Hi

This code works for me:

var userService = ApplicationContext.Current.Services.UserService;

var email = "youremailhere";
var date = DateTime.Now;
var userType = new ProvisioningUserType()
{
    Alias = "admin",
    Name = "Administrators",
    CreateDate = date,
};
var user = userService.GetByEmail(email);
userService.SaveUserType(userType);
if (user == null) {
    // Create a new user
    var newUser = userService.CreateUserWithIdentity(email, email, userType);
    newUser.RawPasswordValue = (Membership.Providers["UsersMembershipProvider"] as UsersMembershipProvider).HashPasswordForStorage("password"); ;
    // Save the new user
    userService.Save(newUser);
}

is working on a reply...
