Determining where ambiguous reference is coming from

Question

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?

When I right click and pick go to definition I get

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?

I've had this issue occur when old DLLs are left in the bin directory. Either clean the project or go into the directories in windows explorer and manually remove all files, then rebuild.
