kotlarmilos · 2025-11-03T16:37:21Z

Description

This PR updates the MAUI iOS samples to use .NET 11 workloads and adds support for running with the CoreCLR interpreter.

Changes

Temporarily disabled MAUI workloads until .NET 11 packages are available (Enable MAUI samples when TargetFramework=net11.0 becomes available #5055)
Updated the build to use the latest .NET 11 SDK and workload packages
Added support for CoreCLR interpreter scenarios in MAUI iOS benchmarks

Validation

Test run: https://dev.azure.com/dnceng/internal/_build/results?buildId=2862740&view=results

Out of scope

Device startup measurements are currently unreliable and may fail due to a device connection issue. This is a known issue and is being handled separately by the engineering team.

Contributes to dotnet/runtime#120054

Pull request overview

This PR updates MAUI iOS samples to use .NET 11 workloads and adds support for running with the CoreCLR interpreter. The changes temporarily disable certain MAUI scenarios until .NET 11 packages are available, update SDK and workload package versions, and introduce CoreCLR interpreter configuration options.

Removes the generic --nativeaot command-line argument in favor of MSBuild properties for more granular runtime and codegen control
Adds CoreCLR interpreter support for iOS benchmarks alongside existing Mono and NativeAOT configurations
Updates macOS/iOS SDK dependencies from version 18.5 to 26.1 with .NET 11 compatibility

To double check, the new --break-system-packages will hopefully allow these calls to succeed on OSX because without it we get an error about the environment being externally managed?

Yes, it fixes the failures in #5054

Is there a reason why we don't create a python environment (venv) and instead we use the global system python? cc: @LoopedBard3

Did you also update the maestro/darc feeds for these?

There are two darc subscriptions for macios repo:

https://github.com/dotnet/macios (.NET 10.0.1xx SDK) ==> 'https://github.com/dotnet/performance' ('main') - Id: 47f1dd75-a07a-4071-a43a-0a3050de377c - Update Frequency: EveryBuild - Enabled: True - Batchable: False - Excluded Assets: [] - PR Failure Notification tags: - Source-enabled: False - Merge Policies: Standard ignoreChecks = [] - Last Build: 20251215.11 (c60d1ae6ba4fd32ef99ccf94aca56e03c51eab86) https://github.com/dotnet/macios (.NET 9.0.1xx SDK) ==> 'https://github.com/dotnet/performance' ('main') - Id: 764d9e7b-4353-484e-a756-e1d6d03fd0a9 - Update Frequency: EveryBuild - Enabled: True - Batchable: False - Excluded Assets: [] - PR Failure Notification tags: - Source-enabled: False - Merge Policies: Standard ignoreChecks = [] - Last Build: 20251008.10 (4177c9d9590857cfb2617fd7a7ef3d5e1de48ed3)

Should I update 47f1dd75-a07a-4071-a43a-0a3050de377c to be .NET 11 and remove 764d9e7b-4353-484e-a756-e1d6d03fd0a9? I assume it isn't intended to have different subscriptions for the main branch.

Ah, one other update should be made to the .NET 9 versions below these updated ones, adding in the CoherentParentDependency, something like updating the lines to these:

  <Dependency Name="Microsoft.MacCatalyst.Sdk.net9.0_26.0" Version="26.0.9754" CoherentParentDependency="Microsoft.MacCatalyst.Sdk.net10.0_26.1"> <Uri>https://github.com/dotnet/macios</Uri> <Sha>4177c9d9590857cfb2617fd7a7ef3d5e1de48ed3</Sha> </Dependency> <Dependency Name="Microsoft.macOS.Sdk.net9.0_26.0" Version="26.0.9754" CoherentParentDependency="Microsoft.macOS.Sdk.net10.0_26.1"> <Uri>https://github.com/dotnet/macios</Uri> <Sha>4177c9d9590857cfb2617fd7a7ef3d5e1de48ed3</Sha> </Dependency> <Dependency Name="Microsoft.iOS.Sdk.net9.0_26.0" Version="26.0.9754" CoherentParentDependency="Microsoft.iOS.Sdk.net10.0_26.1"> <Uri>https://github.com/dotnet/macios</Uri> <Sha>4177c9d9590857cfb2617fd7a7ef3d5e1de48ed3</Sha> </Dependency> <Dependency Name="Microsoft.tvOS.Sdk.net9.0_26.0" Version="26.0.9754" CoherentParentDependency="Microsoft.tvOS.Sdk.net10.0_26.1"> <Uri>https://github.com/dotnet/macios</Uri> <Sha>4177c9d9590857cfb2617fd7a7ef3d5e1de48ed3</Sha> </Dependency>

With that update, we should be good to remove the 9.0 feed and update the 10.0 feed to 11.

Done.
