Today we shipped the final release of Silverlight 2. You can download Silverlight 2, as well the Visual Studio 2008 and Expression Blend 2 tool support to target it, here. Silverlight 2 is a major release that enables some great new application and media experiences to be built, and allows developers to use .NET within any browser to create them.
Cross Platform / Cross Browser .NET Development
Silverlight 2 is a cross-platform browser plugin that enables rich media experiences and .NET RIAs (Rich Internet Applications) within the browser.
Silverlight 2 is small in size (4.6MB) and takes only 4-10 seconds to install on a machine that doesn't already have it. It does not require the .NET Framework to be installed on a computer to run - the Silverlight setup download includes everything necessary to play video or run applications.
* WPF UI Framework: Silverlight 2 includes a rich UI framework that makes building rich Web applications much easier. In includes a powerful graphics and animation engine, as well as rich support for higher-level UI capabilities like controls, layout management, data-binding, styles, and template skinning. The WPF UI Framework in Silverlight is a compatible subset of the WPF UI Framework features in the full .NET Framework, and enables developers to re-use skills, controls, code and content to build both rich cross browser web applications, as well as rich desktop Windows applications.
* Rich Controls: Silverlight 2 includes a rich set of built-in controls that developers and designers can use to quickly build applications. The Silverlight 2 release includes core form controls (TextBox, CheckBox, RadioButton, ComboBox, etc), built-in layout management panels (StackPanel, Grid, Panel, etc), common functionality controls (Slider, ScrollViewer, Calendar, DatePicker, etc), and data manipulation controls (DataGrid, ListBox, etc). All Silverlight controls support a rich control templating model, which enables developers and designers to collaborate together to build highly polished solutions.
* Rich Networking Support: Silverlight 2 includes rich networking support. It includes out of the box support for calling REST, WS*/SOAP, POX, RSS, and standard HTTP services. It supports cross domain network access (enabling Silverlight clients to directly access resources and data from resources on the web). It also includes built-in sockets networking support.
* Rich Media Support: Silverlight 2 includes built-in video codecs for playing high definition video, as well as for streaming it over the web (including both live and on-demand support). Silverlight includes support for adaptively switching video bitrates on the fly based on network conditions (enabling users to avoid seeing the dreaded "buffering..." message), placing and metering ads within video streams, as well as enabling content protection.
The final Silverlight 2 release delivers a tremendous amount of power and flexibility that enables you to really push the boundaries of what can be done in a browser, and enable great end user experiences.
Over the last few months a number of very high profile sites have successfully launched using the beta releases of Silverlight 2.
In August, NBC hosted the Olympics live on nbcolympics.com and served up 1.3 billion page views, 70 million video streams, and 600 million minutes of video content - making it the largest ever media event on the web. Users visiting the site spent an average of 27 minutes on the site when they watched a video - an unprecedented number for online traffic.
In August, the Democratic National Convention was streamed live using Silverlight, and broadcast a 2Mbit live video feed of the event and speeches - receiving outstanding feedback from audiences watching it.
This month a number of other high profile sites are going live with the final release of Silverlight 2. CBS College Sports Network will be streaming 20,000 hours of live games for 150+ college and university partners. AOL is launching their new AOL Mail browser version to 60 million users using Silverlight 2. Blockbuster will be launching their new MovieLink subscription service using Silverlight. Yahoo! Japan is live today enabling live streaming of Major League Baseball games. Hard Rock International will be updating their memorabilia site with new features. And companies like Toyota, HSN and hundreds of others will be live this week as well.
Silverlight 2 ships with dozens of built-in UI controls that can be used to build applications. Below is a screen-shot of the Silverlight DataGrid, RadioButton, CheckBox and DatePicker controls in the final release:
Today we are also announcing the "Silverlight Toolkit" - which will deliver dozens of more controls that you can use with Silverlight 2. We will continually add new controls to the control pack over the next few months (we expect to ultimately have more than 100 controls total). The first release of the toolkit will include controls like TreeView, DockPanel, WrapPanel, ViewBox, Expander, NumericUpDown, AutoComplete and more. All controls will ship with full source, and with a OSI license that allows you to modify and use the source for any purpose. Interoperability
Today we are also announcing that Microsoft is partnering with Soyatec to sponsor additional tools for developing Silverlight applications using the cross platform Eclipse development platform.

We are also announcing today that we are releasing the Silverlight XAML vocabulary and schema under the Open Specification Promise (OSP), which enables anyone to create products that read and write XAML for Silverlight.
