Failed to handle request textDocument/codeAction, Unable to load Microsoft.Extensions.Logging.Generators

[jensenjw]

When using code actions on types that hasn't been imported OmniSharp fails to suggest any options.
Code actions like adding param to constructor works. There seems to be something with imports.

This has worked without problems in the past, up until yesterday. I Updated packages in plugins imported through Lazy and Mason.
I have testet Omnisharp v1.39.12 and v1.39.11, both run into the same problem.

Error message in lsp.log

I have tried reinstalling everything without luck.

I'm not sure of the root cause but I have a workaround, at least in my case.

I have a library that has has a ProjectReference and a PackageReference. The ProjectReference has dependency that pulls in Microsoft.Extensions.Logging 8.0.0 while the PackageReference depends on Microsoft.Extensions.Logging.Abstractions 8.0.1.

Explicitly adding a dependency on Microsoft.Extensions.Logging.Abstractions 8.0.1 in the ProjectReference seems to fix this problem.
