Remarks
Takes, as input, an email address and returns the first user name from the data source where the email address matches the supplied email parameter value.
If no user name is found with a matching email address, null is returned.
If multiple user names are found that match a particular email address, only the first user name found should be returned. You can implement a custom mechanism for ensuring a unique email address for each user name such as the RequiresUniqueEmail property supported by the SqlMembershipProvider provider.
