ASP.NET：配置错误（“/”应用程序中的服务器错误。）
ASP.NET : Configuration Error(Server Error in '/' Application.)
这个错误让我抓狂！我正在处理我的 registration.aspx 页面，突然出现这个错误，我花了几天时间解决它，但没有任何效果！最后我删除了我的 registration.aspx 只是为了检查项目是否仍然在没有它的情况下工作但没有任何改变！
错误在第 15 行显示为红色：

请帮忙？
检查应用程序池，您似乎将其置于集成模式而不是经典模式。
<authentication> 不是 <pages> 的子级，它应该嵌套在 <system.web>
中
compilation和httpRuntime也需要移出
试试这个
<authentication mode="None"/>
<compilation debug="true" targetFramework="4.5"/>
<httpRuntime targetFramework="4.5"/>
<pages validateRequest="false">
<namespaces>
<add namespace="System.Web.Optimization"/>
<add namespace="Microsoft.AspNet.Identity"/>
</namespaces>
<controls>
<add assembly="Microsoft.AspNet.Web.Optimization.WebForms" namespace="Microsoft.AspNet.Web.Optimization.WebForms" tagPrefix="webopt"/>
</controls>
</pages>
您还有两个 compilation 属性。删除第二个。
该错误告诉您它无法识别 <pages> 下的 <authentication> 元素。那是因为<authentication>需要直接在<system.web>.
下
<configuration>
<system.web>
<authentication mode="None" /> <!-- This is the line that needed to be moved -->
<compilation debug="true" targetFramework="4.5"/>
<httpRuntime targetFramework="4.5"/>
