This document discusses building real-time cross-platform apps with SignalR and Xamarin. It describes Xamarin as allowing development of native Android, iOS, and Windows apps using C# and sharing code. SignalR is introduced as simplifying adding real-time functionality by allowing server code to push content instantly to clients. The document notes that the SignalR .NET client works for Xamarin apps as well as JavaScript, allowing cross-platform real-time apps to be created using these technologies.

13. MvvmCross
This project provides a cross-platform mvvm mobile development
framework built on top of:
• Silverlight for WP7, WP8
• Mono for Android (or Xamarin.Android)
• MonoTouch for iOS (or Xamarin.iOS)
• the WinRT XAML framework for Windows 8 Store apps
• Windows Universal projects (WPA8.1 and Windows 8.1 Store apps)
• WPF
• Mono for Mac (or Xamarin.Mac)
This project makes extensive use of Portable Class Libraries to
provide maintainable cross platform C# native applications.

17. What is SignalR?
ASP.NET SignalR is a library for developers that
simplifies the process of adding real-time web functionality to
applications. Real-time web functionality is the ability to have
server code push content to connected clients instantly as it
becomes available, rather than having the server wait for a
client to request new data.

19. Xamarin Client
The ASP.NET SignalR Client not only works in
JavaScript and browsers, but also .NET applications such as
Xamarin.Android, Xamarin.iOS, Windows Phone and Windows
Store. The .NET client uses the System.Net.Http namespace to
connect to a SignalR server.
