This evening we published the first public release candidate of Silverlight 2.
There are still a small handful of bugs fixes that we plan to make before we finally ship. We are releasing today's build, though, so that developers can start to update their existing Silverlight Beta2 applications so that they'll work the day the final release ships, as well as to enable developers to report any last minute showstopper issues that we haven't found internally (please report any of these on the www.silverlight.net forums).
Important: We are releasing only the Silverlight Developer Runtime edition (as well as the VS and Blend tools to support it) today, and are not releasing the regular end-user edition of Silverlight. This is because we want to give existing developers a short amount of time to update their applications to work with the final Silverlight 2 APIs before sites are allowed to go live with it. There are some breaking changes between Beta2 and this RC, and we want to make sure that existing sites can update to the final release quickly once the final release is out. As such, you can only use the RC for development right now - you can't go live with the new APIs until the final release is shipped (which will be soon though).
You can download today's Silverlight Release Candidate and accompanying VS and Blend support for it here. Note that Expression Blend support for Silverlight 2 is now provided using Blend 2.0 SP1. You will need to install Blend 2.0 before applying the SP1 service pack that adds Silverlight 2 support. If you don't already have Blend 2.0 installed you can download a free trial of it here.[...]
