title: Use an External ResourceDictionary in a WindowsPhone 7 app
body: <p>I am trying to create an ResourceFile Called DataTemplate.xaml in an external dll and use that in a WP7 page.  When I do the following in the header of my Page I get an error</p>
  
  <p><code>
  &lt;ResourceDictionary Source="pack://application:,,,/WP7SharedClassLibrary;component/DataTemplate.xaml" /&gt;
  </code></p>
  
  <p>The error is
  "Current project does not support 'application' as the authority component of the pack URI."</p>
  
  <p>Has anyone else come across this and solved this?</p>
