I have been able to create a viewModel class which maps the fields of my schema using DD4T's "ViewModels" attributes: 

    [ContentModel("Content", true)]
    public class ArticleViewModel
    {
        [TextField(FieldName = "title")]
        public string Title { get; set; }
        [DD4T.Mvc.ViewModels.Attributes.RichTextField]
        public MvcHtmlString Body { get; set; }
    }

I would now like to make use of this in my view. I have an action method in my controller: 

    public ActionResult Component(ComponentPresentation componentPresentation)
    {
        return base.ComponentPresentation();
    }

This gives me a Model of type DD4T.ContentModel.ComponentPresentation, while obviously I would like it to be an ArticleViewModel. I need to do something in my controller to instantiate my ArticleViewModel and have it populated with the fields from the component presentation, but it's not clear to me what the correct way to do this is. Obviously, I could just "new one up" and populate the fields manually, but then what would be the point of the annotations?

Actually - I'm not at all sure that I'm doing the right thing here, so any clarity anyone can add would be useful.
