This issue might be a duplicate of existing issues. Please check:

  • #1808: C# language server (csharp-ls) doesn't work - Reports C# LSP not working despite having dotnet SDK and csharp-ls installed
  • #3008: Get LSP working for dotnet (.cs) - Reports empty diagnostics response when running LSP debug commands with C# files
  • #7503: csharp-ls.exe running is locking files and prevents build - Reports csharp-ls.exe process issues on Windows

Feel free to ignore if none of these address your specific case.

possibly fixed in #6763 due to path mismatching issues in lsp.ts
