Unity Dependency Injection Usage

var endpointConfiguration = new EndpointConfiguration("Samples.Unity");

var container = new UnityContainer();
container.RegisterInstance(new MyService());

endpointConfiguration.UseContainer<IUnityContainer>(new ServiceProviderFactory(container));

public class MyHandler :
    IHandleMessages<MyMessage>
{
    MyService myService;

    public MyHandler(MyService myService)
    {
        this.myService = myService;
    }

    public Task Handle(MyMessage message, IMessageHandlerContext context)
    {
        myService.WriteHello();
        return Task.CompletedTask;
    }
}
