The PRISM RegionAdapter for the WPF Ribbon Control
A RegionAdapter for the Ribbon native WPF control for the PRISM composite WPF application block.
Prism provides an implementation of a collection of design patterns that are helpful in writing well structured, maintainable, and testable XAML applications, including MVVM, dependency injection, commanding, event aggregation, and more. Prism's core functionality is a shared library targeting the .NET Framework and .NET. Features that need to be platform specific are implemented in the respective libraries for the target platform (WPF, Uno Platform, .NET MAUI and Xamarin Forms). Prism.Forms.Regions helps you more easily design and build rich, flexible, and easy to maintain Xamarin.Forms applications by bringing class WPF Regions to Xamarin.Forms. This library provides the IRegion and RegionManager. While we support a number of standard Xamarin.Forms controls like StackLayout & ContentView, you can provide custom RegionAdapters to make Regions work with any control that you like.
