Microsoft.Build.Exceptions.InvalidProjectFileException: The imported project "C:\Users\runneradmin\AppData\Local\Temp\541ofin3.s03\ProjectWithAnalyzers\obj\ProjectWithAnalyzers.csproj..props" was not found. Confirm that the expression in the Import declaration "C:\Users\runneradmin\AppData\Local\Temp\541ofin3.s03\ProjectWithAnalyzers\obj\ProjectWithAnalyzers.csproj..props" is correct, and that the file exists on disk. D:\a\omnisharp-roslyn\omnisharp-roslyn.msbuild\Current\Microsoft.Common.props

is this *.props some new MSBuild feature? I find it hard to comprehend what fails here

System.BadImageFormatException: Could not resolve field token 0x0400110f, due to: Could not load type of field 'Microsoft.Build.Shared.FileSystem.ManagedFileSystem+<>c:<>9__10_0' (1) due to: Could not load file or assembly 'Microsoft.IO.Redist, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. assembly:/Users/runner/work/omnisharp-roslyn/omnisharp-roslyn/bin/Release/OmniSharp.MSBuild.Tests/net472/Microsoft.Build.dll type:<>c member:(null)

Looks like on Unix we need to include Microsoft.IO.Redist in the local msbuild?

this is some dark magic man

I think we need to expedite getting rid of the standalone msbuild feature as we discussed.

I agree. I opened an issue and it should get resolved for 17.2 (dotnet/msbuild#7335), but not shipping is best path forward.
