title: Merging Visual Studio Windows Store App and Windows Phone App solutions
body: <p>I have created a HTML5 (canvas+js) game 
  for Windows 8.1  using Visual Studio Express 2013 
  and for Windows Phone 8 using Visual Studio Express 2012 with Windows Phone SDK 8. </p>
  
  <p>How can I merge those solutions into one, or create a new one correctly from beginning, so that the two projects would share most image, sound and javascript files. I would like to work with one set of files, since the files are mostly the same, and build for both platforms at the same time.</p>
  
  <p>Is it possible? I am even willing to buy Visual Studio Pro 2013 to get this done.
  Also can it be used in TFS then?</p>
