title: Unity Scripts edited in Visual studio don't provide autocomplete
body: <p>When I want to edit C# Unity scripts, they open in Visual Studio. It is supposed to provide auto complete for all Unity related code, but it doesn't work.</p>
  <p>Here you can see the missing functionality:</p>

  <p>As seen, the <a href="https://docs.unity3d.com/ScriptReference/Transform.html" rel="noreferrer"><code>transform</code></a> object does not open the autocomplete menu.</p>
  <blockquote>
  <p>Unity version: 5.5.2f1<br />
  Visual studio 2015<br />
  Visual Studio Tools for Unity is installed</p>
