title: Intellisense no longer works
body: <p>I've been using Visual Studio Code with unity for around 2 months now without problems, but since last week I suddenly get no more Intellisense (no code completion for C# or Unity). I don't recall changing anything and I have no idea why it suddenly stopped working.  </p>
  
  <p>I was using Unity 5.4 with <a href="https://github.com/dotBunny/VSCode/" rel="nofollow noreferrer">this recommended plugin</a> to enable VSCode integration when Intellisense stopped working.   </p>
  
  <p>I've already reinstalled VSCode and updated Unity to version 5.5. Unity 5.5 has built in support for VSCode, so I've removed the editor plugin from my project. I can indeed open Unity scripts in VSCode without the plugin now, but I'm still not getting any code completion.   </p>
  
  <p>I saw there was an update for the C# VSCode extension today, but updating that didn't help either. I've attached a screenshot of the log during this update: </p>

  <p>As you can see there's no flame icon and the code completion is missing. The Omnisharp log is either empty or completely missing (not sure why this behaviour is not always the same). </p>
  
  <p>Does anyone have any idea what I can do to fix this? Thanks.</p>
