Explanation:
When implementing a custom membership provider, you are required to inherit the
MembershipProvider abstract class.
There are two primary reasons for creating a custom membership provider.
You need to store membership information in a data source that is not supported by the
membership providers included with the .NET Framework, such as a FoxPro database, an Oracle
database, or other data source.
You need to manage membership information using a database schema that is different from the
database schema used by the providers that ship with the .NET Framework. A common example of
this would be membership data that already exists in a SQL Server database for a company or Web
site.
