CompilerServer: server failed - server rejected the request due to analyzer/generator issues

Actual behavior

Tried to add cswin32 to a net6 project. Works fine with 0.1.422-beta but fails with 0.1.506-beta with the following error when attempting to build (can provide binlog if it's helpful):

Expected behavior

Expect the analyzer to load

Repro steps

1. NativeMethods.txt content:

CreateFile

2. NativeMethods.json content (if present):

3. Any of your own code that should be shared?

Context

• CsWin32 version: 0.1.506-beta
• Win32Metadata version (if explicitly set by project):
• Target Framework: [e.g. netstandard2.0] net6.0
• LangVersion (if explicitly set by project): [e.g. 9]

FYI this isn't reproing this morning. Not sure if it's a transient thing, but I'll keep it open in case someone knows where this error comes from

[AArnott]

This doesn't repro for me either. If it happens again, I suggest you open a bug against dotnet/roslyn.

[jnm2]

This is reproing for a coworker.

@jnm2 can you open a bug against dotnet/roslyn and link back to it from here?

[jnm2]

I suppose, though was using Rider at the time and I'm not sure if this is a Roslyn message or not.

[AArnott]

ah, good point. I've never seen the message myself. Maybe it is Rider specific. In which case, file a bug against them?

There's nothing CsWin32 can do. Well, not quite true. #843 and #846 seem relevant. Can you try the latest CI build to see if it resolves your issue?
