Microsoft.Practices.Unity.ResolutionFailedException

Question

After installing my WPF application, and I try to start the application, it crashes and writes the error below in the event viewer. Does anyone have any ideas?

I know this thread is pretty old, but I just wanted to say that I just had the same exception, and the solution was almost the same too.

Event Viewer had the same result as Joe's. I managed to catch the exception in VS and it showed me "ResolutionFailedException when setting value for the Views.MainWindow property".

However, the real problem was that the entity infrastructure was trying to create a SqlCE database in a directory that did not exist. Pretty simple, but the exception was so strange, although I would share my findings.
