I've written the article about some of them: WPF and Silverlight design patterns

Here 15 is a brief description of the patterns:

1) MVVM - used 14 as a model converter and as a replacement 13 of the code-behind. Improves testability, it 12 is much easier to write unit tests for ViewModel.

2) Dependency Injection - used 11 for improving testability of a class (you 10 can write unit tests for a specific class 9 separately from others) and for the possibility 8 to change implementation in easier way (change 7 a logger, cache provider, web service etc)

3) Command - can 6 be applied to Button and MenuItem controls 5 by default, disables controls if an action 4 can't be executed. Also used in MVVM pattern 3 as a replacement of code-behind events.

Other 2 patterns from the classic book which are 1 already used in WPF:

Singleton. The Application class in WPF and the HttpContext class in Web forms.
Adapter. The data-binding engine, which uses the IValueConverter interface to convert binding values for the UI.
Decorator. The Border class, which decorates any UIElement class with a border of variable thickness and color.
Façade. The PrintDialog class, which provides a simple interface that enables you to use the entire printing and document subsystem that WPF provides.
Command. The ICommand interface, which is implemented by the RoutedCommand and RoutedUICommand classes.
Iterator. The IEnumerator interface, which many collections and lists in the .NET Framework implement.
Observer. The INotifyPropertyChanged interface and events.

Setter dependency injection:

When using MVVM you 3 have to inject an instance of ViewModel 2 into the View by setting it to the view.DataContext 1 property:

var viewModel = new CustomViewModel();
var view = new CustomView();
view.DataContext = viewModel;

Score: 1

Data binding (between View and ViewModel) uses 3 the Observer pattern. Also: the Factory 2 pattern can be used to instantiate the ViewModel 1 but that is optional.
