    To find out which specific assembly is throwing a fit try using the Fusion Log Viewer.  It's extremely helpful in situations like this.

    http://www.hanselman.com/blog/BackToBasicsUsingFusionLogViewerToDebugObscureLoaderErrors.aspx

    It should be in your visual studio program group.  Just be sure to right click on it --> run as admin the first time so you can adjust the settings.

    Thanks James. I copied all of the DLLs from an empty project and was able to get past the error.
