SerilogWeb.Classic IIS classic mode incompatibility

[jsurville]

Hello,

I am using an app that was working fine with the IIS Classic Mode until I started using Serilog and SerilogWeb.Classic for logging.
Now that the application was deployed in Test environment, I get this exception :

[PlatformNotSupportedException: This operation requires IIS integrated pipeline mode..]
System.Web.HttpApplication.add_LogRequest(EventHandler value) +3674928
SerilogWeb.Classic.ApplicationLifecycleModule.Init(HttpApplication application) +159
System.Web.HttpApplication.InitModulesCommon() +170
System.Web.HttpApplication.InitModules() +71
System.Web.HttpApplication.InitInternal(HttpContext context, HttpApplicationState state, MethodInfo[] handlers) +824
System.Web.HttpApplicationFactory.GetNormalApplicationInstance(HttpContext context) +209
System.Web.HttpApplicationFactory.GetApplicationInstance(HttpContext context) +113
System.Web.HttpRuntime.ProcessRequestInternal(HttpWorkerRequest wr) +539

Is there any issue with using SerilogWeb.Classic in IIS Classic mode ? Because I cannot change the type of mode (I can change it on local environment but in test or production environment, the IIS pools are set to Classic mode and I can't have it changed)

Thank you for helping me,
Regars

Hi @jsurville
It's been a while since I've had to play with IIS .

Because the logging happens as part of the "LogRequest" event of the IIS pipeline

classic/src/SerilogWeb.Classic/Classic/ApplicationLifecycleModule.cs

Lines 255 to 258 in f07c97a

	application.LogRequest += (sender, args) =>
	{
	eventHandler.OnLogRequest(Config);
	};

I think this is only exposed in "Integrated mode" .

Long story short, if you can validate that your app works fine in "Integrated mode" , I guess you'd probably want to move it to Integrated mode as well in Test and Prod environments ?

My understanding is that "Classic Mode" is considered deprecated / legacy
