C# Extension Stopped Working on Linux

See original GitHub issue

Issue Description

C# extension stopped working properly on Linux. I’ve been using this development environment for nearly a year without issues, and today all the sudden it won’t work. I see some errors logged in the Omnisharp console, and I cannot navigate through my project by ctrl+clicking on types as I used to be. This is probably due to some component update, but I don’t know which.

VSCode also shows a pop up time to time with the error: “Some projects have trouble loading. Please review the output for more details.”

@hiranya911 Could you try setting “omnisharp.useGlobalMono”: never. This will run omnisharp on the mono that is packed in the omnisharp bits that we ship.

@JorgeDLG I don’t understand your problem, but I’m glad you found a way to fix it. In my case I added the mono repository and then installed the latest mono-devel via apt update.
