Xamarin. Forms – Gill Cleeren
Xamarin.Forms is the embodying of Microsoft’s idea of writing code once and running it on a multitude of devices. Using XAML and C#, existing .NET developers can easily build iOS, Android and UWP applications, all sharing a maximum amount of code. While the framework is rather complete, developers will need to go off the beaten track and write controls and native interactions with features of the devices, for which native Xamarin will be used.
