We just released the initial version of an architectural framework for Windows Presentation Framework (WPF) that makes use of the Presentation-Abstraction-Control (PAC) pattern. This framework is meant to be used for any .NET 5 projects that are building WPF applications.
The release contains type definitions for implementation generically, WPF-specific type definitions, and CodeFactory automation commands and helpers for building your final code artifacts.
Please see the following link for more details of the open-source project:
