This is showing my lack of experience here: I am trying to do exactly that,
but don't know which tools or where the DTO's should live.
given this Ayende snipit:
public class OrderToOrderDTO
{
public delegate void Transformer(Order o, OrderDTO d);
List<Transformer> transforms = new List<Transformer>()
{
(y, z) => z.ID = y.Id,
(x,z) => z.CustomerName = x.Name
};
public OrderDTO Transform(Order k)
{
OrderDTO t = new OrderDTO();
transforms.ForEach((item) => item(k, t));
return t;
}
}
where should it "live"? (Like i said, i'm still trying to figure some things
out)
