Build 3.0.40624.0 Released July 9, 2009

Highlights of new features include the following:

·         Smooth Streaming dynamically detects and seamlessly switches, in real time, the video quality of a media file delivered to Silverlight based on the consumer’s local bandwidth and CPU conditions. This provides support for live and on-demand true HD (720p+) HTTP-based adaptive streaming.

·         Perspective 3D graphics allows any content to be placed a 3D plane, and still be live: video play and controls are still functional. You can rotate or scale live content in space without writing any additional code. Other effects include creating a queue in 3D and transitions.

·         Pixel Shader effects such as blur and drop shadow make content stand out in the page. They can be applied to any graphical content and also animated, for instance to make a button appear depressed on rollover you could use a drop shadow effect on the pressed visual state.

·         New Controls - Silverlight 3 is packed with over 60 high-quality, fully Skinable and customizable out-of-the-box controls such as charting and media, new layout containers such as dock and ViewBox, and controls such as AutoComplete, TreeView and DataGrid. The controls come with nine professional designed themes and full source code.

·         The new Out-of-Browser experience built into Silverlight 3 lets users place their favorite Silverlight applications directly onto any PC or Mac desktop. This is a radical improvement over traditional RIA offerings that have separate technologies for browser and desktop. Furthermore, the new experience enables Silverlight applications to work whether the computer is connected to the Internet or not.

·         Extensible media format support with RAW AV - The new Raw AV pipeline provides support for a wide variety of third-party codecs. Audio and video can be decoded outside the runtime and rendered in Silverlight, extending format support beyond the native codecs, adding support for features such as alpha video. 

·         Deep Zoom technology in Silverlight allows users to see images on the Web as never before. The smooth, in-place zooming and panning that Deep Zoom allows is a true advancement and raises the bar on what image viewing should be. It is also now possible through this feature to make super-high-resolution images easily consumable on the Web.

·         Skinning & Styling in Silverlight makes it easy to create graphics and then use them to customize controls, such as the look of a scrollbar or chart. Silverlight provides XAML based templates for each control that allow designers to reach inside the control and change the layout or look of each part of the control without rewriting any code. For example, a scrollbar is made up of a layout container and a set of parts such as the up and down button and draggable thumb. Parts can be rearranged and their appearance changed to fully customize the control. In addition, controls can be themed by applying a style to offer a range of different colors or font sizes.

·         SketchFlow, part of Expression Studio 3, revolutionizes the speed and efficiency you can demonstrate a vision for an application. SketchFlow provides an informal and quick way to explore, iterate and prototype user interface scenarios allowing you to evolve your concepts from a series of rough ideas into a living breathing prototype that can be made as real as a particular client or project demands. This rapid, iterative and cost effective approach to prototyping allows you to concentrate on what matters most, being creative and building the best solution for your client, on time and within budget.
