The official name as well as site is now out for Silverlight, which used to be called WPF/E. Lookin' good!
Ugh. I'm jealous. I want a 'sparkly' name. WPF is bland...as if I needed yet another acronym to prove how boring my job sounds to others. hehe.
Me) "Hi, I work in wpf."
Me) "No, doubleyou-PEE-eff...and .NET and AJAX, too."
Person) "You clean floors with that, right?"
Me) No, it's for programming.
Person) "GEEK. lollz!"
Usually the slick codename becomes a vanilla, acronym-ish official name (Avalon -> WPF, Atlas -> AJAX, Whidbey -> VS2K5, etc.). Good to see Microsoft doing it the other way around...coming up with something other than an acronym to name a new product. As a developer, I don't need the name of the product to describe what it does (Windows Presentation Foundation, Asynchronous Java and XML, etc.)...just make it SOUND interesting! Just say NO to alphabet soup! ;)
