The Membership class membership provider specified in the MembershipProvider property can restrict the e-mail addresses that it will accept. The property is displayed when the e-mail address entered by the user does not meet the requirements for the e-mail address set by the membership provider. The actual requirements for the e-mail address are determined by the membership provider, and might be different for different providers.
The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see LocalizableAttribute and ASP.NET Globalization and Localization.
