Remarks

Note

ASP.NET membership providers have been superseded by ASP.NET Identity. We strongly recommend updating apps to use the ASP.NET Identity platform instead of the membership providers.

ASP.NET membership is designed to enable you to easily use a number of different membership providers for your ASP.NET applications. You can use the supplied membership providers that are included with .NET Framework, or you can implement your own provider.

Note

If you are not familiar with the membership features of ASP.NET, see Introduction to Membership before continuing. For a list of other topics related to membership, see Managing Users by Using Membership.

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.

The MembershipProvider abstract class inherits from the ProviderBase abstract class. MembershipProvider implementations must also implement the required members of ProviderBase.

Constructors

Initializes a new instance of the MembershipProvider class.
