A long-running handler exceeds the lock duration and the message is redelivered. What is the correct fix?
- A Set LockDuration to 30 minutes
- B Periodically call RenewMessageLockAsync while processing (correct answer)
- C Switch to receive-and-delete
- D Disable dead-lettering
Shortcut: LockDuration is capped at 5 minutes. Renewing the lock during processing (or offloading the work and completing quickly) is the supported approach.
