charp-ls cannot work properly with coc.nvim

[kalium222]

Hello guys, I am trying csharp-ls for both c# project and unity project with vim and coc.nvim. I met these problems

• csharp-ls cannot recognize some newer features in c#, such as file scoped namespace:

  namespace A;  // report error here 

  or simplified new expression:

  List<int> A = new();   // report error here

  but they can be build with dotnet build.

• csharp-ls cannot recognize all the unity things, such as UnityEngine, or Monobehaviour.

But when I was trying csharp-ls in the vscode with the extension, it works well. How to deal with this?

Some possibly useful information.

And configure for coc.nvim:

        "csharp-ls": {
             "command": "~/.dotnet/tools/csharp-ls",
             "filetypes": ["cs"],
             "rootPatterns": ["*.csproj",  "*.sln"]
        }

Thanks very much.

Also, I found that csharp-ls is very slow in completion, for every client. I tried both coc.nvim and the vscode extension, and both have this problem.

slowness problem has been reported in #151, a regression in 0.12.0

Ok, sorry for redundant issue; And I tweaked something in my lsp config, now it work well now.
