我遇到了阻止IIS 7中的web.config继承的问题。我有一个.NET 3.5应用程序，它是IIS 7中.NET 4.0应用程序的子应用程序。我收到了可怕的错误：
无法读取配置部分'system.web.extensions'，因为它缺少部分声明
我试图将整个system.web元素包装在位置标记中的父web.config中，其中inheritInChildApplications设置为false，allowOverRide设置为true，如下所示：
<location path="." inheritInChildApplications="false" allowOverRide="true">
<system.web>
.....
</system.web>
然而，无论我尝试过什么，我都无法对子应用程序的行为进行任何改变。有人请帮忙。
编辑：
这是整个web.config：

答案 0 :(得分：0)
我认为您可以使用<remove />元素从父配置中删除元素。
或者只使用<clear/>来清理整个部分
其实我只是自己尝试过。我没有遇到任何问题。 我的环境如下。 Win2008R2 + IIS7.5
网站\ AspNet4 - ＆gt; for asp.net 4 application
网站\ AspNet4 \ AspNet35 - ＆gt;对于Asp.net 3.5应用程序（这是一个虚拟文件夹）
我所做的只是放
<location path="." inheritInChildApplications="false" allowOverride="true">
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
</location>
我认为你的web.config中有问题。
你为什么不发布它？
