Consumer twice

I just follow the example ：

builder.AddMassTransit(x =>
             {
                 //x.AddConsumers(Assembly.GetExecutingAssembly());
                 x.AddConsumer<DoSomethingConsumer>();
                 x.AddBus(context => Bus.Factory.CreateUsingRabbitMq(cfg =>
                 {
                     var host = cfg.Host(new Uri("rabbitmq://localhost/SkyWatch"), h =>
                     {
                         h.Username("SkyWatch");
                         h.Password("sky_watch_2019_best");

                     });

                     cfg.ReceiveEndpoint("web-service-endpoint", ec =>
                     {

                         //ec.ConfigureConsumers(context);
                         ec.Consumer<DoSomethingConsumer>();
                     });

                     // or, configure the endpoints by convention
                     cfg.ConfigureEndpoints(context);

                 }));
                 
                 //x.AddRequestClient<DoSomething>(new Uri("rabbitmq://localhost/SkyWatch/web-service-endpoint"));
             });

call consumer twice but when I remove " x.AddConsumer<DoSomethingConsumer>();" it works fine. how

Yeah, you’re using every example instead of just one approach.

Use either:

builder.AddMassTransit(x =>
{
    x.AddConsumers(Assembly.GetExecutingAssembly());

    x.AddBus(context => Bus.Factory.CreateUsingRabbitMq(cfg =>
    {
        var host = cfg.Host(new Uri("rabbitmq://localhost/Test1"), h =>
        {
            h.Username("SkyWatch");
            h.Password("sky_watch_2019_best");
        });

        cfg.ConfigureEndpoints(context);
    }));
});

or

builder.AddMassTransit(x =>
{
    x.AddConsumers(Assembly.GetExecutingAssembly());

    x.AddBus(context => Bus.Factory.CreateUsingRabbitMq(cfg =>
    {
        var host = cfg.Host(new Uri("rabbitmq://localhost/Test1"), h =>
        {
            h.Username("SkyWatch");
            h.Password("sky_watch_2019_best");
        });
        
        cfg.ReceiveEndpoint("web-service-endpoint", ec =>
        {
            ec.ConfigureConsumers(context);
        });    
    }));
});

You can create a consumer definition, or you can configure the endpoint when registering the consumer.

Or Use

x.AddConsumer<T>()
    .Endpoint(e => ...);
