Unable to see all completions or diagnostics in LSP mode

[patilarpith]

Running omnisharp-roslyn running in -lsp mode and the project is initialised with csproj file targetting netcoreapp3 framework.

I see no errors in initialisation and the project is loaded successfully.

1. On textDocument/completion request, I only see responses of global keywords. No completion for inbuilt classes or Namespaces.

For eg: Triggering textDocument/completion for Console. results in zero suggestions.

2. I don't see any diagnostics information pushed from the server either.

Versions:
dotnet sdk: 3.1.100
omnisharp roslyn: 1.34.9 (latest)
Language client: monaco-languageclient
monaco-editor:
Mono: Shipped with omnisharp-roslyn

Here is a minimum setup of the project: https://github.com/patilarpith/monaco-languageclient-omnisharp-lsp

We are encountering the same issue in:

• C# completion - candidates don't match the context emacs-lsp/lsp-mode#1108

The think I is, if I move the cursor in my tests a little bit (up), I can sometimes manage to get the proper list of completions so it seems that the server and the editor contents get out of sync for some reason.

There are other (seemingly) related issues already registered, where the editor is out of sync with the server:

• [LSP] initialized seems to be sent too eagerly #1245
• LSP sometimes sends initialized too early and ignore some following events #1445
• Early request to /highlight endpoint throws NullReferenceException #1521
• Monitoring project state (wait until fully loaded etc.) #1580

I believe this has been fixed by:

• Update OmniSharp.Extensions.LanguageServer to "0.14.2" to fix synchronisation Update OmniSharp.Extensions.LanguageServer to "0.14.2" to fix synchronisation #1791

(not released yet, though)
