title: Visual Studio WinJS Phone project can't add .dll reference?
body: <p>Sorry if the question is generic, I am trying to add external references to my project. e.g. the player framework for WinJS. However, whenever I try to add a reference the references are filtered. Only *.winmd files are shown.</p>
  
  <p>Every online explanation I find shows that the reference manager shows both .dll and .winmd files (e.g. <a href="https://playerframework.codeplex.com/wikipage?title=Getting%20Started%3a%20WP8%20Smooth%20Streaming%20Player&amp;referringTitle=Windows%20Phone%208%20Player%20Documentation" rel="nofollow">https://playerframework.codeplex.com/wikipage?title=Getting%20Started%3a%20WP8%20Smooth%20Streaming%20Player&amp;referringTitle=Windows%20Phone%208%20Player%20Documentation</a>).</p>
  
  <p>However, in both my VS2012 and VS2013Express installation, the reference manager filters only *.winmd files.</p>
  
  <p>Am I missing something?</p>
