Microsoft may halt development work on Silverlight plugin after next release
It's not just Adobe that's altering its plans when it comes to browser plugins designed to play back rich web media — Microsoft's joining in too. New releases of Silverlight, Redmond's big competitor to Flash Player, are reportedly going to be abandoned after the launch of Silverlight 5, expected later this month. This information comes from multiple sources cited by the usually well-informed Mary Jo Foley. They don't know how long Microsoft will maintain support for Silverlight 5 or if there'll be any service packs, but it does seem like the company will be switching its operational focus to other areas and halting active development of Silverlight.
