c# - WCF over net.tcp with security mode none gives exception -

we streaming data wcf using callbacks. wcf hosted in iis (default settings, added net.tcp protocols).

we trying disable security on wcf, i've set security mode "none", both on client , server, following communicationexception:

the socket connection aborted. caused error processing message or receive timeout being exceeded remote host, or underlying network resource issue. local socket timeout '00:00:59.8439844'.

i've put on tracing on service , traceviewer gives me following exception (system.servicemodel.protocolexception):

stream security required @ http://www.w3.org/2005/08/addressing/anonymous, no security context negotiated. caused remote endpoint missing streamsecuritybindingelement binding.

client program.cs:

using system; using system.servicemodel; using wcfclient.servicereference1;  class program {     static void main() {         callback callback = new callback();         instancecontext context = new instancecontext(callback);         service1client service1client = new service1client(context,                                                             "nettcpbinding_iservice1");           service1client.getdata(0);         console.read();         service1client.stop();     } }  internal class callback : iservice1callback {     public void streamsignaldata(int[] result) {         foreach (int in result) {             console.writeline(datetime.now.tostring("dd.mm.yyyy hh:mm:ss.fff") +                                ": " + i);         }     } }

any ideas might be? of hits on google configuration on client , server should same (i.e. security none), can't seem find error. googling streamsecuritybindingelement came no explenations...

i not replicate problem have same setup , few things noticed:

create namesapace in wcf service1.svc.cs.

callback

make sure handle _callback.streamsignaldata(randomnumbers); when client disconnects. communication exception.
