我在 IIS (7.5) 中托管一个 Web API 作为 下的应用程序"Default Web Site"，并且正在使用来自 Serilog.Extras.Web 的几个 Enrichers（我将很快升级到 SerilogWeb.Classic 包）。我注意到在我的日志中每个请求ApplicationLifecycleModule.LogRequest()都被调用了两次，我试图理解为什么。
我注意到它ApplicationLifecycleModule.Init()被调用了两次，因此注册了两个事件处理程序。
第一个调用栈：
Serilog.Extras.Web.dll!Serilog.Extras.Web.ApplicationLifecycleModule.Init(System.Web.HttpApplication context)
System.Web.dll!System.Web.HttpApplication.RegisterEventSubscriptionsWithIIS(System.IntPtr appContext, System.Web.HttpContext context, System.Reflection.MethodInfo[] handlers)
System.Web.dll!System.Web.HttpApplication.InitSpecial(System.Web.HttpApplicationState state, System.Reflection.MethodInfo[] handlers, System.IntPtr appContext, System.Web.HttpContext context)
System.Web.dll!System.Web.HttpApplicationFactory.GetSpecialApplicationInstance(System.IntPtr appContext, System.Web.HttpContext context)
System.Web.dll!System.Web.Hosting.PipelineRuntime.InitializeApplication(System.IntPtr appContext)
[AppDomain Transition]
第二个：
Serilog.Extras.Web.dll!Serilog.Extras.Web.ApplicationLifecycleModule.Init(System.Web.HttpApplication context)
System.Web.dll!System.Web.HttpApplication.InitModulesCommon()
System.Web.dll!System.Web.HttpApplication.InitInternal(System.Web.HttpContext context, System.Web.HttpApplicationState state, System.Reflection.MethodInfo[] handlers)
System.Web.dll!System.Web.HttpApplicationFactory.GetNormalApplicationInstance(System.Web.HttpContext context)
System.Web.dll!System.Web.HttpApplicationFactory.GetApplicationInstance(System.Web.HttpContext context)
System.Web.dll!System.Web.HttpRuntime.ProcessRequestNotificationPrivate(System.Web.Hosting.IIS7WorkerRequest wr, System.Web.HttpContext context)
System.Web.dll!System.Web.Hosting.PipelineRuntime.ProcessRequestNotificationHelper(System.IntPtr rootedObjectsPointer, System.IntPtr nativeRequestContext, System.IntPtr moduleData, int flags)
System.Web.dll!System.Web.Hosting.PipelineRuntime.ProcessRequestNotification(System.IntPtr rootedObjectsPointer, System.IntPtr nativeRequestContext, System.IntPtr moduleData, int flags)
难道我做错了什么？或者这是一个错误ApplicationLifecycleModule？
