  • Hi ADefwebserver!

    I have a qeustion. Is there any way to get windows  user in WCF RIA service who is running the app?

    In WCF RIA service I have a web service call and I need to pass a user to the service. Environment.UserName returns  DefaultAppPool inside RIA service.

    Any suggestions?

  • Sorry I don't have any examples and I have not done that. Everything I do is web based using forms authentication. I had to do a lot of Googling to get the Forms authentication user in this article:

    LightSwitch Survey: Handling Complex Business Logic Using WCF RIA Services

            public void UpdateQuestionDetailForUser(QuestionDetailForUser objQuestionDetailForUser)
                // Get the current user
                string strCurrentUserName = System.Web.HttpContext.Current.User.Identity.Name;
                // We are under Forms Authentication so if user is blank then we
                // are debugging and we are TestUser
                if (strCurrentUserName == "")
                    strCurrentUserName = "TestUser";

  • I believe the LS server context exposes the current username... Might have to dig around a bit to see exactly where, but I recall something like this.

  • Here is code!

            public static string CurrentUserName
                    System.Security.Principal.IPrincipal _User;
                    _User = System.Web.HttpContext.Current.User;
                    System.Security.Principal.IIdentity _Identity;
                    _Identity = _User.Identity;
                    string _Value;
                    _Value = _Identity.Name.Substring(_Identity.Name.IndexOf(@"\") + 1);
                    return _Value;
