WPF Designer sample code is posted

If you want to author custom design-time experiences for your WPF controls, this is a good place to start.

We have samples for custom adorners, context menus, property value editors, and advanced scenarios. This code is written for Visual Studio 2010 Beta 2, but you should have luck with the Beta 1 bits. A Silverlight example is in preparation but isn’t posted yet.

Check out the code here: WPF and Silverlight Designer Extensibility Samples.

UPDATE: The following list shows the features that are supported by both Visual Studio 2010 and Expression Blend.

  • Adorners
  • Context menus
  • DesignModeValueProvider
  • Default initializers
  • All of the ModelItem features, such as selection manipulation.
  • Property grid extensibility (same as Blend 2)
