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 in WPF and UWP. It supports you in applying various architectural patterns:

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.
The fastest way to create a WAF project is by using the WAF Visual Studio Project Template. Please update the WAF NuGet packages to the latest stable version after project creation.
