I was working on my asp.net (4.0) application, when I had a power fail. When the machine rebooted, I get the error (in the title) when I try and run the app. I can deploy it and run on another server ok. I am trying to use the ASP.Net Development Server.
I can run another (similar) project ok, so it seems to be project related. All code was checked in, so I don't think my code changed. What could be causing this?
