.net - デバイスからクラウドへのメッセージを受信する IoT ハブでのエラー

Question

(C# を使用して) Azure Web サイトから iothub デモを実行すると、次のように常に例外が発生します。

Microsoft.ServiceBus.Messaging.MessagingCommunicationException was unhandled

これはInnerExceptionです:

            eventHubClient = EventHubClient.CreateFromConnectionString(connectionString, iotHubD2cEndpoint);

        var d2cPartitions = eventHubClient.GetRuntimeInformation().PartitionIds;  //////this place occured exception

        CancellationTokenSource cts = new CancellationTokenSource();

        };

        var tasks = new List<Task>();
        foreach (string partition in d2cPartitions)
        {
            tasks.Add(ReceiveMessagesFromDeviceAsync(partition, cts.Token));
        }
        Task.WaitAll(tasks.ToArray());
    }
    private static async Task ReceiveMessagesFromDeviceAsync(string partition, CancellationToken ct)
    {
        var eventHubReceiver = eventHubClient.GetDefaultConsumerGroup().CreateReceiver(partition, DateTime.UtcNow);
        while (true)
        {
            if (ct.IsCancellationRequested) break;
            EventData eventData = await eventHubReceiver.ReceiveAsync();
            if (eventData == null) continue;

            string data = Encoding.UTF8.GetString(eventData.GetBytes());
            Console.WriteLine("Message received. Partition: {0} Data: '{1}'", partition, data);
        }
    }
}
}

私のプロジェクトで何が問題なのか誰にも分かりませんか? どうもありがとう。NuGetパッケージの最新バージョンを使用していて、Event Hub作成できたのですが、次のときにエラーが発生しました。

var d2cPartitions = eventHubClient.GetRuntimeInformation().PartitionIds
