title: Unable to Use Nuget with MvvmCross - PCL
body: <p>Following the tutorial for mvvmcross here: <a href="http://www.youtube.com/watch?v=_DHDMNB_IeY&amp;list=PLR6WI6W1JdeYSXLbm58jwAKYT7RQR31-W&amp;index=1" rel="nofollow noreferrer">http://www.youtube.com/watch?v=_DHDMNB_IeY&amp;list=PLR6WI6W1JdeYSXLbm58jwAKYT7RQR31-W&amp;index=1</a></p>
  
  <p>I've set up my PCL xml files to include MonoTouch and Mono for Android as instructed here: <a href="http://slodge.blogspot.co.uk/2013/04/my-current-pcl-setup-in-visual-studio.html" rel="nofollow noreferrer">http://slodge.blogspot.co.uk/2013/04/my-current-pcl-setup-in-visual-studio.html</a></p>
  
  <p>If I try to use nuget I get an error that an item with the same key has already been added:

  <p>I can add other project types to the solution and NuGet works fine, it's something specific to PCL projects.  Here is the console output:</p>
