title: Completely uninstall VS Code extensions
body: <p>Since the latest release of VS Code, I get an error whenever I open a C# file (I have installed the csharp language extension, powered by OmniSharp). This is the error I get: </p>

  <p>I tried uninstalling the extension and re-install it, same problem. I uninstalled the application altogether and reinstalled it - but when I do that, my extensions are still installed (for instance Python and reStructuredText were still there). I uninstalled yet again and deleted the <code>%USER%\AppData\Roaming|Local\Code</code> directory. When I reinstalled, the extensions were still there.</p>
  
  <p>How do I completely remove the installed extensions? I'd like to be sure I'm starting from scratch before opening a bug for the OmniSharp extension crash.</p>
