Creating truly cross-platform applications used to require expertise in several different programing languages. By leveraging Xamarin.Forms—a cross-platform UI toolkit—you can create native apps on iOS, Android, and Windows from a single shared code base. Mastering Xamarin.Forms Development is a nine-part series explaining how to build cross-platform mobile apps with Xamarin.Forms. In this course—the first in the series—Scott Peterson introduces platform basics such as layout and navigation, and begins building a news reader that he'll continue to develop throughout the series.
