Sending and receiving raw messages using NServiceBus transport infrastructure

NServiceBus.Raw

Sending and receiving raw messages using NServiceBus transport infrastructure. NServiceBus to messaging is like Nissan Patrol to off-roading -- a full-featured and mature tool that has all the things you might ever need. NServiceBus.Raw, on the other hand, is like an off-road buggy. It has the same Nissan Patrol super-durable axles and engine but offers no ammenities other than a chair and a steering wheel.

Configuration

Configuration of raw endpoints is very straightforwards and follows the same patterns as regular NServiceBus endpoint configuration

var senderConfig = RawEndpointConfiguration.Create("Sender", OnMessage, "error");
senderConfig.UseTransport<MsmqTransport>();

var sender = await RawEndpoint.Start(senderConfig).ConfigureAwait(false);

Sending

The following code sends a message to another endpoint

var headers = new Dictionary<string, string>();
var body = GetMessageBody();
headers["SomeHeader"] = "SomeValue";
var request = new OutgoingMessage(Guid.NewGuid().ToString(), headers, body);

var operation = new TransportOperation(
    request, 
    new UnicastAddressTag("Receiver"));

await sender.SendRaw(
    new TransportOperations(operation), //Can have multiple sends in one batch
    new TransportTransaction(), 
    new ContextBag())
    .ConfigureAwait(false);

Receiving

The following code implements the on-message callback invoked when a message arrives at a raw endpoint

static Task OnMessage(MessageContext context, IDispatchMessages dispatcher)
{
    var message = Deserialize(context.Body, context.Headers["SomeHeader"]);

    Console.WriteLine(message);
    return Task.FromResult(0);
}
