        Because of = () => Presenter.Dispose();

        It should_dispose_the_unit_of_work = () => A.CallTo(() => UnitOfWork.Dispose()).MustHaveHappened();

        class TestPresenter : Presenter<IView>

    public interface IUnitOfWork : IDisposable
    {
        void Commit();
        void RollBack();
    }

    public abstract class Presenter<TView> : IPresenter<TView> where TView : class
    {
        readonly TView _currentView;
        readonly IUnitOfWork _unitOfWork;

        protected Presenter(TView currentView, IUnitOfWork unitOfWork)
        {
            _currentView = currentView;
            _unitOfWork = unitOfWork;

            Ensure.That(currentView).IsNotNull();
            Ensure.That(unitOfWork).IsNotNull();

        public TView CurrentView

            get { return _currentView; }
        }

        public virtual void Dispose()
        {
            _unitOfWork.Dispose();
        }

        protected void ShowDialog(IView newForm, object parent)
        {

    public interface IPresenter<out TView> : IDisposable

OK, thank you Björn :)
