Azure Service Bus Error. Send message to Queue - The X.509 certificate CN=servicebus.windows.net chain building failed

Hi,

I am trying to complete this tutorial:

Service Bus Brokered Messaging .NET Tutorial

This is a simple tutorial, where you:

- manually create a Service Bus Namespace using the Azure portal ,
- programatically create a queue,
- programatically send to the queue,
- programatically read from the queue

I have copied the final code that is run inside my own console application from:
Shows Complete Code to run

And tried to run, The Queue is successfully created on the Azure portal with the below code:

     NamespaceManager namespaceClient = new NamespaceManager(ServiceBusEnvironment.CreateServiceUri("sb", ServiceNamespace, string.Empty), credentials);
     namespaceClient.CreateQueue("IssueTrackingQueue");

 

But when trying to Send to the Queue using this abridged code (complete code can be seen in link above):

 

   QueueClient myQueueClient = factory.CreateQueueClient("IssueTrackingQueue");
            // Send messages
            Console.WriteLine("Now sending messages to the Queue.");
            for (int count = 0; count < 6; count++)
            {
                var issue = MessageList[count];
                issue.Label = issue.Properties["IssueTitle"].ToString();
                myQueueClient.Send(issue);
                Console.WriteLine(string.Format("Message sent: {0}, {1}", issue.Label, issue.MessageId));
            }

The below code throws error:

 myQueueClient.Send(issue);
Error as below:
Message=The X.509 certificate CN=servicebus.windows.net is not in the trusted people store. The X.509 certificate CN=servicebus.windows.net chain building failed. The certificate that was used has a trust chain that cannot be verified. Replace the certificate or change the certificateValidationMode. A certificate chain could not be built to a trusted root authority.

I have seen references to this error using the On-Premise Windows Service Bus, but not with the Azure Service Bus, as this example uses.

I am using the Azure SDK 2.2
It takes approx 10 - 20 seconds before get error, 

The full error is as below:
