Those of you, who visited my session on Windows Presentation Foundation, hopefully remember speaking about WPF/E - a lightweight XAML based technology for developing interactive webapplications.
As I mentioned in my speech, Windows Presentation Foundation / Everywhere was not the perfect codename, because WPF/E is technically totally different from the desktop WPF!
This was a hidden hint, to what was announced now: Codename "WPF/E" will be called Microsoft Silverlight from now on!
You find more information on these blogs:
One additional hint: Expect more announcements about the featureset of Silverlight around the MIX conference (at the end of April).
