Ajax.net 错误 Could not load type 'Microsoft.Web.Extensions.Design.Dll'解决方法.

最近开发了ajax 项目,在本地用的beta 2.0做的开发,服务器是由1.0升级到2.0的.程序发到服务器上就不行了.
Could not load type 'Microsoft.Web.Extensions.Design.Dll',系统找不到指定文件.
在国内网上基本找不到解决办法.后来上ajax的官方网站,在满篇鸟语的众多帖子中找到了解决办法.其实很多老外也被这个问题搞住了,呵呵.有很多相关帖子.回答也是多种多样.最后居然是一个不起眼的回贴解决了这个问题.我贴出来,呵呵,谢谢一下这个老外.

There is actually a very easy solution to this that I found. I traced the error back to the AjaxControlToolkit (ACTK). If you open the ACTK solution and go to the TK project within the solution, just add a reference to Microsoft.Web.UI.Design. Then, just recompile and you are finished. If you try to compile the ACTK without first doing this, you will see the error. Once I did this and referenced the new AjaxControlToolkit.dll, everything was fine.

重新引用一下AjaxControlToolkit .
