I'll let someone benefit from my shear stupidity. I have some dependencies to a completely separate application (let's call this App1). The dll's from that App1 are pulled into my new application (App2). Any time I do updates in APP1, I have to create new dll's and copy them into App2. Well. . .I got tired of copying and pasting between 2 different App1 versions, so I simply added a 'NEW_' prefix to the dll's.

Well. . . I'm guessing that the build process scans the /bin folder and when it matches something up incorrectly, it barfs with the same error message as noted above. I deleted my "new_" versions and it built just dandy.
