title: vs2015 ctp6 error at create new project
body: <p>I'm using <a href="https://www.visualstudio.com/en-us/downloads/visual-studio-2015-ctp-vs.aspx" rel="nofollow">Visual Studio 2015 CTP 6</a>.<br>
  When I click <kbd>New Project...</kbd>, I get an error message: </p>
  
  <blockquote>
    <p>"Object reference not set to an instance of an object".</p>
  </blockquote>
  
  <p>Visual Studio does not crash, but the template choice dialog doesn't appear.
  If I reinstall (all vs2015...) the problem is solved, but only for two days or so...</p>
  
  <p>I know this is beta software, but anyway I really enjoy the improvements, I would be happy if anybody has any idea why this is happening or a shorter time resolution than the overall installation.</p>
