Castle Windsor

Add reference to MassTransit CastleWindsor NuGet package. The following example shows how to configure a simple Castle Windsor container, and include the bus in the container. The two bus interfaces, IBus and IBusControl, are included.

A sample project for the container registration code is available on GitHub.

TIP

Consumers should not typically depend upon IBus or IBusControl. A consumer should use the ConsumeContext instead, which has all of the same methods as IBus, but is scoped to the receive endpoint. This ensures that messages can be tracked between consumers, and are sent from the proper address.

public static void Main(string[] args)
{
    var container = new WindsorContainer();
    container.AddMassTransit(x =>
    {
        // add a specific consumer
        x.AddConsumer<UpdateCustomerAddressConsumer>();

        // add all consumers in the specified assembly
        x.AddConsumers(Assembly.GetExecutingAssembly());

        // add consumers by type
        x.AddConsumers(typeof(ConsumerOne), typeof(ConsumerTwo));

        // add the bus to the container
        x.AddBus(context => Bus.Factory.CreateUsingRabbitMq(cfg =>
        {
            var host = cfg.Host("localhost/");

            cfg.ReceiveEndpoint("customer_update", ec =>
            {
                // Configure a single consumer
                ec.ConfigureConsumer<UpdateCustomerConsumer>(context);

                // configure all consumers
                ec.ConfigureConsumers(context);

                // configure consumer by type
                ec.ConfigureConsumer(typeof(ConsumerOne), context);
            });

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

    IBusControl busControl = container.Kernel.Resolve<IBusControl>();
    busControl.Start();
}

Using a Windsor Installer

It is sometimes useful to put the initialization into an installer, so that it can use existing components from the container for configuration.

public class MassTransitInstaller :
    IWindsorInstaller
{
    public void Install(IWindsorContainer container,
        Castle.MicroKernel.SubSystems.Configuration.IConfigurationStore store)
    {
        var busConfig = container.Resolve<BusConfiguration>();

        var busControl = Bus.Factory.CreateUsingRabbitMq(config =>
        {
            config.Host(busConfig.HostAddress, host =>
            {
                host.Username(busConfig.Username);
                host.Password(busConfig.Password);
            });

            config.ReceiveEndpoint(busConfig.QueueName, endpoint =>
            {
                endpoint.EnableMessageScope();
                
                endpoint.LoadFrom(container);
                
                // Above method works but it is deprecated, instead below method should be used to get Consumer from container.
                endPoint.Consumer<YourConsumer>(container.Kernel);
            })
        });

        container.Release(busConfig);

        container.Register(Component.For<IBus, IBusControl>().Instance(busControl));

        busControl.Start();
    }
}
