Xamarin Forms allows developers to easily create native mobile apps for Android, iOS, and Windows using C# and shared code. It uses XAML and C# to build user interfaces that render natively on each device for a native experience with a lower development cost compared to building each app separately. Xamarin Forms has a large community for support and its use of C# and the .NET framework reduces the learning curve for mobile development.
