I Posted this Hello World Article on Atlas (of-course, now called "Microsoft ASP.NET Ajax") on Code Project a few months ago. Recently, I've been receiving multiple emails / comments telling me that the article was helpful but I should think about updating it since Atlas is undergoing a lot of changes (including the name:)).
I've spent some time during this weekend to update the article based on the Beta 2 of Atlas (Microsoft ASP.NET Ajax 1.0) and resubmitted it to CodeProject for updation. The article has been updated and is available at CodeProject.
However, if are looking for one single zip which allows you do download the latest copy of article, and source code, you can get it here. This post will be updated when further changes are made to the article.
Thanks to everyone who read the article and commented on it.
