title: Errors with installing Prism in visual studio
body: <p>I am attempting to use the Microsoft.Practices.Prism library in a universal windows phone/windows 8.1 app in Visual studio 2013. It was working great for the first day. Today when I logged in my build would fail because it claimed it did not have a reference to Microsoft.Practices, however intellisense would pick up both Microsoft.Practices and Microsoft.Practices.Prism. So I uninstalled Prism using nuget package manager, then reinstalled it. Now I am getting this error.</p>
  
  <p>I have seen posts claiming that updating nuget solved this issue but I have the most recent version (I uninstalled nuget and reinstalled)</p>

  <p>Edit: Just for clarification <a href="http://compositewpf.codeplex.com/releases/view/117297" rel="nofollow noreferrer">prism</a> does support 4.5 so this error does not really make much sense</p>
