ASP.NET Compillation Error BC31007 - Solution

TToday while I am working on the ASP.NET application, I suddenly encountered with below error while trying to debug the application.

I tried couple of actions:

.    ·         Clean and rebuild solution
·         IDE restart
·         Temporary files cleanup
·         System restart
·         Modified Identity in App pool

Finally it got resolved by modifying the Identity to “Local System” in Application Pool

Server Error in '/My App’ Application.
