ASP. NET AJAX Primer Series (1): overview

A friend who often pays attention to my blog may have noticed that in my blog's left series, I have removed the recommendation for the Atlas Learning Notebook series, because with the release of the ASP. NET AJAX 1.0 beta release, they no longer apply, in order not to continue to mislead the vast number of friends, So no longer as a recommended series of articles, if you need to refer to friends, you can directly to the essay category to view.

The ASP. NET AJAX beta changes were so large that, given the lack of good Chinese references, I decided to start writing the ASP. NET AJAX Starter Series, which I would treat as a whole new thing with ASP, no longer considering the previous Atlas, The study of ASP. NET AJAX to share with you, easy to beginner friends to take a few detours. Friends who are familiar with Atlas can recommend seeing Dflying Chen's embrace change-from atlas to the ASP-Ajax series, as well as Lao Zhao's Deep Atlas series. Because of the personal ability and the degree of mastery is limited, there are inevitably errors and omissions in the place, but also ask you to understand and correct.

OK, let's start from here!
