The document discusses the Model-View-ViewModel (MVVM) pattern, which is a variation of the Model-View-Controller pattern that has been popular for user interface programming. MVVM was introduced by John Gossman and takes advantage of WPF's data binding infrastructure to separate application logic and user interface. It allows testing view models independently of views and supports a smooth designer/developer workflow. View models expose command objects to handle user input and implement INotifyPropertyChanged to update bound views when properties change.

- 3. The Model-View-Presenter (MVP) pattern has enjoyed popularity on various UI programming platforms. MVP is a variation of the Model-View-Controller pattern, which has been around for decades.
- 4. Martin Fowler published an article about a pattern named Presentation Model (PM). John Gossman, currently one of the WPF and Silverlight Architects at Microsoft, unveiled the Model-View-ViewModel (MVVM) pattern
- 5. The single most important aspect of WPF that makes MVVM a great pattern to use is the data binding infrastructure. Entirely remove the need for writing code in a ViewModel that directly updates a view. Can easily write code that tests Visual designers, using MVVM makes it much easier to create a smooth designer/developer workflow.
- 6. ICommand objects exposed by the ViewModel execute. When a ViewModel exposes an instance property of type ICommand, the command object typically uses that ViewModel object to get its job done. RelayCommand is a simplified variation of the DelegateCommand
