Asp .Net Core Web API where to subscribe RabbitMQ

Question

I am trying to implement publish/subscribe architecture using Web API and Rabbit MQ message broker. I have two projects in my solution: Publisher and Subscriber.

Publishing is implementing successfully but I cannot find place in my subscriber project to read published message from the queue.

Both of my projects are .Net Core ASP WEB API

Thanks in advance

Thanks for your response. I think I found out best practice of doing that. I registered rabbit as HostedService using AddSingleton method in ConfigureServices Method. IHostedService internally calls ApplicationGetStarted event. So rabbit starts listening there — kakha

You should probably post this as an answer to your own question because it helped me solve my issue (stackoverflow.com/questions/56360983/…). — Sandor Drieënhuizen

Register rabbitMq as HostedService using the AddSingleton method in ConfigureServices Method. IHostedService internally calls ApplicationGetStarted event. So the rabbit starts listening there

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMassTransit(x =>
        {
            x.UsingRabbitMq();
        });

        // OPTIONAL, but can be used to configure the bus options
        services.AddOptions<MassTransitHostOptions>()
            .Configure(options =>
            {
                // if specified, waits until the bus is started before
                // returning from IHostedService.StartAsync
                // default is false
                options.WaitUntilStarted = true;

                // if specified, limits the wait time when starting the bus
                options.StartTimeout = TimeSpan.FromSeconds(10);

                // if specified, limits the wait time when stopping the bus
                options.StopTimeout = TimeSpan.FromSeconds(30);
            });
    }
}
