What's the equivalent of NamespaceManager.GetQueue.MessageCount in the new NET Standard Microsoft.Azure.ServiceBus?

Question

What's the equivalent of NamespaceManager in the new NET Standard Microsoft.Azure.ServiceBus?

I've used WindowsAzure.ServiceBus to do things like count messages in a queue ...

var namespaceManager = NamespaceManager.CreateFromConnectionString(SbConnectionString);
var count = namespaceManager.GetQueue(queueName).MessageCount;

Moving over to the new Microsoft.Azure.ServiceBus .NET Standard library, but whilst it's got classes like QueueClient and TopicClient, it's not got any NamespaceManager

How can you could do message counts in the new .NET Standard library?

Answer 1

You can't.

The new API doesn't support reading message counts. You'd have to use Azure Monitor API to get them.

Read why that's that case and how to work with Azure Monitor in Reading Azure Service Bus Metrics.

Answer 2

To provide an update:

This is now implemented and available under the Microsoft.Azure.ServiceBus.Management; namespace.

NamespaceManager is now called ManagementClient and has (roughly) the same endpoints available.

Here's the class itself as part of the pull request to merge it into the main repository.
