Using ASP.NET Membership in Silverlight

If you're used to working with Membership in ASP.NET, you'll eventually find yourself wanting to use that information in your Silverlight client. It's not immediately obvious how to do this so I've put together a sample DomainService that makes Membership available using standard RIA Services patterns.

@@    [EnableClientAccess(RequiresSecureEndpoint = false /* This should be set to true before the application is deployed */)]
    public class MembershipService : DomainServiceBase
    {
        [RequiresRole("Administrator")]
        public IEnumerable<MembershipServiceUser> GetUsers()
        {
            return Membership.GetAllUsers().Cast<MembershipUser>().Select(u => new MembershipServiceUser(u));
        }

        [RequiresRole("Administrator")]
        public IEnumerable<MembershipServiceUser> GetUsersByEmail(string email)
        {
            return Membership.FindUsersByEmail(email).Cast<MembershipUser>().Select(u => new MembershipServiceUser(u));
        }

        [RequiresRole("Administrator")]
        public IEnumerable<MembershipServiceUser> GetUsersByName(string userName)
        {
            return Membership.FindUsersByName(userName).Cast<MembershipUser>().Select(u => new MembershipServiceUser(u));
        }

        [Invoke(HasSideEffects = true)]
        public void CreateUser(MembershipServiceUser user, string password)
        {
            Membership.CreateUser(user.UserName, password, user.Email);
        }

        [RequiresRole("Administrator")]
        public void DeleteUser(MembershipServiceUser user)

            Membership.DeleteUser(user.UserName);
        }

        public void UpdateUser(MembershipServiceUser user)
        {
            Membership.UpdateUser(user.ToMembershipUser());
        }

        public void ChangePassword(MembershipServiceUser user, string oldPassword, string newPassword)
        {
            user.ToMembershipUser().ChangePassword(oldPassword, newPassword);
