IOC for objects loaded from orm

I like the idea of coding a Rich domain model, and then applying services to the model. Recently I was trying to get just a little closer to a rich domain, by resolving domain object dependencies during their creation via the ORM. I did find nhibernate supports this style, but alas I am currently constrained to use EF4.1 - code first.

The EF4.1 doco is.... Well there isn't any as best I can tell. For EF4 code first I've relied on blog entries, and perusing the API in object browser. In my quest for rich domain, I found no extension point in EF where I could manage entity proxy creation (pre or post load). I tried finding an override in the db context, no luck. I had some hopes there would be extensibility in te object tracker.. Nup :(.

So in the end I opted to wrap the EF model inside an IOC context aware class (spring.net), that way I coud at least get a post orm load IOC approach.
I've used a simple convention; when the ORM loads an entity, the entity full class name is used as a key in the IOC container. If it's found, the IOC is called, to resolve dependancies on the orm created object.

This approach is all I currently have, with ef4.1.
It works fine, for very simple situations, but since I've intercepted out side of the orm, I only get a shot at resolving dependencies on a top-level entity, not on any child objects that the ORMloads, which kind of makes the whole approach invalid, since I want my ORM to load a more complex entity model than just a set of top-level entities .
