Thank you PongGod!! I am not able to comment on your answer but I wanted to post anyway since I had the exact same issue while running an instance of Orchard. In my case, everything had been running great until I found a bunch of old project files located in:

%USERPROFILE%\My Documents\My Web Sites\

And started deleting them for no apparent reason. I then tried to start up Orchard from Visual Studio in debug mode and received the error message above. After applying the same fix to my applicationhost.config file, everything is working fine now.

In my case, I am assuming that the directories got mixed up because I had initially ran the default Orchard files from Visual Studio and from Web Matrix. Then later on, I downloaded the full source files and began running the files from a completely different directory. Thanks again.
