Hot on the heels of Flash 10.1, Microsoft unveils Silverlight 4 beta

Get Microsoft Silverlight
Microsoft has been busy churning out news at PDC09, already having announced the arrival of Office 2010's public beta and Internet Explorer 9.

Not to be done by Adobe's recent unveiling of Flash 10.1, Microsoft has taken the wraps off Silverlight 4 beta. A few of the key changes in the new version include support for Google Chrome, performance gains up to 200% over Silverlight 3, and multi-touch support.

Silverlight's Deep Zoom has also been turbo-charged with hardware acceleration. v4 can also tap into your webcam and microphone, and local recording capabilities have been added. Microsoft hopes Silverlight 4 will allow developers to go beyond the browser and create rich desktop applications -- another salvo at the Adobe camp.

There are a slew of additions and enhancements aimed at developers, network administrators, and kiosk environments -- you can check a complete listing out in the offical release announcement.

Can't see the video embed in this post? You need to get your hands on the Silverlight plugin, I reckon. Runtimes are available for Windows and Mac here.
