Silverlight 2 RC0 is out

The first public release canditate (RCo) for Silverlight 2 is now available for download by developers. While anyone can install it, the main goal is for developers to make sure they aren't hit by any breaking changes for Silverlight 2 RTM so they can fix any issues. No one will be auto-updated to this release. Users will be auto-updated to Silverlight 2's final release when it's posted.

All Silverlight 1.0 projects should work fine, but there may be some Silverlight 2 Beta projects that require updates.

For the media folks, there's a couple of new things I want to mention.
  • There's a new scaling algorithm that's a lot faster and much higher quality - a nice compromise when you can get it!
  • Additional optimizations have been done for the VC-1 video decoder, so playback will be faster. The gains are biggest for content using B-frames.

Since the default Expression Encoder templates have "always on" scaling and its presets use B-frames by default, the above will provide a nice performance boost for existing content. The above are "always on" features - you don't need to update anything to take advantage of them. So expect smoother frame rates on lower-end machines.
