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

Xamarin has a C#-shared codebase and developers can use its tools to write native Android, iOS, and Windows apps with native user interfaces and share code across multiple platforms like Windows, macOS, and Linux. Microsoft announced in February 24, 2016 that it had signed a definitive agreement to acquire Xamarin. To learn more about Xamarin, go to the Xamarin home page.
