If the SimpleMembershipProvider class has been initialized using a call to the WebSecurity.InitializeDatabaseConnection() method, this method is not supported and will throw a NotSupportedException exception. However, if the WebSecurity.InitializeDatabaseConnection() method has not been called, and if you have configured your site to use the standard ASP.NET membership provider, this method is passed through to the standard membership provider. For more information, see the SimpleMembershipProvider class overview.
