Xamarin Forms

Xamarin.Forms - Write Once, Run Everywhere, 

AND Be Native?

Xamarin.Forms is a platform to develop cross platform mobile applications by using XAML for front-end and C# for backend of the application. In Xamarin.Forms applications, all your code is shared . Also, it gives 100% API coverage of Android and iOS native APIs. So, you can develop native Android, iOS and Windows apps.

Xamarin is a Microsoft-owned San Francisco, California-based software company founded in May 2011 by the engineers that created Mono, Mono for Android and MonoTouch, which are cross-platform implementations of the Common Language Infrastructure (CLI) and Common Language Specifications (often called Microsoft .NET).

With a C#-shared codebase, developers can use Xamarin tools to write native Android, iOS, and Windows apps with native user interfaces and share code across multiple platforms, including Windows and macOS. According to Xamarin, over 1.4 million developers were using Xamarin's products in 120 countries around the world as of April 2017.
