Managing ServiceBus queues, topics and subscriptions in .Net Core
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; } |
Using ManagementClient we can write much better code.
|
1 2 3 4 5 6 7 8 9 10 11 |
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
