Answers (This worked for me:)

1. Shut down VS.NET
2. Browse to the project in Windows Explorer   
3. Delete the /obj/ folder.
4. Delete the project outputs (.dll and .pdb) from /bin (not sure if this step is necessary)
5. Can't hurt but might help: delete the project outputs from any other project /bin folders in the solution that is having issues (wasn't necessary for me)
6. Restart VS.NET
7. Rebuild
