# Connect Endpoint

Receive endpoints should be configured with the bus, so that they are all started at the same time. In some situations, however, a receive endpoint may be needed after the bus has been started. For instance, a request client may want to use a separate queue from responses instead of using the bus's queue. Or it may be that a new consumer is now available, and needs to be connected to the bus.

To connect a new receive endpoint to the bus, use the ConnectReceiveEndpoint method.

var handle = bus.ConnectReceiveEndpoint("secondary-queue", x =>

// wait for the receive endpoint to be ready, throws an exception if a fault occurs
var ready = await handle.Ready;

When connecting a receive endpoint, consumers will configure the broker topology so that messages types are subscribed to topics/exchanges. If the receive endpoint is temporary, the configuration should be skipped, and the ConnectConsumer style methods should be used after the receive endpoint is ready.

# Disconnect an Endpoint

Connected endpoints will be stopped when the bus is stopped. If the endpoint needs to be stopped before the bus, the handle can be used.

await handle.StopAsync();

# Container Integration

When using AddMassTransit with your dependency injection container of choice, receive endpoints can be connected using the IReceiveEndpointConnector interface. When using this interface, consumers which were added during configuration can be configured on the receive endpoint.

To connect a receive endpoint and configure a consumer:

namespace MicrosoftConnect;

using System;
using System.Threading;
using System.Threading.Tasks;
using ContainerConsumers;
using MassTransit;
using Microsoft.Extensions.DependencyInjection;

public class Program
    public static async Task Main()
        var services = new ServiceCollection();

        services.AddMassTransit(x =>


            x.UsingRabbitMq((context, cfg) =>
                cfg.ConfigureEndpoints(context, x => x.Exclude<SubmitOrderConsumer>()));

        var provider = services.BuildServiceProvider();

        var busControl = provider.GetRequiredService<IBusControl>();

        await busControl.StartAsync(new CancellationTokenSource(TimeSpan.FromSeconds(10)).Token);
            var connector = provider.GetRequiredService<IReceiveEndpointConnector>();

            var handle = connector.ConnectReceiveEndpoint("order-queue", (context,cfg) =>

            await handle.Ready;

            Console.WriteLine("Press enter to exit");

            await Task.Run(() => Console.ReadLine());
            await busControl.StopAsync();
