C# 降级到.net 2.0时出现JScript错误

我创建的Web应用程序项目有问题。最初我是在.NET3.5中开发的，一切正常。后来有人告诉我，它必须在.NET2.0（叹气）中，这不仅导致了我编写的LINQ内容出现问题，而且现在还产生了一个奇怪的JScript错误。每当我单击UpdatePanel中的按钮时，就会发生此错误。错误在其中一个ScriptResource.axd文件中。错误是：

Microsoft JScript runtime error: Unable to get value of the property 'PRM_ParserErrorDetails': object is null or undefined

并发生在第行

this._endPostBack(this._createPageRequestManagerParserError(String.format(Sys.WebForms.Res.PRM_ParserErrorDetails,parserErrorDetails)),sender);

这些页面是使用母版页创建的，母版页包含UpdatePanel以及UpdateProgress控件。自更改为.net 2.0后，发生了此错误。当我更改它时，我将System.Web.Extensions程序集添加到Web.config，并从同一程序集注册控件。我在网上做过调查，似乎找不到有解决方案或类似问题的人。有什么建议或答案吗？

好的，像往常一样，我在发帖后几乎立即解决了这个问题。问题似乎是我的web.config文件中缺少了一些部分。我已使用注册控件
