Visual Studio Code Intellisense stopped to work on C# files

Question

I realized that I can't use ctrl + . shortcut to import other C# classes. This shortcut works just fine for other file types like typescript.

I have uninstalled and installed back again. I also installed old version of VS code too. But nothing worked.

As I shown above, there is no import feature shows up when I do ctrl + .. Those are only the choices I was given. It's fine using without it but it's also annoying to import those files manually typed.

Answer 1

The C# language features in VS Code are provided by a service called OmniSharp .

A couple of things you could try:

A) Restart OmniSharp

1. Open the Command Palette (Ctrl + Shift + P)

2. Type Omnisharp: Restart OmniSharp

   

B) View OmniSharp Logs

1. Open Output Panel (Ctrl + ')

2. Select OmniSharp Log from the dropdown)

   

C) Enable OmniSharp Logging

1. Enabling C# debugger logging in Omnisharp

   "configurations": [
       {
           "...": "...",
           "logging": {
               "engineLogging": true
           }
       },
       { "...": "..." }
   ]
   

Answer 2

Something that solved it in my case was, in Unity, to set the Edit -> Project Settings -> Player -> Other Settings -> Api Compatibility Level to .NET 4.x.

Probably not appropriate in some cases, and indiciative of another issue in my Omnisharp/ VS Code setup, but just in case it helps someone.
