Is it possible with any of the collections (bag, list) to be able to add an element to the end of the collection without loading all the existing elements in the collection?

Thanks,

Great! So my understanding is that an IList mapped as a <list> will initialize the entire collcetion when adding to the end. I guess I should replace it with a bag.

Thanks for pointing this out to me.

Will a bidirectional relationship cause an initialize of a bag collection during an Add?

No it will not. I have just been testing this and a bag is the only one that will not get initialized on an add. Removes and inserts will initialize the bag though. I dont think there would be anyway to avoid that.
