LINQ to Entities allows you to update your database.

I've been trying to find a way to use LINQ to update an existing record, but I'm having no success. This is the technique I developed; intellisense dislikes thedb.SubmitChanges() .

public void updateRestaurant(int RestID, int HoursID, string Web, string Desc)
{
    RestaurantsEntities db = new RestaurantsEntities();
    RESTAURANT restDetails = (from RESTAURANT in db.RESTAURANTs
                                    where RESTAURANT.REST_ID == RestID
                                    select RESTAURANT).Single();
    restDetails.HOURS_ID = HoursID;
    restDetails.REST_WEBSITE = Web;
    restDetails.REST_DESC = Desc;

    db.SubmitChanges();
}
