How resolve this "the resource cannot be found" problem and requested url: /userregistercontroller/userregister/

Make sure that you have installed MVC3 in your system.
Make sure that you have added routing rules in routeConfig.cs correctly.

Secondly try to browse like: /Userregister/AddUser

suppose your controller:
public class UserregisterController
{
public void AddUser()
{
}
}
