Thank you for your response.  What I did when Switched to Qt Creator and 
MinGW is that I deleted all generated files and any build output.  So in 
theory there should be nothing left form the VS builds right?  I also 
made sure that I was pointing the the correct Qt build, because i 
suppose i have to use the MinGW built qt.  I still don't get a working 
plugin.

I may try to make a quick test app from scratch in Qt Creator and see 
what happens.
