My web application was working perfectly minutes ago now I get this error when I run it.

How can I solve this issue since its not even part of my project files?

    Apparently something has changed during these minutes. What was that? Commented Feb 7, 2014 at 11:12
  • configuration files don't change by itself...what did you do between "it was working perfectly" and the error? Commented Feb 7, 2014 at 11:14

I probably should have done this before posting the question.

I saved my work then restarted Visual Studio.
