Je reçois OperationCanceledException lorsque j'envoie un message à une file d'attente de sujets (j'exécute mon code depuis une fonction Azure). La version que j'utilise est: "WindowsAzure.ServiceBus": "4.1.1" (le plus récent) et je reçois cette exception quand je fais le test de charge qui signifie que beaucoup de messages sont envoyés dans ce bus de service (qui contient plusieurs les sujets). On m'a dit d'utiliser un mécanisme de nouvelle tentative comme:OperationCanceledException lors de l'envoi au Service Bus
client.RetryPolicy = new RetryExponential(minBackoff: TimeSpan.FromSeconds(0.1),
maxBackoff: TimeSpan.FromSeconds(30),
maxRetryCount: 3);
Mais je pensais que cela est déjà fait par défaut, non?
Conviendrait votre aide ici - Pourquoi ai-je cette exception et que puis-je faire pour résoudre ce problème?
Voici l'exception:
Exception System.OperationCanceledException: The operation cannot be performed because the entity has been closed or aborted. ---> System.ServiceModel.CommunicationObjectAbortedException: Internal Server Error: The server did not provide a meaningful reply; this might be caused by a premature session shutdown.
