ASP.NET 4 / IIS HTTP Error

本文关键字：HTTP Error IIS NET ASP | 更新日期: 2023-09-27 17:57:34

我正在尝试在本地设置ASP.NET站点。当我运行调试器时，我在代码中没有错误，但当我转到该站点时，我看到以下内容：

HTTP Error 500.19 - Internal Server ErrorThe requested page cannot be accessed because the related configuration data for the page is invalid.Module IIS Web Core Notification Unknown Handler Not yet determined Error Code 0x80070032 Config Error The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration Config File ''?'C:'SecondCity'Website'web.config Requested URL http://localhost:80/ Physical Path
Logon Method Not yet determined Logon User Not yet determined

我该如何解决这个问题，我相信这是一个IIS问题，但我所研究的一切都不清楚如何解决。

您确定在应用程序池中设置了正确的框架版本吗？在低于.NET 4.0的任何版本中都无法识别System.web.extensions。

我认为它与web.config中的配置节有关。您需要在中添加如下所示的节组

                 <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>
                         <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
                            <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="Everywhere"/>
                         <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>
