Приведенный ниже код активирует повтор 2-го уровня и IErrorHandler.
Проблема в том, что IErrorHandler никогда не вызывается .
var activator = new BuiltinHandlerActivator();
activator.Register((bus, mc) => new Handler(mc, bus));
Configure.With(activator)
.Transport(t => t.UseAzureServiceBus(Consts.ServiceBusConnectionString, Consts.Subscriber1))
.Options(o =>
{
o.SimpleRetryStrategy(maxDeliveryAttempts: 2,
secondLevelRetriesEnabled: true,
errorQueueAddress: "poison");
o.Decorate<IErrorHandler>(c => new MyErrorHandler(c.Get<IErrorHandler>()));
}).Start();

class Handler : IHandleMessages<string>,
IHandleMessages<IFailed<object>>
{
readonly IBus _bus;
readonly IMessageContext _messageContext;
public Handler(IMessageContext messageContext, IBus bus)
{
_messageContext = messageContext;
_bus = bus;
}
public async Task Handle(string message)
{
Console.WriteLine("Handle(string message): {0}", message);
throw new Exception("Handle(string message)");
}
public async Task Handle(IFailed<Object> message)
{
Console.WriteLine("Handle(IFailed<Object> message): {0}", message);
await _bus.Advanced.TransportMessage.Defer(TimeSpan.FromSeconds(2));
}
}
В частности, ниже приведена последовательность запуска повторных попыток 1-го и 2-го уровня:
Последовательности вызова на основе maxDeliveryAttempts2:
1 вызов Handle (строковое сообщение), исключение в Handle (строковое сообщение)
2 вызов Handle (строковое сообщение), исключение в Handle (строковое сообщение)
3 вызывающего дескриптора (сообщение IFailed)
4 вызывающего дескриптора (сообщение IFailed)
5 вызывающего дескриптора (сообщение строки), исключение в пределах дескриптора (сообщение строки)
6 вызывающий дескриптор (сообщение IFailed)
Повтор 5 и 6 навсегда
Вопрос A:
Почему IErrorHandler не вызывается?
Как вызывать IErrorHandler после вызова Handle (сообщение IFailed) 2 раза на основе maxDeliveryAttempts, равного 2.
То есть:
Вызов последовательностей на основе maxDeliveryAttempts равен 2:
1 вызывающий дескриптор (строковое сообщение), сгенерировать исключение в дескрипторе (строковое сообщение)
2 вызывающий дескриптор (строковое сообщение) сгенерировать исключение в дескрипторе (строковое сообщение)
3 вызывающий дескриптор(Сообщение IFailed)
4, вызывающий дескриптор (сообщение IFailed)
5, вызывающий IErrorHandler

Обновление
Та же проблема возникает на IHandleMessages<IFailed<string>>.
