Win Application Framework (WAF)

Successor of the WPF Application Framework

The Win Application Framework (WAF) is a lightweight Framework that helps you to create well-structured XAML Applications (MAUI, Xamarin, WPF, WinUI). It supports you in applying various architectural patterns:

• Layered Architecture
• Model-View-ViewModel Pattern
• DataModel-View-ViewModel Pattern

How to get started?

• WAF comes with realistic real-world sample applications. Please have a look at them. See Sample Applications below.
• The Wiki provides further guidance.

Supported Platforms

• *.Core (.NET 6.0 and .NET Standard 2.0): Support for all .NET based applications.
• *.Wpf (.NET 6.0 and .NET Framework 4.7.2): Extended support for Windows Presentation Foundation (WPF).
