Xamarin.Android - How To Set Time Android Application Using Visual Studio 2017

What are Xamarin and Xamarin Forms?

  • Xamarin is a cross-platform to develop multi-platform Applications
  • Xamarin is a Shared code(C#), But Separately Design UIs Android(java), Windows(C#), IOS (Objective C & XCODE).
