We are going to need some packages. The packages will only need to be added to the common project: SignalRChat.Mobile. First, let's add a reference to SignalR by adding the package called Microsoft.AspNet.SignalR.Client. After this, add a reference to SimpleInjector, a simple IoC container implementation. We could have used Ninject or others here as well. There are, however, some limitations with some of the magic that was going on when we used Ninject together with Bifrost that is yet to be solved by these libraries; therefore, we just use this for simplicity instead.
