The Microsoft Expression Blend Software Development Kit (SDK) provides conceptual topics for behaviors, which are reusable pieces of packaged code that can be dragged onto any object and then fine-tuned by changing their properties. The SDK also includes a programming reference for other extensibility features in Expression Blend, such as controls, drawing features, and effects.

important note Note:

Because the Expression Blend SDK is provided to you "as-is," support services may not be provided for it. Microsoft may provide updated components to the SDK in the future. To check for updates, see Microsoft Help and Support.

Working with behaviors

Expression Blend includes a variety of built-in behaviors. You can use behaviors to add interactivity to your applications without having to write any code.

You can use the Expression Blend SDK to extend the capabilities of behaviors in Expression Blend. The Behavior API consists of three core classes: Trigger, Action, and Behavior. This SDK explains how to write each of these components, and contains a few code samples to help you get started. Additional content about some behaviors is available at the following locations:
