[mobile] .NET 11 mobile runtime configuration updates by kotlarmilos · Pull Request #11632 · dotnet/android

kotlarmilos · 2026-06-11T14:59:06Z

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.

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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

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.

Show a summary per file

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:

Introduce the error you have here: dotnet/sdk#54713 (just temporarily put it in this workload to test)
See how red CI is
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)

-# MAUI Tests Stage
- stage: maui_tests
-  displayName: MAUI Tests
-  dependsOn: mac_build
-  condition: and(succeeded(), ne(variables['SkipTestStages'], 'true'))
-  jobs:


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.

Why are we bumping .NET the same time?

I would keep this.

I think you'll have to restore these for the src/native folder to be able to build.

This is a target we use to install MAUI on top of a local build -- we shouldn't remove it.
