But before you can start using an asynchronous programming model in your WPF application, it is important that you understand the WPF threading model. In this article I will not only introduce you to that threading model, but I'll also show you how the Dispatcher-based objects work and explain how to use the BackgroundWorker so that you can create compelling and responsive user interfaces...

It assumes you are familiar with basic WPF data binding techniques as well as design patterns that object-oriented UI libraries typically use. 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.
