# How to Process Azure Service Bus Messages in ASP.NET Core Background Services?

Azure Service Bus enables enterprise messaging between distributed components. In ASP.NET Core, message consumption can be handled continuously using hosted background services.

## Setting Up Azure.Messaging.ServiceBus

Install the official `Azure.Messaging.ServiceBus` library to handle queues and topic subscriptions.

## Creating a Custom Hosted Background Service

Inherit from `BackgroundService` and manage the lifecycle of `ServiceBusProcessor`:

```cs
using Azure.Messaging.ServiceBus;
using Microsoft.Extensions.Hosting;

public class QueueConsumerService : BackgroundService
{
    private readonly ServiceBusProcessor _processor;

    public QueueConsumerService(ServiceBusClient client)
    {
        _processor = client.CreateProcessor("my-queue", new ServiceBusProcessorOptions());
    }

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        _processor.ProcessMessageAsync += MessageHandler;
        _processor.ProcessErrorAsync += ErrorHandler;

        await _processor.StartProcessingAsync(stoppingToken);
    }

    private async Task MessageHandler(ProcessMessageEventArgs args)
    {
        string body = args.Message.Body.ToString();
        await args.CompleteMessageAsync(args.Message);
    }

    private Task ErrorHandler(ProcessErrorEventArgs args)
    {
        return Task.CompletedTask;
    }
}
```
