Prism.Container.Abstractions by: Brian Lagunas, Dan Siegel

This package provides the core Dependency Injection Container abstractions that the Prism Library depends on for all WPF, Xamarin.Forms, .NET MAUI, and Uno Platform applications.

Prism.Container.DryIoc by: Brian Lagunas, Dan Siegel

This package provides the DryIoc implementation for the Prism Library IContainerExtension for use in any Prism based application.

Prism.Core by: Brian Lagunas, Dan Siegel

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, commanding, event aggregation, and more. Prism's core functionality is a shared code base in a class library that does not target any specific Application Framework. Features that need to be platform specific are implemented in the respective libraries for the target platform.

Prism.DryIoc.Forms by: Brian Lagunas, Dan Siegel

Use these extensions to build Xamarin.Forms applications with Prism and DryIoc.

Prism.Events by: Brian Lagunas, Dan Siegel

Prism.Events is a library that facilitates communication between loosely coupled components in an application. It provides an event aggregator service that allows publishers and subscribers to interact through events without direct references. With multicast publish/subscribe functionality, multiple publishers can raise the same event, and multiple subscribers can listen to it, enabling flexible and efficient communication.

Prism.Forms by: Brian Lagunas, Dan Siegel

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 for Xamarin.Forms helps you more easily design and build rich, flexible, and easy to maintain Xamarin.Forms applications. This library provides user interface composition as well as modularity support.
