title: Visual Studio not showing IntelliSense descriptions anymore
body: <p>Since a month ago, my VS doesn't seem to want to display the summary info in tooltips for any system methods or classes when I hover them with my mouse.</p>
  
  <p>I had ReSharper installed and started noticing this problem. I assumed that ReSharper disabled the default method descriptions, so I wasn't thinking much further about it, only considering it a mere annoyance.</p>
  
  <p>After removing ReSharper though, the problem persisted.</p>
  
  <p>VS now only shows descriptions for my own methods which I've added a <code>&lt;summary&gt;</code> tag for and any descriptions from NuGet packages, but not system methods like <code>Where</code>, <code>Encoding.GetString</code>, etc.</p>

  <p>I've tried repairing VS, resetting settings, un-/checking checkboxes in Options > Text Editor > General, but to no avail.</p>
  
  <p>Has anyone had a similar problem?</p>
