ShortBus

ShortBus is an in-process mediator with low-friction API

Command

public class DoSomething : ICommand { }

public class DoesSomething : ICommandHandler<DoSomething> {
	public void Handle(DoSomething command) {
	   // does something
	}
}

_mediator.Send(new DoSomething());

Query

public class AskAQuestion : IQuery<Answer> { }

public class Answerer : IQueryHandler<AskAQuestion, Answer> {
    public Answer Handle(AskAQuestion query) {			
		return answer;
	}
}

var answer = _mediator.Request(new AskAQuestion());

IOC Containers

ShortBus currently supports 6 IOC containers

• AutoFac
• Ninject
• Simple Injector
• Structure Map
• Unity
• Windsor

Example configuration of registering handlers using StructureMap:

ObjectFactory.Initialize(i => i.Scan(s =>
{
    s.AssemblyContainingType<IMediator>();
    s.TheCallingAssembly();
    s.WithDefaultConventions();
    s.AddAllTypesOf(typeof (IQueryHandler<,>));
    s.AddAllTypesOf(typeof (ICommandHandler<>));
}));	

Low-friction API

No type parameter noise.

What for?

• Query objects
• Enables subcutaneous testing
• Business concepts as first class citizens
