using EF3.5sp1 for a project, and I've been working around many of its
problems... as such, my entity partial classes have a lot of logic in
them for change-tracking and whatnot. Obviously, I'd like to factor
this logic out into a common base class,
but of course all my objects must derive from EntityObject. Is it
possible to tell them to derive from some class of my own invention
(which would actually likely derive from EntityObject themselves)?
I'd rather avoid editing the EDMX file unless the changes will be
safe on entity-model-update, since I'm still making changes to the
database schema in this early state of my project.
Also, is there any good workaround for the fact that the change isn't tracked when you change EntityReference.EntityKey?
