ASP.NET 4 / IIS HTTP錯誤

Question

我試圖在本地設置一個ASP.NET站點，當運行調試器時，代碼中沒有出現錯誤，但是當我轉到該站點時，看到以下內容：

HTTP Error 500.19 - Internal Server Error The 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

我如何解決此問題，我相信這是一個IIS問題，但是我研究的所有內容尚不清楚如何解決此問題。

Answer 1

您確定在應用程序池中設置了正確的框架版本嗎？ 在低於.NET 4.0的任何版本中，都無法識別System.web.extensions。

Answer 2

我認為這與web.config中的配置部分有關。 您需要在

                 <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"/>

                            <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>

                            <section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>
