...Microsoft for the official product name for a sub-set of WPF technology previously known under the code name WPF/E: Silverlight. Sure, it's a catchier name than WPF/E (for non-geeks), but I seriously wonder if it will help to turn it into the Flash killer it wants to be. You can read more on Soma's Blog about the announcement they made at the NAB conference in Las Vegas, and you can also check out my previous post on the early preview versions of WPF/E. Other tech blogs will have similar announcements over the next couple of days, but Brad Abrams from the Microsoft .NET Ajax team and Nikhil Kothari both posted their first comments already. The otherwise boring Silverlight website has one nice section in form of a collection of blogs that cover the technology behind Silverlight.
Update 4/30/2007: Today at Mix07 some Silverlight related downloads and technologies were announced (read here and here for details). Hit the links for details:
