Is possible to integrate elmah with wf-wcf services using web.config?

Question

Hi, i'm developing an enterprise application using asp.net mvc, wf-wcf services and normal wcf. I want use a unique point of view of unmanaged exception and my problem is integrate wf-wcf services with ELMAH. The problem is that in wf-wcf i can't decorate di class with the elmah attribute so i make that using web.config if is possible. Someone can help me? (here is a discussion how integrate elmah with wcf using attribute http://stackoverflow.com/questions/895901/exception-logging-for-wcf-services-using-elmah)

thanks in advance F.

Interesting, hadn't thought of that before, as ELMAH is an awesome addon for websites.

The same approach should work for WF services. The way to add the ServiceErrorBehaviourAttribute in the config file is by using a BehaviorExtensionElement. The following code should do the trick

public class ServiceErrorBehaviourElement : BehaviorExtensionElement {
    public override Type BehaviorType {
        get { return typeof(ServiceErrorBehaviourAttribute); }
    }

    protected override object CreateBehavior() {
        return new ServiceErrorBehaviourAttribute();
    }
}

Register the type to the behaviorExtensions and you can the behavior to your workflow service serviceBehaviors element.
