Omnsharp doesn't works in WSL

[Johan-Palacios]

I installed Omnisharp vim in my Ubuntu in WSL, and this plugin doesn't work, I tried to reinstall the plugin and activate other options, but it not works, can you give me a solution?

WSL2? It currently doesn't look like OmniSharp-vim and talk to the OmniSharp-roslyn server in WSL2, see issue #706: Omnisharp-vim not doing anything on WSL2

[nickspoons]

You've given no details of what the problem is. I don't know if you are trying to use a Windows server or just code Linux dotnet projects in WSL. Please share your config and log and give enough information to understand your issue.

OK, so you're working on raw .cs files (no .csproj or .sln) on the Windows filesystem, from WSL.

Is this WSL1 or WSL2? You can check by running wsl.exe --list -v

[Johan-Palacios]

This is the return :
NAME STATE VERSION
Ubuntu Running 1

It's WSL 1

[nickspoons]

And what is not working? If you add this to your .cs file and put the cursor on the 2nd line, does :OmniSharpGotoDefinition move the cursor to the first line?

void CallMe() {
    System.Console.WriteLine("Called");
}
CallMe();

[Johan-Palacios]

The autosuggestions isn't works ._. but the other funcions works well

And the OmniSharpGotoDefinition works well

[nickspoons]

OmniSharp-vim doesn't provide autocompletion. It provides completions which can be triggered manually with <C-x><C-o>, or you can use an autocompletion plugin to trigger them as you type.
