Microsoft.CodeAnalysis.ResxSourceGenerator generating invalid C# for .resx in Shared Project

Microsoft.CodeAnalysis.ResxSourceGenerator

Problem

Corruption seems to creep in that produces many compile errors. See the screenshot that reveals the generated code and the corruption inside it (notice the namespace declaration):

Restarting VS did not solve the corruption problem. 😱
The corruption problem only reproduces (so far) for the SharedStrings.resx file which is in a Shared Project that is consumed by two csproj's in the solution. The namespace corruption includes what looks like the path to the directory containing the resx file.

This is with v3.3.5-beta1.23330.2 of the source generator, and VS 17.7.1.

Shared Projects have long been poor fits for files that generate designer files as code-behinds because each head wants to drive it individually. I have high hopes that the resx source generator can make resx files work much better in this project type.

[AArnott]

It looks like the namespace might be derived from the path to the resx file. In the case of shared projects, that path is a full path.

@AArnott does this issue only occur inside VS (design time), or are you seeing similar behavior for actual builds? If it's the latter, it may have been fixed by #6970.

[AArnott]

Still repros with 3.11.0-beta1.23472.1, which came out two days ago.

@AArnott The fix I referenced first shipped in 3.11.0-beta1.23503.1. You might need to update your NuGet feeds (publication was moved to dotnet9)

[AArnott]

I was looking at nuget.org, actually. But I'll try the version you suggested.

[AArnott]

It still fails with 3.11.0-beta1.23511.1.

BTW, the items created by VS when I moved the .resx files to the Shared Project are:

  <ItemGroup>
    <EmbeddedResource Include="$(MSBuildThisFileDirectory)SharedStrings.es.resx">
      <EmitFormatMethods>true</EmitFormatMethods>
      <DependentUpon>$([System.IO.Path]::ChangeExtension($([System.IO.Path]::GetFileNameWithoutExtension(%(Identity))), '.resx'))</DependentUpon>
    </EmbeddedResource>
    <EmbeddedResource Include="$(MSBuildThisFileDirectory)SharedStrings.resx">
      <EmitFormatMethods>true</EmitFormatMethods>
    </EmbeddedResource>
  </ItemGroup>
