This is the only book available targeting the popular MVVM development framework with a focus on Xamarin.Forms. It presents clear examples of the advantages of MVVM along with step-by-step demonstrations of how to create a number of applications which gain in complexity. It covers application development for iOS, Android and Windows Phone using mvvmlight and mvvmcross as the libraries.

The Model-View-View-Model (MVVM) pattern is valued by many developers as an excellent way of creating sophisticated modern applications. Its clear separation of presentation and business logic produces a clean implementation that promotes speed, scalability and code reuse in applications with a complex UI. These characteristics have long been highly valuable to WPF developers, and now that benefit is available to Xamarin developers too.
