@jjonescz this one is now up-to-date and doesn't show the previous issue anymore. But there are new issues:

CSC : error CS1566: Error reading resource 'Microsoft.VisualStudio.IntegrationTestService.vsix' -- 'Could not find a part of the path 'D:\a_work\1\s\src\roslyn\artifacts\VSSetup\Release\Microsoft.VisualStudio.IntegrationTestService.vsix'.' [D:\a_work\1\s\src\roslyn\src\VisualStudio\IntegrationTest\Harness\XUnit\Microsoft.VisualStudio.Extensibility.Testing.Xunit.csproj]

We probably need to condition this test project out when building inside the VMR: DotNetBuildFromVMR=true

The other one is in runtime:

D:\a_work\1\s\src\runtime\eng\AcquireWasiSdk.targets(45,5): error MSB3073: The command "powershell -NonInteractive -command "& D:\a_work\1\s\src\runtime\eng\download-wasi-sdk.ps1 -WasiSdkUrl https://github.com/WebAssembly/wasi-sdk/releases/download/wasi-sdk-25/wasi-sdk-25.0-x86_64-windows.tar.gz -WasiSdkVersion 25.0 -WasiSdkPath D:\a_work\1\s\src\runtime\artifacts\wasi-sdk; Exit $LastExitCode "" exited with code 52. [D:\a_work\1\s\src\runtime\src\mono\mono.proj]

Is that the powershell policy change thing that people mentioned in chat?

We probably need to condition this test project out when building inside the VMR: DotNetBuildFromVMR=true

That needs cherry pick of the last commit from #3921

src/templating/src/Microsoft.TemplateEngine.Utils/DictionaryExtensions.cs(88,34): error IDE0370: Suppression is unnecessary (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/style-rules/ide0370)

@dotnet/roslyn-ide / @dotnet/roslyn-infrastructure do you know why this diagnostic starts appearing all of a sudden, was there some fix?

I'm also not sure why it doesn't appear in the release/10.0.2xx branch. Maybe it's some .NET 10 vs 11 difference (something with analysis level)...?

Looks like you have a race in roslyn that you might want to look into. Will probably go away after a retry.

@jjonescz looks like this is from dotnet/roslyn#80794 and this is failing in the SB stage2 leg which uses the just built compiler as the toolset.

@jjonescz you are right, my fixes don't work in multi-targeting projects due to different public API annotations in the BCL. Would you mind taking this one over? Feel free to revert my commits.
