Prototypes are extremely useful, but can be expensive and time consuming to create - especially if you are asked to create them for multiple platforms. In this session, you will be introduced to wireframes, mockups, and prototypes and learn about their differences. We will then talk through the features of Xamarin.Forms that make it a powerful tool for prototyping. You will see how you can use Xamarin.Forms and XAML to write a few lines of code in one file that will create a UI with native controls on all three major mobile platforms. We will wrap up with a live demo that shows how to create a Xamarin.Forms prototype application that will run natively on iOS, Android, and Windows Phone with 100% code sharing.
