Xamarin software enables the development of cross-platform mobile applications using C#. This course covers creating separate Xamarin Android and iOS projects in Visual Studio that can share code within a single solution. It covers how to create a Xamarin.Android project, how to add controls and work with images and how to use the Android emulator. It also covers how to create a Xamarin.iOS application, use the iOS Designer to add controls, work with layouts and images, and connect to a Mac build host to use an iOS emulator.
