Known O# LSP issues #5429
Description
When running with the C# extension built from the feature/lsp-engine branch and omnisharp.enableLSPDriver set to "true".
- LSP Logging to the OmniSharp log is duplicating every line (Register the LanguageServerLogger only once OmniSharp/omnisharp-roslyn#2473)
- O# LSP sends across multiple registrations for the same command. One for the C# handlers and a second for the Cake handlers. This causes LSP features to not register. Removing the OmniSharp.Cake.dll from the O# distribution is a workaround. DavidB suggests having O# LSP merge the registrations by combining the document selectors. (Implement LSP CodeAction resolve OmniSharp/omnisharp-roslyn#2467)
- Some features do not consistently trigger (Signature Help, Format Document on Type,).
- Some features seems to double register (Completion, Hover,).
- Need to add support for metadata documents and source generated documents.
- CodeLens handler does not support Run/Debug Test lenses.
- InlayHint handler can't be implemented until csharp-language-server-protocol updates to 3.17 api.
- Diagnostics handler is not implemented.
- Need to implement custom LSP commands for some O# functionality FixAll, Run/Debug Tests in Context.
- Many messages are still being sent to O# using their O# protocol adapter (RequestWorkspaceInformation, etc...). This may not be an issues unless O# wants to remove the adapter and O# protocol support.
