Managing ServiceBus queues, topics and subscriptions in .Net Core

October 22, 2018October 22, 2018 Leave a comment

From version 3.1 of Microsoft.Azure.ServiceBus it is finally possible to manage queues, topics and subscriptions in .Net Core. Let’s have a look at how we can use it in real life scenarios. Previously we would use sample code for getting a queue:

public IQueueClient GetQueueClient(string _serviceBusConnectionString, string _queueName)
{
    var queueClient = new QueueClient(_serviceBusConnectionString, _queueName);
    return queueClient;
}

public IQueueClient GetQueueClient(string _serviceBusConnectionString, string _queueName)

{

var queueClient = new QueueClient(_serviceBusConnectionString, _queueName);

return queueClient;

}

Using ManagementClient we can write much better code.

public async Task<IQueueClient> GetOrCreateQueue(string _serviceBusConnectionString, string _queueName)
{
    var managementClient = new ManagementClient(_serviceBusConnectionString);
    if (!(await managementClient.QueueExistsAsync(_queueName)))
    {
        await managementClient.CreateQueueAsync(new QueueDescription(_queueName));
    }

    var queueClient = new QueueClient(_serviceBusConnectionString, _queueName);
    return queueClient;
}

public async Task<IQueueClient> GetOrCreateQueue(string _serviceBusConnectionString, string _queueName)

{

var managementClient = new ManagementClient(_serviceBusConnectionString);

if (!(await managementClient.QueueExistsAsync(_queueName)))

{

await managementClient.CreateQueueAsync(new QueueDescription(_queueName));

}

var queueClient = new QueueClient(_serviceBusConnectionString, _queueName);

return queueClient;

}

Now before getting a… Continue reading Managing ServiceBus queues, topics and subscriptions in .Net Core
