Don't miss Scott Guthrie's post on today's release of ASP.NET AJAX 1.0. In it, he discusses what's been released, changes from the most recent beta, and drops the news that all source code for ASP.NET AJAX 1.0 will be made available. The client side code is available for modification, and the server side code is available for reference, and to assist in debugging. See Scott's post for the details.
