A Uno flavor of Xamarin.Essentials to help developers transition to Uno

Xamarin.Essentials gives developers essential cross-platform APIs for their mobile applications. But it and Xamarin.Forms is going away. That gives developers a chance to reflect upon what Cross Platform XAML framework would be best for their applications - and, if you're actually willing to consider that question, the answer is going to be UNO.

The library is a port of Xamarin.Essentials for use with the Uno Platform. It is intended as a bridge for developers as not all the features and functions of Xamarin.Essentials has implementations in WinUI.


iOS, Android, and UWP offer unique operating system and platform APIs that developers have access to, all in C# leveraging Xamarin. It is great that developers have 100% API access in C# with Xamarin, but these APIs are different per platform. This means developers have to learn three different APIs to access platform-specific features. With Xamarin.Essentials, developers have a single cross-platform API that works with any iOS, Android, or UWP application that can be accessed from shared code no matter how the user interface is created.
