Implementing your own Membership Provider

Published on Wednesday, September 8, 2010

ASP.NET has already provided membership providers that are included with the .NET Framework. You can use them directly for any web sites without spending your more design. However, you must feel the supplied membership providers are not convenient for your projects. Microsoft MSDN site also gave the reasons why you need to implement your own Membership provider:

There are two common 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 sources.
  • 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._
