silverlight beta 2 将在本周末发布.

太开心了,刚刚收到微软silverlight.net的邮件.  确定了 将在本周末发布beta2.

以下是部分邮件内容

There are some new features we’re announcing at this time that will be included in Beta 2:

·         UI Framework: Beta 2 includes improvements in animation support, error handling and reporting, automation and accessibility support, keyboard input support, and general performance.  This release also provides more compatibility between Silverlight and WPF.



·         Rich Controls: Beta 2 includes a new templating model called Visual State Manager that allows for easier templating for controls. Other features include the introduction of TabControl, text wrapping and scrollbars for TextBox, and for DataGrid additions include Autosize, Reorder, Sort, performance increases and more.  Most controls are now in the runtime instead of packaged with the application.



·         Networking Support: Beta 2 includes improved Cross Domain support and security enhancements, upload support for WebClient, and duplex communications (“push” from server to Silverlight client).



·         Rich Base Class Library: Beta 2 includes improved threading abilities, LINQ-to-JSON, ADO.NET Data Services support, better support for SOAP, and various other improvements to make networking and data handling easier.



·         Deep Zoom: Beta 2 introduces a new XML-based file format for Deep Zoom image tiles, as well as a new MultiScaleTileSource that enables existing tile databases to utilize Deep Zoom. Better, event driven notification for zoom/pan state is another improvement in Silverlight 2 Beta 2.  

另外说一下.beta2 的改动不小. 复杂点的应用移植可能要费些事了.
