Attaching to FirstBeginRequest should be avoided


Hi, im working on a projekt where this appears frequently in the log-files

WARN EPiServer.Web.InitializationModule[(null)] - Attaching to FirstBeginRequest should be avoided. Rewrite your code to implement an IInitializableModule instead

I cant find any references to FirstBeginRequest in our code.

Can anyone shed some light on this? Would it be safe to ignore this and only log erorrs from InitializationModule?

Some code somewhere is attaching to this event. Have you added any plug-ins from Nuget, EPiCode etc that you don't have the source code for and therefore don't see the call when you search?

Thanks for your reply.

These are the only references I can find when reflecting. All of them are from EPiServer code.

  • EPiServer.MirroringService.MirroringMonitoring.MirroringMonitoringModule.Init
  • EPiServer.Scheduler.Initializer.Init
  • EPiServer.WorkflowFoundation.WorkflowSystem.Init
