Test failures now occur with GenerateRuntimeGraphTests, e.g. CanAddArchitectureToExistingGroups ends with System.TypeInitializationException : The type initializer for 'Microsoft.Build.Shared.Debugging.DebugUtils' threw an exception and System.PlatformNotSupportedException : Operation is not supported on this platform..

The logs are available here: Build Build iOSSimulator x64 Release AllSubsets_Mono failed and here Build Build tvOSSimulator x64 Release AllSubsets_Mono failed

cc @ericstj as I think that you introduced those tests

[ericstj]

Those tests require MSBuild assemblies and use a subset of that functionality on the target machine. When they were added they worked on all platforms they were run on with the exception of Browser. We decided at the time it wasn't interesting to execute MSBuild on the browser so we added

runtime/src/libraries/Microsoft.NETCore.Platforms/tests/AssemblyInfo.cs

Line 6 in 794f1af

[assembly: SkipOnPlatform(TestPlatforms.Browser, "MSBuild is not supported on Browser")]

Based on this issue, it looks like either more platforms were added, or existing platforms introduced new unsupported API. It's likely a similar case to Browser here: what do you think @steveisok?

[steveisok]

Yeah, I think we can lump iOS and Android in the same as the browser.
