“Cannot start Omnisharp because Mono version >=3.10.0 is required”

Question

I just installed Visual Studio Code and when I started it, it gives me this error. When I try to execute my example application, it gives me TypeLoadExceptions.

Answer 1

I still can't update my mono version using sudo apt-get install mono-devel until I follow the official website.
