I am new to entity framework and mvc.
I am trying to understand what a Controller should pass to the view.
Should it be the class from Models (MySolution.Models.Story) or the class from the entity framework (MySolution.Story).
The problem is that if I pick the one from entity framework, then the DataTypes and html-helpers are not working correctly. If I pick the class from models, then I can’t convert from the entity class to the model class, for example: 

TrendEntities TrendDB = new TrendEntities();
public ActionResult Details(int id) {  
  var Country = TrendDB.Countries.FirstOrDefault(c => c.CountryId ==id);  
  return View(Country);  
}

    Just use the adp.net entity framework POCO templates to generate. download the template. right click in the entity designer and select “add code generation item” and choose the poco template. Now your objects dont have all of the ‘entity framework baggage’ with them. Proxies are automatically created behind the scenes and you don’t need to do any object mapping.
    You can find this template by adding a new item to visual studio 2010, and searching the online templates from within the add dialog for POCO. The template name is:

    ADO.NET C# POCO Entity Generator
