Have you been following the evolution of the technology that was previewed under the codename 'WPF/E'?  Well, it now has an official name, and that name is Silverlight.  Silverlight is a cross-platform, cross-browser solution for delivering rich, interactive applications and media experiences on the web.

I'm particularly excited about the tools support around Silverlight -- in particular the Expression product suite and Visual Studio.  I believe Microsoft's rich tool support will be a key differentiator between Silverlight and other competing technologies.

Silverlight is currently available as a CTP; a beta will be available at MIX 07.  For more details, head on over to Soma's blog.
