Calling a server-side Hub method

After learning how to perform a connection and customize the transport strategy, let's move to the natural next step: calling a server-side Hub method. As we have done so far in this chapter, we'll use the SignalR dynamic proxy generation feature that allows us to perform client-to-server calls in a more natural way. The alternate available approach will be illustrated in the future recipes.

This recipe and the remaining ones of this chapter have a clear goal of illustrating the client-side code in a very detailed way, and that's because we have several important features to explain. For this reason, we'll show the code and comment on it step by step, instead of going directly to its final version and commenting on it afterwards.

How to do it…

Let's proceed to the code, starting with the server side. Perform the following steps:

1. We first need to add a Hub, which we call EchoHub, and add the following code to it:

    using Microsoft.AspNet.SignalR;
    using Microsoft...
