I thought I was going insane; glad to hear someone else is having this issue too.

Error squiggles, info on hover, refactoring, everything is working but the autocomplete. Very strange.

I'm able to reproduce this with even the most minimal example on Windows 10:

  1. Create a new project with the dotnet CLI tool: 
    $ dotnet new console
The template "Console Application" was created successfully.

Processing post-creation actions...
Running 'dotnet restore' on C:\Users\Rishov\Documents\OmnisharpTest\OmnisharpTest.csproj...
  Determining projects to restore...
  Restored C:\Users\Rishov\Documents\OmnisharpTest\OmnisharpTest.csproj (in 44 ms).
Restore succeeded.
  2. Open the project in VS Code.
  3. Click "Yes" when asked "Required assets to build and debug are missing from 'OmnisharpTest'. Add them?"
  4. Open Program.cs in VS Code.
  5. Inside the static void Main(string[] args) method, type Console. and press Ctrl+Space.
  6. Observe: while red squiggly underlines appear to indicate errors, only spelling suggestions appear for autocompletion.
    image
  7. Hover over the WriteLine in Console.WriteLine("Hello World!");.
  8. Observe: hover info appears correctly.

The extension is working enough to provide error squiggles and know what Console.WriteLine is, but it's not working enough to provide autocompletion for anything.

I am very silly and did not realize I had a pending VSCode update. Once I updated to VSCode 1.58.2, completions work again.
