After an introduction to the sample application used throughout this article, you'll see how applying the Presentation Model pattern insulates this application's UI and business logic layers from one another. Finally, you'll see the WPF-specific details involved in binding a Presentation Model to XAML controls to create a dynamic UI with multiple editable line items.
