I need to reproduce it here just in case it is lost == >

Profile.UserName is a readonly field. So, how do you change a user’s name? Many use email address as user name (like us, Pageflakes) and we want to allow users to change their email address which in turn changes their user name. So, how do you do it?

It looks like there’s no easy way to do it. You have to do the following:

1. Create a new user using the new email address 
2. Get the password of the old account and set it to the new account. If you can’t get the old password via Membership provider, then ask user.
3. Create a new profile for the new user account
4. Copy all the properties from the old profile to the new profile object.
5. Log out user from old account
6. Auto sign in to the new account so that user does not notice what an incredible thing just happened.

Here’s how I do it:

if (Profile.UserName != newUserName)
{
    // Changing email address of user. Delete current user account and create
    // a new one using the new email address but the same password
    if (null != Membership.GetUser(newUserName))
        throw new ApplicationException(“There’s another user with the same email. Please enter a different email.”);  

    MembershipUser newUser = Membership.CreateUser(newUserName, currentPassword);  

    // Create profile for the new user and copy all values from current profile
    // to new profile
    ProfileCommon newProfile = ProfileCommon.Create(newUserName, true) as ProfileCommon;  

    newProfile.IsInvited = Profile.IsInvited;
    newProfile.IsRealUser = Profile.IsRealUser;
    newProfile.Name = newUserName;  

    newProfile.Save();  

    if (Membership.ValidateUser(newUserName, currentPassword))
    {
        FormsAuthentication.SignOut();
        Session.Abandon();  

        // Delete the old profile and user
        ProfileManager.DeleteProfile(Profile.UserName);
        Membership.DeleteUser(user.UserName);  

        //FormsAuthentication.SetAuthCookie(newUserName, true);
        FormsAuthentication.RedirectFromLoginPage(newUserName, true);
    }
}

Starting this blog again. Had to delete earlier posts as I was not able to maintain the site for a long time.
