Rhino mocks exception with CompositionContainer

Question

[TestFixture]
public class UnitListViewModelTests
{
    private CompositionContainer _container;
    private INHDataService _nhDataService;
    private INHUnitOfWork _nhUoW;

    [SetUp]
    [TestCase]
    public void create_container()
    {
        _container = MockRepository.GeneratePartialMock<CompositionContainer>();
        _nhDataService = MockRepository.GenerateMock<INHDataService>();
        _nhUoW = MockRepository.GenerateMock<INHUnitOfWork>();

        _container.Expect(x => x.GetExportedValue<INHDataService>()).IgnoreArguments().Return(_nhDataService);
    }
}

this code throws an exception at _container.Expect... .

SetUp : System.InvalidOperationException : Previous method 'IEnumerator.MoveNext();' requires a return value or an exception to throw.

Edit: I tried this also but it still throws an exception:

_container.Stub(x => x.GetExportedValue<INHDataService>()).IgnoreArguments().Return(_nhDataService);

我猜CompositionContainer.GetExportedValue()方法不是虚拟的。
