.NET 3.5作为.NET 4.0在IIS7中的应用

Question

我在IIS7中遇到了一个阻止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。我得到了一个可怕的错误：

配置节'system.web.extensions‘无法读取，因为它缺少节声明

我尝试将父system.web中的整个web.config元素封装在location标记中，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，无论我尝试了什么，我都无法对子应用程序的行为进行任何更改。谁来帮帮忙。

编辑：

下面是整个web.config：

Answer 1

我认为您可以使用<remove />元素从父配置中删除元素。

或者仅仅使用<clear/>来清理整个部分

其实我只是自己试过。我没有遇到任何问题。我的环境如下。Win2008R2 +IS7.5

Site\AspNet4 4->用于asp.net 4应用程序

Site\AspNet4 4\AspNet4 35->用于Asp.net 3.5应用程序(这是一个虚拟文件夹)

我所做的就是把

 <location path="." inheritInChildApplications="false" allowOverride="true">
     <system.web>
        <compilation debug="true" targetFramework="4.0" />
     </system.web>
  </location>

我认为你的web.config有问题。

你为什么不发出来呢？
