OrderService — In-Process Dead-Letter Replay

Location: samples/deadletter-inproc/OrderService.InProcDeadLetter/
Transport: In-memory sample channels
Pattern: Dead-letter callback + immediate replay through the publisher pipeline

What it demonstrates​

  • a failing publish channel that simulates a broken transport
  • AddDeadLetter(...).UseHandler(...) for in-process dead-letter interception
  • replaying the captured CloudEvent back through IEventPublisher
  • targeting a recovery channel with DeadLetterReplayPublishOptions

Flow​

The replay stays inside the same process and uses the same publisher pipeline. The replay marker prevents the replay attempt from being captured as a new dead-letter record.

Run it​

cd samples/deadletter-inproc/OrderService.InProcDeadLetter
