问题
I have created a WCF duplex service and client in .NET and its working fine and its pretty good also.
Now I wish to make an Android client. I have used kSoap previously for webservices and those are good for client to service connections.
But in the case of duplex communication in which I need the service to sent message to client, I dont know how to implement.
回答1:
Unfortunately none of the duplex bindings are interoperable
At this point polling might be your simplest option. Further down the line maybe you could use something like WebSockets (WCF supports them in the next version - 4.5)
