ASP.Net AJAX 1.0 Release Candidate
Last week, the ASP.Net AJAX team took a major step towards getting web developers closer to moving their web applications based on ASP.Net AJAX into production with the release of the RC (the AJAX Futures Dec CTP has also been made available). The release also further aligned ASP.Net AJAX with previous ASP.Net releases by changing the namespace from Microsoft.Web.* to System.Web.* and also the assembly name changing from Microsoft.Web.Extensions* to System.Web.Extensions* (this also helps in aligning the 1.0 with future Framework releases).
I would encourage everyone to move to the RC and provide feedback to the team via the forums.
