Xamarin, founded in 2011, is a cross-platform development solution that can help simplify development processes by enabling developers use C# to build Android, iOS, and Universal Windows applications with native UIs and share code across several platforms like Windows and Mac OS.

It can be downloaded with Visual Studio and developers can directly create Windows, iOS, or Android apps with since Visual Studio itself. Since, Xamarin permits writing codes in C#, there is no need for developers Swift, Objective-C or Java to build apps once you understand C#. Xamarin is very good for beginners in app development.
