Debugging with single thread Azure QueueTrigger

Is there any way I can debug a queuetrigger without the multiple threading? I got several messages in the queue and my program keeps junping back and forth everytime I press contitnue or press forward, it makes it very hard to keep track of things.

I've tried to add IsBatched = false as run parameter and changing the host file to have "maxConcurrentCalls": 1 but nothing works. I'm using Visual Studio

  [Function("ProcessSensorWarningMessages")]
  public void Run(
      [ServiceBusTrigger("sensor_warningmessagedata", Connection = "ServiceBus-ConnetionString",IsBatched = false)]
      ServiceBusReceivedMessage message,
      ServiceBusMessageActions messageActions)
  {
     
     
      try
      {
          _logger.LogInformation("Message ID: {id}", message.MessageId);
          _logger.LogInformation("Message Body: {body}", message.Body);
          _logger.LogInformation("Message Content-Type: {contentType}", message.ContentType);

          SmsServiceTemp smsService = new SmsServiceTemp(_logger);
          EmailServiceTemp emailService = new EmailServiceTemp(_logger);
          EnviromentVariables.EnviromentConfig(_logger);// fix so program crashes if null
          string messageBody = message.Body.ToString(); // change program to use mesage body i dont need controller class here 
          SensorDatabaseQueryTemp sensorDatabaseQueryTemp = new SensorDatabaseQueryTemp(_logger);
          SensorDatabaseQueryLastSeen sensorDatabaseQueryLastSeen = new SensorDatabaseQueryLastSeen(_logger);
          SensorDataQueueModel queueData = JsonSerializer.Deserialize<SensorDataQueueModel>(messageBody);
          if (queueData.TempId > 0)
          {

              JoinedSensorDataTemp temp = sensorDatabaseQueryTemp.GetJoinedSensorData(queueData.TempId);
              SmsEmailHelperTemp.Warningloop(temp, _logger);
              _logger.LogInformation("Successfully sendt Warning");
              messageActions.CompleteMessageAsync(message);
          }
          else if (queueData.LastSeenId > 0)
          {
              JoinedSensorDataTemp lastSeen = sensorDatabaseQueryLastSeen.GetJoinedSensorData(queueData.LastSeenId);
              SmsEmailHelperLastSeen.Warningloop(lastSeen, _logger);
              _logger.LogInformation("Successfully sendt Warning");
              messageActions.CompleteMessageAsync(message);

          }
          else
          {
              //null exception
          }

      }
      catch (JsonException ex)
      {
          _logger.LogError(ex, "Error deserializing message body.");
          messageActions.DeadLetterMessageAsync(message);
      }
      // Complete the message
  }

Solution

Debugging with single thread Azure QueueTrigger. Is there any way I can debug a queuetrigger without the multiple threading?

Below code and configuration settings works for me and I followedMicrosoft-Document and SO-Thread:

local.settings.json:

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_INPROC_NET8_ENABLED": "1",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "AzureFunctionsJobHost__extensions__serviceBus__messageHandlerOptions__maxConcurrentCalls": "1",
    "rithcon": "Endpoint=sb://rith02.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=o+25LyrithwikBCHtucjOrithwikhA="
  }
}

Fuction.cs:

using System.Threading.Tasks;
using Azure.Messaging.ServiceBus;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.ServiceBus;
using Microsoft.Extensions.Logging;

namespace RithApp
{
    public class Function1
    {
        [FunctionName("Function1")]
        public async Task Run(
            [ServiceBusTrigger("rithq", Connection = "rithcon", IsSessionsEnabled = false)] ServiceBusReceivedMessage rith, ServiceBusMessageActions messageActions, ILogger ri_lg)
        {
            ri_lg.LogInformation($"Hello Rithwik, Message is: {rith.Body}");
            var messageBody = rith.Body.ToString();
            await messageActions.CompleteMessageAsync(rith);
            ri_lg.LogInformation("Message has been processed Rithwik.");

        }
    }
}

host.json:

{
  "version": "2.0",
  "extensions": {
    "serviceBus": {
      "messageHandlerOptions": {
        "maxConcurrentCalls": 1,
        "autoComplete": false
      }
    }
  },
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      },
      "enableLiveMetricsFilters": true
    }
  }
}

Output:
