With more than 300 million devices running Windows 10 it is clearly time for any smart client application to target Windows in addition to iOS and Android. The Universal Windows Platform (UWP) allows you to write common code that supports Windows 10 PCs, tablets and phones, as well as Xbox and Hololens. This UWP app leverages the same client-side business logic as the Xamarin.Forms app, and the same server-side services as all the other client implementations.
