Determine assembly versions used by/referenced in another assembly

Question

Is there a tool that can list the exact versions and public keys of all assemblies referenced in another assembly?

I inherited a solution that contains a medium number of projects each referencing various external assemblies. The test project cannot execute because libraries referenced by it have references to different versions of the same assembly. I need to track down who's referencing what so I can fix it.

Some of the references are in the projects, some are in the external libraries.

Update: To clarify, I'd prefer a command line tool so I can automate this hunt.

Answer 1

Reflector can show you this; click on the assemblies under the References folder, and you can check the version number below the list:

Answer 2

You can use the Fusion Log Viewer to determine exactly what is failing to load as opposed to manually walking dependencies in Reflector or ILDasm.
