今天微软官方正式发布了Silverlight 2正式版
安装包将延后一天发放
也就是十月十四号（也就是本周二，哪里时间没说）
在官网http://www.microsoft.com/silverlight正式放出
以前的版本将自动更新到Silverlight 2 RTW（Release To Web版本）
微软还公布了一些统计数据
比如：目前已经有1/4的电脑安装了Silverlight等等
另外还宣布了微软将对开源社区提供支持（Eclipse）
支持一：Soyatec项目http://www.eclipse4sl.org/
目前已经有一个Tech Preview提供下载
看来以后可以使用免费的Eclipse来编写Silverlight应用程序了
支持二：以后微软的新控件将采用Silverlight Control Pack (SCP)的方式发放
（有点类似Ajax开源控件那样），唯一的限制就是你需要遵循Microsoft Permissive License
目前确定会有的控件包括DockPanel, ViewBox, TreeView, Accordion and AutoComplete
这个版本具有的功能如下：
Highlights of new Silverlight 2 features include the following:
•.NET Framework support with a rich base class library. This is a compatible subset of the full .NET Framework.
•Powerful built-in controls. These include DataGrid, ListBox, Slider, ScrollViewer, Calendar controls and more.
•Advanced skinning and templating support. This makes it easy to customize the look and feel of an application.
•Deep zoom. This enables unparalleled interactivity and navigation of ultrahigh resolution imagery.
•Comprehensive networking support. Out-of-the-box support allows calling REST, WS*/SOAP, POX, RSS and standard HTTP services, enabling users to create applications that easily integrate with existing back-end systems.
•Expanded .NET Framework language support. Unlike other runtimes, Silverlight 2 supports a variety of programming languages, including Visual Basic, C#, JavaScript, IronPython and IronRuby, making it easier for developers already familiar with one of these languages to repurpose their existing skill sets.
•Advanced content protection. This now includes Silverlight DRM, powered by PlayReady, offering robust content protection for connected Silverlight experiences.
•Improved server scalability and expanded advertiser support. This includes new streaming and progressive download capabilities, superior search engine optimization techniques, and next-generation in-stream advertising support.
•Vibrant partner ecosystem. Visual Studio Industry Partners such as ComponentOne LLC, Infragistics Inc. and Telerik Inc. are providing products that further enhance developer capabilities when creating Silverlight applications using Visual Studio.
•Cross-platform and cross-browser support. This includes support for Mac, Windows and Linux in Firefox, Safari and Windows Internet Explorer.
