asp.net - 定义了重复的 'system.web.extensions/scripting/scriptResourceHandler' 部分

Question

我有 2 台服务器，我必须将网站迁移到一台 2003 年服务器到 2008 年服务器。当我尝试在 2008 服务器中运行该网站时，出现以下错误:定义了重复的 system.web.extensions/scripting/scriptResourceHandler 部分

但我在 web.config 中没有重复的“system.web.extensions/scripting/scriptResourceHandler”。当我删除这一行时，它会提示下一行重复，依此类推，直到我删除几乎所有配置部分。

Answer 1

当我尝试设置并运行的网站本应设置为在 .net 2.0/3.5 下运行时，我遇到了此问题，但我意外地将其设置为在 .NET 4.0 下运行。

背景:

原始问题下的每个评论“必须在某个地方有重复项，不一定在同一个 web.config 文件中。重复项可以位于不同文件夹级别的另一个 web.config 文件中，或者在某些情况下位于 machine.config 中”。我确实找到了重复的。在 .net 4.0 machine.config 中，存在重复我的 web.config 内容的条目，这导致了重复错误。但是，.net 2.0 machine.config 与我的 web.config 没有重复。

切换应用程序池以运行 .net 2.0(本应首先这样做)消除了错误。
