My Python3 server code:

import zmq
context = zmq.Context()
router = context.socket(zmq.ROUTER)
router.bind("tcp://*:1337")

router.send_multipart([b'build_0', b''])

while True:
 pass

My C# client code:

/// <summary>
/// Receive data from server.
/// </summary>
private void RecvFromServer()

 // Init the socket.
 recvFromServerSocket = new DealerSocket();
 recvFromServerSocket.Options.Identity = StringToByteArray("build_0");
 recvFromServerSocket.Connect(NETWORK_PREFIX + serverAddress + PORT_INFIX + recvFromServerPort);

 NetMQMessage frames = new NetMQMessage();

 // When the socket is ready, receive a multipart message.
 recvFromServerSocket.ReceiveReady += (o, s) =>
 
 onBeginListenToServer?.Invoke(ref BenchmarkData.benchmark.began_to_listen_to_server);
 frames = s.Socket.ReceiveMultipartMessage();
 foreach (NetMQFrame frame in frames)
 
 Debug.Log(frame.ConvertToString());
 messagesFromServer.Enqueue(frame.ConvertToString());
 
 frames.Clear();

 onReceivedMessage?.Invoke(ref BenchmarkData.benchmark.received_from_server);
 ;

 // Init the poller.
 recvFromServerPoller = new NetMQPoller recvFromServerSocket ;

 // Run the poller.
 recvFromServerPoller.Run();

Right now, the message will not be received by the C# client.

However, if I set the Python socket to zmq.DEALER, the client will receive the message, but will treat build_0 as part of the multipart message, rather than the sender ID. I need the ID to actually be accepted, as there will be multiple clients. Python dealer sockets with an identity of build_0 can communicate with the server example.

How do I set up a NetMQ DealerSocket to accept any messages from a pyzmq router socket while using identities properly?
