Here’s a link to the Silverlight downloads that were announced today at Mix07.
Actually at this time, the link to the Silverlight 1.0 SDK isn’t working for me. It returns an error: “The download you requested is unavailable. If you continue to see this message when trying to access this download, go to the “Search for a Download” area on the Download Center home page. ” A quick check of the MSDN Search doesn’t return a file listing for the SDK either. I’ll keep checking.
