Woo - Hoo!!
Navigate over to http://silverlight.net/GetStarted/ to download the freshly minted beta 2 bits including the runtime, the SDK, and the Visual Studio 2008 tools for Silverlight 2 development. There is also a brand new version of Blend 2.5 preview and a new version of the Deep Zoom Composer available for download as well.
I have been quite busy working on several large customer projects that involve Silverlight 2 Beta 2. In the coming weeks do visit here to find more tid-bits about SL 2 development and the changes in Beta 2.
