How do I call WCF windows authentication from WPF

BasicHttpBinding Funct_LocalBinding = new BasicHttpBinding();
                  EndpointAddress Funct_LocalEndpoint = new EndpointAddress("http://172.16.50.149:1546/BTA_Service.svc");
                  Funct_LocalBinding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
                  Funct_LocalBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
                  Funct_LocalBinding.Security.Transport.ProxyCredentialType=HttpProxyCredentialType.None;
                  Funct_LocalBinding.Security.Transport.Realm="";
                  Funct_LocalBinding.Security.Message.ClientCredentialType=BasicHttpMessageCredentialType.UserName;
                  Funct_LocalBinding.Security.Message.AlgorithmSuite=SecurityAlgorithmSuite.Default;
                  BTA_ServiceClient serverObject = new BTA_ServiceClient(Funct_LocalBinding, Funct_LocalEndpoint);
                  serverObject.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
                  serverObject.ClientCredentials.Windows.AllowNtlm = true;
                  serverObject.ClientCredentials.UseIdentityConfiguration = true;
                  serverObject.ClientCredentials.Windows.AllowedImpersonationLevel =System.Security.Principal.TokenImpersonationLevel.Impersonation;
                  var str = serverObject.FlightCode_Validation(new PNRModel()
                  {
                      Flight_Code = "AA",
                      RequestId = "4"
                  }
                        );
