Creating Evenhub topic with EventHubManagementClient

Question

I'm trying to create an EventHub topic within a namespace through my .net core application. I'm a bit struggling with the authentication and couldn't figure out exactly what should I do to get the Token credentials from Azure.

Should I use ConfidentialClientApplicationBuilder? and if yes how exactly I give access to the specific EventHub namespace and get all the data required (clientId, clientSecret, Authorithy and TenantId)?

Thanks ahead.

microsoft.Identity.client, azure.resourcemanager.eventhub and microsoft.azure.management.eventhub — Tubul, Aug 07 '22 at 17:28
The answer will differ greatly between the current management library (Azure.ResourceManager.EventHubs) and the legacy library (which is deprecated and not recommended). — Jesse Squire, Aug 08 '22 at 13:21

Given that the legacy package is deprecated and not recommended, this is based on use of the current generation management package, Azure.ResourceManager.EventHubs.

There is no need to work with Microsoft.Identity.Client or any of the related types; the auth story for the current generation has been simplified to work directly with Azure.Identity token types that manage token acquisition implicitly.

There's a full sample here, but the important parts are:

// Create your client
ArmClient armClient = new ArmClient(new DefaultAzureCredential());

// Get the subscription
SubscriptionResource subscription = await armClient.GetDefaultSubscriptionAsync();

// Get the resource group
ResourceGroupResource resourceGroup = await subscription.GetResourceGroupAsync("myRg");

// Get your Event Hubs namespace
EventHubsNamespaceCollection namespaceCollection = resourceGroup.GetEventHubsNamespaces();
EventHubsNamespaceResource eventHubNamespace = await namespaceCollection.GetAsync("myNamespace");

// Create your Event Hub
EventHubResource eventHub = 
    (await eventHubCollection.CreateOrUpdateAsync(
        WaitUntil.Completed, 
        "myEventhub", 
        new EventHubData())
    ).Value;

More information on using Azure.Identity to authenticate can be found in the Overview docs.
