look into the collection batch-size mapping attribute, you can use
this load subsets of children over multiple queries. convert the
domain object to a dto and send over the wire. if you are using
automapper it could be as simple as
var entities = session
.CreateQuery("from Entity where id in (:ids)")
.SetParameter("ids", ids)
.List<Entity>();
return Mapper.Map<IList<Entity>, Dto[]>(entity);
