在Ajax框架中，Asp.net方面最强当属Altas最强，以前使用AjaxPro.
Net和MagicAjax. 最几个都比较好用。这几个月来Altas已经进入CTP版本，是开始学习研究Altas的时机了。准备利用Altas为 http://www.yupsky.com 开发成员之间在线通讯的类似于MSN这样的功能。今天初步的学习了一下Altas，最基础的学习内容就是使用javascript调用服务端代码。
Altas和AjaxPro.Net类似，但比AjaxPro.Net强大很多。学习结果记录如下：
程序的原型来自http://weblogs.asp.net/scottgu/archive/2005/09/14/.aspx，但是这个是beta版时候的教程。
1、下载altas框架，到http://www.asp.net/default.aspx?tabindex=8&tabid=47上去下载，上面有很多内容
2、使用VS2005创建一个WebSite或者Web Application.
3、配置Web.config如下：

Step 1: 产生一个Web服务 推荐使用WebService atlas使用webService时，对于webService并没有特殊要求
