<p>I created an web application in Visual studio 2010 and copied that code in to my project which is running on its own compiler using a batch file. After I am running this application in IIS 7.5 I am getting this error. I reinstalled OS and tried but no use. When I delete temporary files in .NET framework folder I am getting an error as "Source not found"</p>
