A framework for building loosely coupled, maintainable, and testable XAML applications across WPF, Avalonia, MAUI, and Uno Platform.
Prism is a framework for building loosely coupled, maintainable, and testable XAML applications across multiple platforms, including WPF, Avalonia, MAUI, and Uno Platform. It provides an implementation of design patterns like MVVM, dependency injection, and commands to help developers create scalable and well-structured desktop and mobile applications. The framework addresses the complexity of managing UI logic and business logic separation in large XAML-based projects.
Developers building enterprise-grade desktop or mobile applications with XAML technologies like WPF, Avalonia, MAUI, or Uno Platform who need a structured approach to maintainability and testability.
Developers choose Prism for its comprehensive implementation of proven design patterns, cross-platform support, and strong focus on loose coupling and testability, which reduces long-term maintenance costs and improves code quality in complex XAML applications.

Prism provides a full-featured implementation of the Model-View-ViewModel pattern with commands and data binding, ensuring clean separation of concerns as highlighted in the key features for maintainable XAML apps.
With tailored libraries for WPF, Avalonia, MAUI, and Uno Platform sharing a common .NET Standard core, Prism delivers a consistent development experience across desktop and mobile XAML environments.
The framework includes modularity features that allow applications to be decomposed into independent, testable modules, facilitating scalable architecture as described in the modularity section.
Prism seamlessly integrates with popular IoC containers like DryIoc and Unity via specific NuGet packages, enhancing testability and loose coupling without extra configuration.
Since version 9.0, Prism uses a dual license system where larger organizations must purchase commercial licenses, adding cost and administrative overhead compared to fully open-source alternatives.
The Prism Team no longer supports StackOverflow, redirecting all questions to GitHub Discussions, which may limit accessibility to quick answers and community-driven help.
Samples for newer platforms like Uno and MAUI are marked as 'coming soon' in the README, indicating gaps in documentation and resources that could hinder adoption for early projects.
