Microsoft announced the availability of Silverlight 4 in beta at its Professional Developers Conference (PDC) today. Some of the new features include more fluid animations, Webcam, microphone and printing support, 200 percent faster start times than Silverlight 3, deep zoom and multi-touch support and more. It now also supports Google Chrome, even though it’s just a rounding error of a browser.
One of the big capabilities of Silverlight 4 is its ability to take rich-media experiences outside the browser in client apps which will compete with Adobe AIR. The non-browser apps fully support HTML, allowing tight integration with content from the Web. It also supports notifications.
