnet/maui/net11.0, so that's ok if this is the case here.

Restored. Kept the MAUI Tests stage in both pipeline files. Agreed it is fine for it to break until the matching changes land in net11.0, so leaving it in place.

Why are we bumping .NET the same time?

Temporary validation pin to the .NET 11 test build so the repo can be exercised against the updated SDK. Not a permanent .NET bump.

That is what maestro is for; I wouldn't do this here.

The MAUI integration stage installs the full maui workload, which pulls
mobile runtime workloads that are no longer produced for .NET 11. Remove
the stage from the public and internal pipelines and drop the now-unused
RunMAUITestJob variable.

…able

Address review feedback: the native build and MAUI-on-local-build flow still
require the Mono runtime pack downloads and workload-install targets, so restore
package-download.proj, DotNet.targets, Step_InstallDotNetPreview, the xaprepare
property plumbing, the maui_tests stage, and the RunMAUITestJob variable. The PR
now changes only the Mono mobile instrumentation test legs in
stage-package-tests.yaml plus the temporary validation pins.

Surface the unsupported Mono mobile runtime build error directly in the
workload to validate that no Mono mobile build paths remain in CI.

Validation now happens through the temporary Mono mobile runtime build
error in the workload, so the pinned SDK version and validation package
feed are no longer needed.
