Postsharp Methodboundry aspect not working with WCF Service class

Question

I have a custom aspect I am trying to add to my service to automatically log all error and send out an appropriate error message, but when I try to apply it on the class and set Attributetargetelements to Multicast.method or apply it to the individual method , my Service returns a 500 error with error message

Is there a way I can get around this?

My Code is as follows

Service Aspect

[Serializable]
public class ServiceAspect : OnMethodBoundaryAspect
{
    //create logger

    private static readonly log4net.ILog log = LogManager.GetLogger(typeof(BrokerServiceAspect).Name);//

    public override void OnException(MethodExecutionArgs args)
    {
        log.Error(args.Exception.Message, args.Exception);//log specific type of error
        args.FlowBehavior = FlowBehavior.Return;//return excution

        if (args.Exception is NullReferenceException)
        {
            args.ReturnValue = new FaultException(BrokerFaultCodes.NullExceptionCode);
        }
        else if (args.Exception is Exception)
        {
            args.ReturnValue = new FaultException(BrokerFaultCodes.GenericException);
        }
    }
}

And applying it on the class

[ServiceAspect(AttributeTargetElements = MulticastTargets.Method)]
[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any, InstanceContextMode = InstanceContextMode.PerCall,IncludeExceptionDetailInFaults = true)]
public class APIService : ServiceBase,IAPIService
{

as soon as I remove the service aspect from my code, it works as expected.

EDIT

Setting [OnMethodBoundaryAspectConfiguration(SerializerType = typeof(MsilAspectSerializer))] to replace the [Serializable attribute now returns

I have thought about that, but the issue is that the service does not start because of the [Serializable] attribute on the ServiceAspect. Changing the serializable attribute to [OnMethodBoundaryAspectConfiguration(SerializerType = typeof(MsilAspectSerializer))] returns Method not found: 'Void API.Model.Infrastructure.Aspect.ServiceAspect.OnException(PostSharp.Aspects.MethodExecutionArgs

Please have a look at this discussion. It seems you may have two different versions of PostSharp.dll in your project.
