From what I can see this VD was released 19/09/2008 however I have found that Microsoft Date Published dates are not always correct – unless I’m wrong surely not!
Any way the vhd here:
Is a time limited evaluation VHD containing WSS 3.0 SP1, Visual Studio 2008 and the VS 2008 extensions for VS WSS 3.0, v1.1, Yippee.
What is cooler is that it has Silverlight 2.0 Beta 2 (build 2.0.30523.8) and the matching version of Visual Studio SilverLight tools.
Something tells me that we are going to see SilverLight based tools in SharePoint 2010,
