Scott Guthrie announced it January 23rd: version 1.0 of the ASP.NET AJAX extensions has been released. Good news … !
Scott also added a post containing Links to ASP.NET AJAX 1.0 resources, and answers to some common questions. A good read for people who would like to get started on AJAX. It catches some of the common problems you might encounter when you get started with the ASP.NET AJAX extensions. I liked the addition 2.0 (ASP.NET 2.0 AJAX extensions), but that’s not used everywhere. Probably because it’s kinda weird using two (different) version numbers in a single products' name after adding 1.0 for the version for the AJAX library… (full & difficult productname used here.)
