Unable to start debugging on the web server. Only for ASP NET Debbuger

[ecemdicle]

I am using vs2012 .net 4.5Unable to start debugging on the web server. The web server is not configured correctly.I have been trying to solve this issue for weeks and I cannot find the solutionThis I have tried:[*]Checking which configuration on project properties was causing the problem: I found out that this happens when I set ASP .NET Debugger for debugging.[*]Reinstalled .NET framework[*]Enabled on IIS all authentication type: Anonymous, Forms, Windows Authentication and ASP NET personificationThis happened since I changed my application to run under IIS. I was using VS Development Web server..Could you please gimme some advice on that?Thanks
