OmniSharp errors during linting

System Specs

OS

Linux Distro: Void Linux https://voidlinux.org/ Kernel Version: 5.18.19_1 Csharp netcore 6.0 (dotnet)

nvim -v

NVIM v0.7.2 Build type: Release LuaJIT 2.1.0-beta3 Compiled by void-buildslave@a-fsn-de5.18.19_1

Issue

Please see if the error can be replicated with the following Csharp code:

5.18.19_1public abstract class Base_Class
<
    TThis_Base
>
where TThis_Base : Base_Class<TThis_Base>
{
}

public class Expand_Base
<
    TThis_Expansion,
    TChild
> :
Base_Class
<
    TThis_Expansion
>
where TThis_Expansion :
    Expand_Base<TThis_Expansion, TChild>
where TChild :
    Expand_Base<TThis_Expansion, TChild>
    .Child<TThis_Expansion, TChild>
{
    public class Child<TParent, TThis_Child>
    where TParent : Expand_Base<TThis_Expansion, TChild>
    where TThis_Child : Child<TParent, TThis_Child>
    {
    }
}

Rewriting, under Expand_Base:

where TChild :
    Expand_Base<TThis_Expansion, TChild>
    .Child<TThis_Expansion, TChild>

Will result into numerous amounts of errors. Code however, compiles with dotnet.

Are you using the net6 build of the server, or the default mono version? If not using the net6 version please try it:

Add this to your .vimrc:

let g:OmniSharp_server_use_net6 = 1

Then re-install the server with :OmniSharpInstall

If you still have problems, then attach a log (:OmniSharpOpenLog)

I had a git-clone and compiled version of OmniSharp with a OmniSharp_server_path in my .vimrc (specifically, init.vim.) Removing the OmniSharp_server_path and using let g:OmniSharp_server_use_net6 = 1 followed up with an :OmniSharpInstall still results in the same behavior with the bug-replication code.

Here is the :OmniSharpOpenLog

Ok that log looks fine, and OmniSharp-vim appears to be working correctly. If you're getting errors that you think are incorrect, they are coming from the server so you'll need to open an issue with OmniSharp-roslyn

Thanks, I made a new issue over there https://github.com/OmniSharp/omnisharp-roslyn/issues/2448
