我已经尝试使用Web.Config禁用所有HttpModules,但这没有任何效果(它也不会出现在IIS HttpModules部分)：

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

用ILSpy狩猎显示System.Web.WebPages.dll中的以下代码是注册WebPageHttpModule的内容：

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();
        }
    }
}

但是它是一个香草.NET 4.0应用程序,我没有引用任何System.Web.WebPages,MVC或Razor dll我只是引用System.Web.

那么这些程序集如何加载,为什么WebPageHttpModule被注册了,我该如何删除/禁用它？
