.NET Framework (current version)
Gets a reference to the default membership provider for the application.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System.Web.Security.MembershipProviderThe default membership provider for the application exposed using the MembershipProvider abstract base class.
The Provider property enables you to reference the default membership provider for an application directly. This is commonly used to access custom members of the membership provider that are not part of the MembershipProvider abstract base class.
The following code example accesses the default SqlMembershipProvider enabled for the application using the Provider property in order to determine the value of the custom RequiresUniqueEmail property.
