Microsoft's former Silverlight Product Manager Scott Barnes, now a user experience specialist at Australian development consultants Readify posted a series of tweets. According to Barnes, there's intense internal debate about the future of HTML 5, newly implemented in forthcoming IE9, and Silverlight plug-in. He tweeted: "Right now there's a faction war inside Microsoft over HTML5 vs Silverlight. oh and WPF is dead.. i mean..it kind of was..but now.. funeral."
WPF, the rich user interface framework that was originally intended to become the primary GUI API for Windows Vista, but was sidelined when Vista development was "reset" in 2004, and doesn't feature strongly in Windows 7. "There's no-one working on it beyond minor touch-ups," Barness says.
