destination knowledge coming null

Question

created the proxy for remote provider hosted on wcf dynamically :

                         

  WSHttpBinding binding = new WSHttpBinding();


            binding.ReaderQuotas.MaxArrayLength = int.MaxValue;
            binding.Security.Mode = SecurityMode.None;
            binding.ReceiveTimeout = binding.OpenTimeout = binding.CloseTimeout = binding.SendTimeout = new TimeSpan(0, 20, 60);
            binding.MaxReceivedMessageSize = int.MaxValue;


            string url = @"http://10.100.5.170/syncService.svc?wsdl";
            ChannelFactory<ISqlSyncContract> factory = new ChannelFactory<ISqlSyncContract>(binding, new EndpointAddress(url));
            //factory.Credentials.Windows.ClientCredential.UserName = "TCDEV-WEB1\\sai";
            //factory.Credentials.Windows.ClientCredential.Password = "xos2012dec";

           base.proxy = factory.CreateChannel();



            //factory.Credentials.Windows.ClientCredential.UserName = "TCDEV-WEB1\\sai";
            //factory.Credentials.Windows.ClientCredential.Password = "xos2012dec";

           this.dbProxy = base.proxy as ISqlSyncContract;

When doing like this:SyncBatchParameters wrapper = proxy.GetKnowledge(); the destinationknowledge coming null and directly call is going to endsession and throwing object reference not set to instance of an obejct

I suggest you enable Sync Fx tracing or WCF tracing so you can have a look if there's any exception being raised.
