title: Visual Studio 2015 missing XML comments / documentation
body: <p>Is it me or are the XML comments missing for <code>System.Linq</code> in <em>Visual Studio 2015</em>?
  Because I can still find it on <a href="https://msdn.microsoft.com/en-us/library/system.linq%28v=vs.110%29.aspx">MSDN</a>.
  But when typing, for example, this code:</p>
  
  <pre><code>var list = new List&lt;string&gt;();
  list.Select(
  </code></pre>
  
  <p>IntelliSense doesn't provide the comments/documentation for <em>any</em> class/method/member/extension in the <code>System.Linq</code> namespace:

  <p>Here is a preview when hitting (<strong>Alt</strong> + )<strong>F12</strong> to <em>go to definition</em> for a random extension method on <code>Enumerable</code>:

  I think I didn't notice the docs in Visual Studio 2013 either. But I do remember them being there once upon a time, perhaps that was in Visual Studio 2012 or before?</p>
  
  <p><strong>EDIT</strong>: I've forgot to mention that I've Resharper 10 Ultimate installed in Visual Studio 2015. I've also had Resharper 8 and 9 installed in Visual Studio 2013.</p>
