在CarouselView - Xamarin里面的ListView中绑定Itemsource

Question

我试图将ListView放在CarouselView中，但元素绑定不起作用。

如果我注释掉ListView，该项目将正常工作 错误是

  

绑定：在'上找不到'Contenido'属性   'App.ViewModels.FeedListViewModel'，目标属性：
  'Xamarin.Forms.ListView.ItemsSource'

代码如下：

视图模型

public class Feed
{
    public int IdFeed { get; set; }
    public String Title { get; set; }
    public bool HasNewElements { set; get; }
    public ObservableCollection<NewsFeedDocument> Contenido { get; set; }
}

public class FeedListViewModel : MenuViewModel
{   
    public ObservableCollection<Feed> Feeds { get; set; }

    public FeedListViewModel()
    {
        Feeds = new ObservableCollection<Feed>();
        for (int i = 0; i <= 12; i++)
        {
            //Creamos lista de elementos Feed
            NewsFeedDocument documento = new NewsFeedDocument();
            documento.Titulo = "TITULO dasd dsa dsa dsa dsa";
            ObservableCollection<NewsFeedDocument> ElementsX = new ObservableCollection<NewsFeedDocument>();
            ElementsX.Add(documento);
            Feeds.Add(new Feed
            {
                IdFeed = i ,Title = "SECTOR" + i,
                Contenido = ElementsX
            });
        }
        Position = 0;
    }

    private int _position = 0;

    public int Position 
    {
        get { return _position; }
        set { _position = value; RaisePropertyChanged(() => Position); }
    }
}   
}
