Powerbuilder.Net WCF service - where is the Application_Start event

I am new to Powerbuilder.Net.

I am creating a WCF web service with Powerbuilder.Net 12.6 and I have a reference to the log4net.dll.

Normally in a C# project I would add a call to configure log4net ( XmlConfigurator.Configure() ) in the Application_Start event of the Global.asa.cs file.

I have tried to put code in the application object, Open event but this event does not appear to get called.

My log4net code works in the service operation (PB function) but I'd like to only do this configuration once at the start of the service.

Is there a PB.Net event that gets called at the start of the service?

Thanks,

...Herb
