Consider the following example:

public interface ITask
{
    void Execute();
}

public class LoggingTaskRunner : ITask
{
    private readonly ITask _taskToDecorate;
    private readonly MessageBuffer _messageBuffer;

    public LoggingTaskRunner(ITask taskToDecorate, MessageBuffer messageBuffer)
    {
        _taskToDecorate = taskToDecorate;
        _messageBuffer = messageBuffer;
    }

    public void Execute()
    {
        _taskToDecorate.Execute();
        Log(_messageBuffer);
    }

    private void Log(MessageBuffer messageBuffer)
    {}
}

public class TaskRunner : ITask
{
    public TaskRunner(MessageBuffer messageBuffer)
    {

    }

    public void Execute()
    {
    }
}

public class MessageBuffer
{

}


public class Configuration
{
    public void Configure()
    {
        IWindsorContainer container = null;

        container.Register(
            Component.For<MessageBuffer>()
                .LifeStyle.Transient);

        container.Register(
            Component.For<ITask>()
                .ImplementedBy<LoggingTaskRunner>()
                .ServiceOverrides(ServiceOverride.ForKey("taskToDecorate").Eq("task.to.decorate")));

        container.Register(
            Component.For<ITask>()
            .ImplementedBy<TaskRunner>()
            .Named("task.to.decorate"));

    }

}

How can I make Windsor instantiate the "shared" transient component so that both "Decorator" and "Decorated" gets the same instance?

Edit: since the design is being critiqued I am posting something closer to what is being done in the app. Maybe someone can suggest a better solution (if sharing the transient resource between a logger and the true task is considered a bad design)
