title: Determining where ambiguous reference is coming from
body: <p>I need help determining where 'ambiguous reference' is coming from. When I look at my project, there is no version 3.6.0.1 referenced (directly anyways).
  Is there a tool to see how it finds this version so I can resolve this issue?</p>

  <p>Is there a way to tell how each version is associated with this current project?
  In references, only 3.6.0.0 is referenced. 
  Could this be a VS or resharper6 cache bug?</p>
