The controller for path '...' was not found or does not implement IController

I am trying to publish my MVC2 app to a IIS7. Running locally works fine, but once I publish, I'm getting an error "The controller for path '/mycontroller' was not found or does not implement IController"

Is there some magic t开发者_Python百科hat I missed on published?

It turns out that IIS's folders were set up incorrectly. The tip for me was that there was a prefix in the path displayed in there error. (It really wasn't just /mycontroller')
