Expression Blend 4 SDK for .NET 4 & Silverlight

Microsoft Expression Blend 4 includes new built-in behaviors, which are reusable pieces of packaged code that can be dragged onto any object, and then fine-tuned by changing their properties. Behaviors allow you to add interactivity to your applications without having to write any code. The Behavior API consists of three core classes: Trigger, Action and Behavior. This SDK explores how to write each of these components, and contains a few code samples to help you get started. Programming reference topics are provided for Windows Presentation Foundation (WPF). For more how-to and overview information about behaviors in Expression Blend, see the Expression Blend User Guide, available when you install Expression Blend 4.

The Expression Blend 4 SDK also contains the following redistributable components:

  • SketchFlow Player
  • Custom VSM for Fluid Layout
  • Font Embedding enhancements
  • Effects and Transition Effects
  • Shapes

The Expression Blend 4 SDK is required to edit an Expression Blend 4 project that uses any of these components if Expression Blend 4 is not installed.
