Xamarin.Forms lets you define your UI using the eXtensible Application Markup Language (XAML). This gives you a clean separation of UI and behavior and makes it easy to utilize a design expert and design tools. This course shows you how to define your UI in XAML. You will create pages and add controls, all in markup. You will also see how to access UI elements from code so you can subscribe to UI events and update UI properties as your data changes.
