Receiving only one message from Azure Service Bus

Some time ago I got a question from Eto: “How would I go about this if I just want to receive one message only?” And I started thinking… is it possible in .Net Core?

I used the newest Microsoft.Azure.ServiceBus package, that is dedicated for .Net Core, but there is no method to receive only one message. So I used regular RegisterMessageHandler with a twist:

As you can see it is a standard approach, but after successfully processed message, I close queueClient. This works and it receives only one message, but it also gives an error.

I wasn’t fully satisfied with the solution, so I asked a question on StackOverflow: https://stackoverflow.com/questions/50438466/azure-service-bus-in-net-core-how-to-receive-only-one-message

After a few hours, I got an answer, that it is possible and I should just… use different package!

Using the old package

So far I didn’t manage to use old package in .NetCore project. So in order to install package WindowsAzure.ServiceBus, you need to have project referencing full framework.

And here is the code:

So that’s it and it works, but sadly not in .Net Core. However, I’ll keep this post up to date when such thing will be possible.
