If you know that you're going to need to serialize ALL of the children of a graph, you could session.Get() all levels of the graph at the start of the call. NH will then link the entities up for you and avoid return trips to the DB. Unless your entities are HUGE (blob size binary data) then genera

[nhusers] Re: NHibernate relations

My point was about designer. As for lazy loading... it's simply not that advanced to use proxies. It also lacks in other areas and L2S vs. Nhib is not a question. It's unfair to dismiss L2S on the premise of "it has visual designer, that is bad" :) On Mon, Sep 22, 2008 at 5:48 PM, Ken Egozi <[EMAI

You also need to hand craft management of back references when you do POCOs, in order to avoid "Attempt to break an association" exception. But in fairness it is for sure more capable than many people think. On Mon, Sep 22, 2008 at 2:48 PM, Ken Egozi <[EMAIL PROTECTED]> wrote: > urban legend? >
