How to use WCF service using dual wsHttpBinding in signalR?

Hi,

You definitely don't need wsDualHttpBinding to return values. BasicHttpBinding or even better WSHttpBinding is what you need

wsDualHttpBinding is used to actually call the client from the server (callbacks). It's something which isn't widely used in the web world because it has limitations and there are better options like WebSockets and SignalR.

You can refer following links for better understanding.

thanks
