What could be the issue, and sorry for the messy .vimrc, im pretty new to using vim as an IDE. If a class is in the same file that im currently editing it will work fine but, it wont when im in a different file.

Hi,

You haven't said anything about what version of .NET you are using. Is it safe to assume you are not using .NET Framework?

You probably need to use the net6 version of the OmniSharp-roslyn server. Add this to your .vimrc:

let g:OmniSharp_server_use_net6 = 1

Then re-install the server with :OmniSharpInstall

If you still have any issues, check the output of the log, :OmniSharpOpenLog

I am using .net 8 sorry for not mentioning

[MaciejCwalina]

Closed the issue by mistake, sorry

[nickspoons]

I am using .net 8 sorry for not mentioning

That's fine, the let g:OmniSharp_server_use_net6 = 1 setting is to differentiate from the old .NET Framework builds of OmniSharp-roslyn. You want to use let g:OmniSharp_server_use_net6 = 1 as described in my previous comment.

Yes i have tried that, and it indeed works, thanks !
