Microsoft Expression Blend (formerly Expression Interactive Designer) helps you create streamlined, innovative and just plain beautiful applications. Users experience increased satisfaction, while you develop in a flexible, productive environment. Create engaging, cinematic user interfaces with a rich design environment that combines multiple media elements including vectors, pixel images, 3D content, video & audio, high quality text, and animation. Contextualize content by applying custom styles and layout to optimize the experience.

The Expression Blend 2 May Preview allows you to create Microsoft Silverlight-based applications. Additionally, you can export content from Microsoft® Expression® Design in a format that can be used in Silverlight-based applications that you create in Expression Blend 2 May Preview. You may also find Microsoft® Expression® Media Encoder Preview to be helpful when working with video, Silverlight, and Expression Blend 2 May Preview.
