C# Class EasyNetQ.Consumer.DefaultConsumerErrorStrategy

A strategy for dealing with failed messages. When a message consumer thows, HandleConsumerError is invoked. The general priciple is to put all failed messages in a dedicated error queue so that they can be examined and retried (or ignored). Each failed message is wrapped in a special system message, 'Error' and routed by a special exchange named after the orignal message's routing key. This is so that ad-hoc queues can be attached for errors on specific message types. Each exchange is bound to the central EasyNetQ error queue.
