title: Cannot add a page to my project
body: <p>One of my projects in Visual Studio is a WPF project. </p>
  
  <p>I have the default files which are created plus 2 classes which I've added and a couple of folders. </p>

  <p>The issue I have is, when I try to add a Window to my View folder, I can't as I don't have the option of Window (or page for that matter). </p>

  <p>As you can see, for some reason and despite my application being created as a WPF project it now thinks it's a WinForms project.</p>
  
  <p>How do I revert/change it from WinForms to a WPF project?</p>

  <p><strong>EDIT</strong><br>
  Please note, I am using Visual Studio 2012 Premium.</p>
  
  <p>If I add a new WPF project, I do get the options of Page/Window etc, so this fault is project specific.</p>
  
  <p>Based upon the comments, this is the screen I get when I click on Add New Item (sorry I can't fit in the entire list)</p>

  <p>And this is the view of the WPF menu</p>
