False positive errors when working with Monogame

Hi,

Ok well you can see from those [warn] and [fail] messages that the server isn't loading properly, presumably you can't run it from wsl2? Is it a .NET Framework project?

I tried to create an OpenGL MonoGame project under my WSL home folder to try to address the two issues pointed by the logs (the project not being written on Windows and the path lenght). Still having the same issues despite the logs seems that everything is fine).

[ebiscaia]

Well seems like the problem is when I try to run monogame for Windows as I am having no issues with the openGL version. Just tried them side-by-side.

I don't think there's an error here, just a bit of confusion about where the project has been built, and where omnisharp-roslyn is running.

• When the project has been built in Windows, you'll need to be running a Windows build of omnisharp-roslyn. This can be done by using let g:OmniSharp_translate_cygwin_wsl = 1 in your .vimrc, although there are issues with how omnisharp-roslyn communicates with Windows from WSL2, see Omnisharp-vim not doing anything on WSL2 #706
• When the project has been build in linux (locally inside WSL) then you'll need to be running a linux build of omnisharp-roslyn, which is what you've done here.
