Prism is a framework for building loosely coupled, maintainable, and testable XAML applications in WPF, Windows 10 UWP, and Xamarin Forms.

Prism is an open source framework for building loosely coupled, maintainable, and testable XAML applications in WPF, Windows 10 UWP, and Xamarin Forms.

Prism provides an implementation of a collection of design patterns that are helpful in writing well-structured and maintainable XAML applications, including MVVM, dependency injection, commands, event aggregation, and others.

Prism's core functionality is a shared code base in a Portable Class Library targeting these platforms. Those things that need to be platform specific are implemented in the respective libraries for the target platform.

Prism also provides great integration of these patterns with the target platform. For example, Prism for UWP and Xamarin Forms allows you to use an abstraction for navigation that is unit testable, but that layers on top of the platform concepts and APIs for navigation so that you can fully leverage what the platform itself has to offer, but done in the MVVM way.

For more information visit the project site https://github.com/PrismLibrary/Prism.

You can find the latest documentation here.
