Fails on Microsoft.CodeAnalysis.CSharp.Features

[SteveSandersonMS]

If you add the following to your project:

<PackageReference Include="Microsoft.CodeAnalysis.CSharp.Features" Version="2.9.0" />

... then the linker fails with the following error:

1>Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'C:\Users\username\.nuget\packages\microsof.codeanalysis.workspaces.common\2.9.0\lib\netstandard1.3\es\Microsoft.CodeAnalysis.Workspaces.resources.dll, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' ---> Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'C:\Users\username\.nuget\packages\microsof.codeanalysis.workspaces.common\2.9.0\lib\netstandard1.3\es\Microsoft.CodeAnalysis.Workspaces.resources.dll, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'

It looks like it incorrectly thinks the embedded resources are a reference to an external assembly, but they aren't.

Could you please provide self-contained repro?

Thanks @marek-safar for suggesting that, because after some investigation, I've tracked it down to an underlying issue that is not what first appeared. It comes down to a bug in MSBuild, so I'll close this issue and report a different one requesting a workaround for the MSBuild bug.
