Exception in language server System.IO.FileNotFoundException

[olstakh]

I feel like it's something trivial, but can't put my finger on it

dotnet new console --language "f#" --name dummy
code -r dummy

Output -> F# Language server logs:

Building/running dummy project works fine, but language server seems to be crashing every time

This project has no support for dotnet 7.0 unfortunately. I suggest you check out "ionide". I'm nota working on this anymore and I should really archive the repo. Ionide is in a great state these days and you should definitely just use that. Good luck :)
