this assembly is in my publisher that is separate application

"Exception":"System.IO.FileNotFoundException: Could not load file or assembly 'OAuth.Admin.Infrastructures.RabbitMQEventBus, Culture=neutral, PublicKeyToken=null'.

Answer 1

the problem is that my consumer couldn't deserialize messages i use this code in my Consumer and my problem is fixed

protected override Task ExecuteAsync(CancellationToken stoppingToken)
    {
        stoppingToken.ThrowIfCancellationRequested();

        var consumer = new EventingBasicConsumer(_channel);

        consumer.Received += HandleMessageAsync; ;

        _channel.BasicConsume("BlaBlaBlaQueue", false, consumer);
        return Task.CompletedTask;
    }

    private async void HandleMessageAsync(object sender, BasicDeliverEventArgs e)
    {
        var content = System.Text.Encoding.UTF8.GetString(e.Body);
        ConfirmRequest confirmRequest  = JsonConvert.DeserializeObject<ConfirmRequest>(content);

        var result =await sendConfirmBlaBlaBlaResuest.ConfirmBlaBlaBlaAsync(new BlaBlaBlaDto {});
        var responce = new ConfirmBlaBlaBlaResponceEvent(confirmRequest);

        if (result.IsFailure)
        {
            responce.Message = result.Error;
            responce.IsSuccess = false;
        }
        else
        {
            responce.IsSuccess = true;
        }

        await bus.PublishBlaBlaBlaResponceEventAsync(responce);
        _channel.BasicAck(e.DeliveryTag, false);
    }

and my producer is

public async Task PublishBlaBlaBlaEventAsync(BlaBlaBlaEvent myEvent)
    {
        var exchange = _bus.ExchangeDeclare(rabbitOptions.BlaBlaBlaExchangeName, ExchangeType.Topic);
        var queue = _bus.QueueDeclare(rabbitOptions.BlaBlaBlaQueueName);
        _bus.Bind(exchange, queue, "#");
        var message = new Message<BlaBlaBlaEvent>(myEvent);
        await _bus.PublishAsync(exchange, queue.Name, false, message);
    }
