我认为您使用的是2.0框架&现在您已将该项目转换为3.5框架.
因此，您的应用程序正在寻找System.Web.Extensions.dll(2.0框架版本).要解决此问题，请从web.config&中删除元素<sectiongroup name="system.web.extensions" ........=""></sectiongroup>(2.0框架版本).使用添加引用将System.Web.Extensions.dll(3.5框架版本)文件添加到您的应用程序.

I think you were using the 2.0 framework & now you have converted that project into 3.5 framework.
So your application is looking for System.Web.Extensions.dll(2.0 framework version). To fix this, remove the element <sectiongroup name="system.web.extensions" ........=""></sectiongroup>(2.0 framework version) from web.config & Add the System.Web.Extensions.dll(3.5 framework version) file to your application using Add Reference.
