Migration from Visual Studio 2008 to 2013 : Website is not running (throwing access denied error)

Migration from Visual Studio 2008 to 2013

Without any code changes I successfully migrated from VS 2008 to 2013 but when running website from VS 2013 I got below error.

Server Error in '/' Application.
Access is denied.

Change the below settings to make everything works.

1. Goto Project properties (F4)
2. Update AnonymousAuthentication to Disabled
3. Update WindowsAuthentication to Enabled

Another way also u can change the settings
Go to "\My Documents\IISExpress\config\applicationhost.config" folder and update anonymousAuthentication to be false and the windowsAuthentication mode to true.
