Here is what I do. I put a breakpoint at

 [DataObjectMethod(DataObjectMethodType.Delete, false)]
        static public void Delete(string UserName, string original_UserName)
        {
            string userNameForDelete = String.IsNullOrEmpty(UserName) ? original_UserName : UserName;
            Membership.DeleteUser(userNameForDelete, true);
        }

when I come to this breakpoint and try to debug (Ctrl+Alt+C to activate Stack) it somehow gives me an error coming from the above AJAX file.

Let me re-try these steps one more time.
