Calling back the caller from a Hub's method
With this recipe, we are actually starting to look at more interesting and real-time SignalR features. We will see how a Hub can call back into a client that just performed a remote method call.
Getting ready
Before starting with this recipe, we need to create a new empty web application, which we'll call Recipe06.
How to do it…
Let's start building the server-side portion of this recipe using the following steps:
We must first add a Hub called
EchoHub.We must then add an OWIN Startup class named
Startup, containing just a simpleapp.MapSignalR();bootstrap call inside theConfiguration()method.Let's make the Hub's content look like the following:
