Rebus is a lean service bus implementation for .NET, similar in nature to NServiceBus and MassTransit, only leaner.

These are the goals - Rebus should have:

• a simple and intuitive configuration story
• a few well-selected options
• no doodleware
• dependency only on .NET 4 BCL
• integration with external dependencies via small and dedicated projects
• the best error messages
• a frictionless getting-up-and-running-experience

and in doing this, Rebus should align very well with the NServiceBus way of doing things, which I like, thus allowing users (myself included) to easily migrate to NServiceBus at some point in a project's lifetime if Rebus for some reason falls short (which I don't think it will).

Oh, and Rebus is free as in beer and speech.

Because I wanted to build the .NET service bus that I would have the patience to work with every day, probably for several years to come. And I can be very impatient with my tools, so the most solemn goal of Rebus is that it should stay out of my way - and I think it does that just right!

Rebus is a simple .NET library, and everything revolves around the RebusBus class. One way to get Rebus up and running, is to manually go

var bus = new RebusBus(...);
bus.Start();

// use the bus for the duration of the application lifetime

// remember to dispose the bus when your application exits
bus.Dispose();

where ... is a bunch of dependencies that vary depending on how you want to send/receive messages etc. Another way is to use the configuration API, in which case you would go

var someContainerAdapter = new BuiltinContainerAdapter();

for the built-in container adapter, or

var someContainerAdapter = new AdapterForMyFavoriteIocContainer(myFavoriteIocContainer);

to integrate with your favorite IoC container, and then

Configure.With(someContainerAdapter)
	.Logging(l => l.Log4Net())
	.Transport(t => t.UseMsmqAndGetInputQueueNameFromAppConfig())
	.MessageOwnership(d => d.FromRebusConfigurationSection())
	.CreateBus()
	.Start();

// have IBus injected in application services for the duration of the application lifetime

// let the container dispose the bus when your application exits
myFavoriteIocContainer.Dispose();

which will stuff the resulting IBus in the container as a singleton and use the container to look up message handlers. Check out the Configuration section on the official Rebus documentation wiki for more information on how to do this.
