You can implement an IHostedService by wiring a primary ServiceBusSessionProcessor with a paired DLQ processor, setting AutoCompleteMessages to false, and registering the typed ServiceBus client wrapper via dependency injection for clean testability.

Explicit message completion requires setting AutoCompleteMessages to false, ensuring your IHostedService manually completes messages after successful processing and applies clear error handling and logging for DLQ scenarios instead of relying on automatic completion.

The best way is using a ServiceBusSessionProcessor within an IHostedService pattern, which enables ordered message handling for sessionized messages while pairing a DLQ processor to manage failed message reprocessing.

Yes, you can register the Service Bus listener by using a typed ServiceBus client wrapper pattern within your DI container, which provides clean configuration and testability for your IHostedService implementation.

Failing to reprocess dead-letter messages often happens when the IHostedService lacks a paired DLQ processor; wiring a dedicated DLQ processor alongside the primary ServiceBusSessionProcessor resolves this missing reprocessing capability.

Yes, a paired DLQ processor is required for building resilient microservices that process sessionized Service Bus messages, ensuring failed messages are explicitly captured and reprocessed instead of being lost.
