title: VS2010 Class Diagram - How to show collection associations between two interfaces?
body: <p>I'm generating some class diagrams from existing code to improve the documentation but I've run into a bit of an obstacle. I'd like to show collection associations on the diagram, but for interfaces this just doesn't seem possible.</p>
  
  <p>If the interfaces are in another assembly, the collection type is displayed in its unbounded form (e.g. <code>ReadOnlyObservableCollection</code>1`) and attempting to display collection associations gives the error</p>
  
  <blockquote>
    <p>This is not a valid type name.</p>
  </blockquote>
  
  <p>If the interfaces are in the same assembly, the collection type is displayed in its bounded form (e.g. ReadOnlyObservableCollection`), but attempts to display the associations come out with the error message</p>
  
  <blockquote>
    <p>Cannot show an association because  cannot be found.</p>
  </blockquote>
  
  <p>Any ideas what I'm doing wrong, or is this just a shortcoming of VS class diagrams?</p>
  
  <p>Thanks,
  James</p>
