System.InvalidOperationException：失败，错误代码为0xe＆＃34; at＆＃34; Microsoft.ServiceBus.Tracing.EventProviderClone.Register＆＃34;

Question

在Azure中运行我的客户端代码时，我遇到了这个异常：

System.InvalidOperationException: Failed with error code 0xe.

我使用的是WIndowsAzure.ServiceBus v3.4.6软件包。

我创建客户端的代码是这样的：

    private QueueClient QueueClient(string queueName)
    {
        var namespaceManager = NamespaceManager.CreateFromConnectionString(_serviceBusEndPoint);

        namespaceManager.Settings.RetryPolicy = new RetryExponential(
            minBackoff: TimeSpan.FromSeconds(0),
            maxBackoff: TimeSpan.FromSeconds(30),
            maxRetryCount: 5);

        var messagingFactory = MessagingFactory.Create(namespaceManager.Address, namespaceManager.Settings.TokenProvider);

        messagingFactory.RetryPolicy = new RetryExponential(
            minBackoff: TimeSpan.FromSeconds(1),
            maxBackoff: TimeSpan.FromSeconds(30),
            maxRetryCount: 5);

        var client = messagingFactory.CreateQueueClient(queueName);

        client.RetryPolicy =
            new RetryExponential(
                minBackoff: TimeSpan.FromSeconds(0.1),
                maxBackoff: TimeSpan.FromSeconds(30),
                maxRetryCount: 5);

        return client;
    }

我对这个例外发生的原因感到茫然。
