Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

The Expression Blend Software Development Kit (SDK) allows you to extend the capabilities of behaviors in Expression Blend.

• Microsoft Expression Blend 3 introduces 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 both Windows Presentation Foundation (WPF) and Microsoft Silverlight. For more how-to and overview information about behaviors in Expression Blend, see the Expression Blend User Guide, available when you install Expression Blend 3 + SketchFlow.
  
  The Expression Blend 3 SDK also contains the following redistributable components:
  • SketchFlow Player
  • Custom VSM for Fluid Layout
  • Font Embedding enhancements
  The Expression Blend 3 SDK is required to view an Expression Blend 3 project that uses any of these components if Expression Blend 3 is not installed.
