c# - 如何从 ASP.NET 4.0 Web 应用程序中禁用/删除 WebPageHttpModule？

Question

我正在尝试获取我的 wildcard http handler to handle *.cshtml pages但是请求永远不会到达我的处理程序，因为它看起来像是被 WebPageHttpModule 拦截了，我发现它是通过这个 StackTrace 存在的:

[HttpException (0x80004005): Exception of type 'System.Web.HttpException' was thrown.]
   System.Web.WebPages.ApplicationStartPage.ExecuteStartPage(HttpApplication application, Action`1 monitorFile, Func`2 fileExists, Func`2 createInstance, IEnumerable`1 supportedExtensions) +88
   System.Web.WebPages.ApplicationStartPage.ExecuteStartPage(HttpApplication application) +287
   System.Web.WebPages.WebPageHttpModule.StartApplication(HttpApplication application, Action`1 executeStartPage, EventHandler applicationStart) +113
   System.Web.WebPages.WebPageHttpModule.StartApplication(HttpApplication application) +71
   System.Web.WebPages.WebPageHttpModule.Init(HttpApplication application) +156
   System.Web.HttpApplication.RegisterEventSubscriptionsWithIIS(IntPtr appContext, HttpContext context, MethodInfo[] handlers) +431
   System.Web.HttpApplication.InitSpecial(HttpApplicationState state, MethodInfo[] handlers, IntPtr appContext, HttpContext context) +194
   System.Web.HttpApplicationFactory.GetSpecialApplicationInstance(IntPtr appContext, HttpContext context) +339
   System.Web.Hosting.PipelineRuntime.InitializeApplication(IntPtr appContext) +253

[HttpException (0x80004005): Exception of type 'System.Web.HttpException' was thrown.]
   System.Web.HttpRuntime.FirstRequestInit(HttpContext context) +8972180
   System.Web.HttpRuntime.EnsureFirstRequestInit(HttpContext context) +97
   System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +256

我尝试使用 Web.Config 禁用所有 HttpModules 但这没有效果，(它也没有出现在 IIS HttpModules 部分):

<system.web>
    <httpModules>
        <clear/>
    </httpModules>
</system.web>
    ....
<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
        <clear/>
    </modules>
</system.webServer>

使用 ILSpy 寻找 System.Web.WebPages.dll 中的以下代码是注册 WebPageHttpModule 的代码:

namespace System.Web.WebPages
{
    [EditorBrowsable(EditorBrowsableState.Never)]
    public static class PreApplicationStartCode
    {
        private static bool _startWasCalled;
        public static void Start()
        {
            if (PreApplicationStartCode._startWasCalled)
            {
                return;
            }
            PreApplicationStartCode._startWasCalled = true;
            WebPageHttpHandler.RegisterExtension("cshtml");
            WebPageHttpHandler.RegisterExtension("vbhtml");
            PageParser.EnableLongStringsAsResources = false;
            DynamicModuleUtility.RegisterModule(typeof(WebPageHttpModule));
            ScopeStorage.CurrentProvider = new AspNetRequestScopeStorageProvider();
        }
    }
}

但它是一个 vanilla .NET 4.0 应用程序，我没有对任何 System.Web.WebPages、MVC 或 Razor dll 的引用我仅引用System.Web.

那么这些程序集是如何加载的，为什么要注册 WebPageHttpModule 以及如何删除/禁用它？

如果您尝试关闭 ASP.NET 网页，您可以在应用程序设置中设置此标志:

<add key="webpages:Enabled" value="false" />
