Sending and Receving messages to Azure Service Bus using ASP.NET framework 4.8

Thanks for posting your question in the Microsoft Q&A forum.

Here's an example of how you can send and receive messages:

1. Install the Azure.Messaging.ServiceBus NuGet package in your ASP.NET Core project.
2. In your Startup.cs file, add the following code to register the ServiceBusClient as a singleton service:

      public void ConfigureServices(IServiceCollection services)
      {
          services.AddSingleton(serviceProvider =>
          {
              var connectionString = Configuration.GetConnectionString("ServiceBusConnectionString");
              return new ServiceBusClient(connectionString);
          });
      }
      
   

3. Create a new class, for example, ServiceBusQueueService.cs, and implement the logic for sending and receiving messages:

      using Azure.Messaging.ServiceBus;
      public class ServiceBusQueueService
      {
          private readonly ServiceBusClient _serviceBusClient;
          private readonly string _queueName = "myqueue"; 
          public ServiceBusQueueService(ServiceBusClient serviceBusClient)
          {
              _serviceBusClient = serviceBusClient;
          }
          public async Task SendMessageAsync(string message)
          {
              var sender = _serviceBusClient.CreateSender(_queueName);
              var serviceBusMessage = new ServiceBusMessage(message);
              await sender.SendMessageAsync(serviceBusMessage);
          }
          public async Task ReceiveMessagesAsync()
          {
              var receiver = _serviceBusClient.CreateReceiver(_queueName);
              var messages = await receiver.ReceiveMessagesAsync(maxMessages: 10);
              foreach (var message in messages)
              {
                  Console.WriteLine($"Received message: {message.Body}");
                  await receiver.CompleteMessageAsync(message);
              }
          }
      }
      
   

4. In your controller or service where you want to send or receive messages, inject the ServiceBusQueueService and call the respective methods:

public class MyController : Controller
{
    private readonly ServiceBusQueueService _serviceBusQueueService;
    public MyController(ServiceBusQueueService serviceBusQueueService)
    {
        _serviceBusQueueService = serviceBusQueueService;
    }
    public async Task<IActionResult> SendMessage(string message)
    {
        await _serviceBusQueueService.SendMessageAsync(message);
        return Ok();
    }
    public async Task<IActionResult> ReceiveMessages()
    {
        await _serviceBusQueueService.ReceiveMessagesAsync();
        return Ok();
    }
}
