The Mailowl Scrolls

Here’s a list of abstract methods I have to implement on my custom MembershipProvider which aren’t applicable since I’m planning on using CardSpace as my login mechanism which doesn’t have any passwords:

bool ChangePassword(string username, string oldPassword, string newPassword)

bool ChangePasswordQuestionAndAnswer(string username, string password, string newPasswordQuestion, string newPasswordAnswer)

bool EnablePasswordReset

bool EnablePasswordRetrieval

string GetPassword(string username, string answer)

int MaxInvalidPasswordAttempts

int MinRequiredNonAlphanumericCharacters

int MinRequiredPasswordLength

int PasswordAttemptWindow

MembershipPasswordFormat PasswordFormat

string PasswordStrengthRegularExpression

bool RequiresQuestionAndAnswer

string ResetPassword(string username, string answer)

Not that it’s a train-smash to put some default values in or throw a NotImplementedException but I wonder if we’ll see a change in the MembershipProvider abstract class for feature version of ASP.NET.

On a side note, although .NET has a NotImplementedException (since .NET 1.1) why does Visual Studio throw a general exception with the message “The method or operation is not implemented.”?
