推荐答案

由于一些原因而发生此错误.尝试几个我知道的地方:
1.将ScriptManager的ScriptMode属性设置为Release.
2.具有AJAX相关文件参考的多个副本.仅一个参考就足够了.
3. Web应用程序较旧(.NET 1.1)，并且您尝试将其升级到新的(.NET 2.0)，其中ASP.NET中包含AJAX. Web.Config需要AJAX相关的文件引用.如果缺少它们，可能会引发"Sys"问题.创建一个启用了AJAX的新Web应用程序，然后从此处复制粘贴Web.Config.

This error happens because of few reasons. Try few I am aware of:
1. Set the ScriptMode attribute of ScriptManager to Release.
2. Having multiple copy of AJAX related file reference. Only one reference is enough.
3. Web application is old(.NET 1.1) and you tried to upgrade it to new(atleast .NET 2.0) where AJAX was included in ASP.NET. Web.Config needs AJAX related file references. If they are missing can raise ''Sys'' issues. Create a new web application AJAX enabled and then copy-paste the Web.Config from there.
