I am happy to say we announced that WPF/E will now be called Silverlight. I dig the name and the logo rocks, but you may be wondering if it really works. Have no fear :) Check out some of the samples in the SDK that show the real power of this new technology. This one is near and dear to my heart because I did a session on WPF/E as my "audition" to get into MS. I was really impressed with the range of features that were already available in a CTP.
Make sure to visit the Silverlight Product Site to get all kinds of cool stuff!
