my web application cominucates with a win app , my problem is i can't register a new user through win app,(the "InitialiseProfile" method raised error so i have to comment it)

i used a code like this :

                                     DotNetNuke.Entities.Users.UserInfo userInfo = new DotNetNuke.Entities.Users.UserInfo();

                //userInfo.Profile.InitialiseProfile(0,true);
                userInfo.AffiliateID = -1;
                userInfo.DisplayName = username;
                userInfo.Email = email;
                userInfo.FirstName = userInfo.Profile.FirstName = "";
                userInfo.LastName = userInfo.Profile.LastName = "";
                userInfo.IsSuperUser = false;
                userInfo.Membership.Approved = true;
                userInfo.Membership.CreatedDate = DateTime.Now;
                userInfo.Membership.Email = email;
                userInfo.Membership.Password = password;
                userInfo.Membership.UpdatePassword = true;
                userInfo.Membership.Username = username;
                userInfo.Username = username;
                userInfo.PortalID = 0;
                userInfo.Profile.PreferredLocale = "fa-IR";
               

                status = DotNetNuke.Entities.Users.UserController.CreateUser(ref userInfo);

it never worked :-(

i supposed it may because of a connection string problem, so i add a web.config to my win app and a proper connectionstring but it still has the same general non specific non detailed exception of  "userController threw exception"

i will appreciate any help. how i can create dnn users outside of web app?

ahhhhhhh, holy mother of jesus christ

i tried to do user registration outside of db by calling CreateUser method of membership but there is same problem : which db to connect where we should look, what we should do?
