ADO.Net Entity Data Model Designer (VS2010) is making me INSANE -- hopefully someone has dealt with this and knows how to make it stop.
When initially putting together a complex data model, it's perfectly fine that Designer figures out on its own where the lines delineating associations are placed. However, eventually, I wind up meticulously placing those lines myself for the sake of readability.
But if I finish my layout, and then decide to, say, add a property to an existing entity, Designer redoes my entire layout, or at least every association line that leads to or from that entity.
Is there some way to disable or otherwise get around this automatic layout feature?
