Implement a custom RoleProvider for Role Permission and Security

To implement a custom Role Provider, you will need to provide a concrete implementation of the RoleProvider class to ASP.NET, and plug it into the system through appropriate configuration settings. The first step in implementing the custom provider is to derive a class from the RoleProvider abstract base class. To provide a complete implementation, you will need to provide overrides for all of the methods and properties of the RoleProvider class.
