omnisharp-vim VS csharp-language-server

You can probably use omnisharp-vim (OmniSharp is the same tech that powers VS Code's C# experience).

https://github.com/OmniSharp/omnisharp-vim

https://github.com/OmniSharp/Omnisharp-vim is a thing, but I don’t know how good it is. I would probably go with VSCode or Rider (and their respective Vim plugins), as they are quite productive for .NET.

With respect to C#, have you looked at the [OmniSharp](https://github.com/OmniSharp/Omnisharp-vim) plugin?

Then use this if you don't want to use VS Code.

There's a language server for vim (and neovim): https://github.com/OmniSharp/Omnisharp-vim

Are you using omnisharp-vim? It works well in my neovim setup and configuring it was pretty straightforward!

I'm not sure if you are using the omnisharp command as an example or something you'd like to be able to do, but if it's the latter check out omnisharp-vim! I use it as my LSP for C# development and it integrates most all of omnisharp's functionality with neovim very well.

So OmnySharp has a help document „integrated“. Just type :h omnisharp-vim into vim and you should see it. Alternatively you can go to https://github.com/OmniSharp/omnisharp-vim/blob/master/doc/omnisharp-vim.txt and look at it there. In general: if a plug-in provides documentation, it’s probably stored under /doc/.txt As the c# langauage server is not a vim plug-in, it does not follow this standard. So I unfortunately can’t help with that.

The recommended approach used to be coc-omnisharp, but it has been discontinued in favor of chsarp-ls. I have installed csharp-ls with dotnet tool install --global csharp-ls, and the executable is on ~/.dotnet/tools. The following is on my coc settings:

I switched to https://github.com/razzmatazz/csharp-language-server which doesn't have as many features.

Apropos lsp, these two might be interesting, if you haven't yet given up on C#. Again, that should work on many editors, including the evil one at hand. Note how both explicitly name vim, emacs and vscode in their documentation.

It using lsp protol.i tried the new version of omnisharp with lsp but its really bad, 2 client extension if you don't want to use omnisharp https://github.com/statiolake/vscode-csharp-ls And https://github.com/vytautassurvila/vscode-csharp-ls And last, server lsp https://github.com/razzmatazz/csharp-language-server

lol quite specific. do you know https://github.com/razzmatazz/csharp-language-server ?

There's Saulius's lsp too too, altogh I haven't tried it yet.

You could also set the semantic tokens capability to nil. Another alternative to omnisharp is csharp-language-server which has recently added support for semantic tokens.

I ended up using csharp_ls, https://github.com/razzmatazz/csharp-language-server/issues/34 posted what I found here. Once I got things pointing to the right mono dll it started working great.

Sadly, OmniSharp (the LSP for vscode and nvim) isn't all that great. The performance is incredibly bad, easily orders of magnitude worse than VS and Rider.

There is this alternative LSP, which I plan to try out still: https://github.com/razzmatazz/csharp-language-server

I don't know about your case, but wanted to add a comment. I had some problems recently with omnisharp, and someone recommended me to try https://github.com/razzmatazz/csharp-language-server instead of omnisharp, I switched and so far with no issues.
