Mono build to load MSBuild#944

opened on Mar 11, 2023

Using a patched homebrew installation of omnisharp (OmniSharp/homebrew-omnisharp-roslyn#18), I am not able to start the language server. Note I am using omnisharp via mono (as opposed to the .NET Core implementation) at the recommendation of the above homebrew tap's README:

$ cat `which omnisharp`
#!/usr/bin/env sh
mono /opt/homebrew/Cellar/omnisharp-mono/1.35.3/libexec/OmniSharp.exe $@

I strongly suspect OmniSharp/omnisharp-roslyn#2339 is related and will be looking at using the .NET Core implementation after submitting this issue.

I cannot verify the specific version of omnisharp I'm using as omnisharp --version panics (including that panic here to hopefully add information that can be sued to draw a more specific pattern than 'MSBuild can't load'):

The specific LSP client I'm using is eglot and I receive this output in the buffer opened by M-x eglot-events-buffer (with <clipped-project-path> replacing the real project path/name):
