EF classes which inherit from EntityObject descendant RRS feed

  • Question

  • Hi,

    I'm trying to port a test app to the entity framework. All the existing entity classes inherit from a base entity type in our framework, and not being able to do this with the EF entities is a major headache. I understand all the discussions on POCOs and persistence ignorance, but I'm wondering if there may be a compromise I could take advantage of. If I were to make our framework's base entity class inherit from EntityObject, I would then get classes that work with the EF but also

    contain the stuff from our framework that I need to port the app. What's the best way of achieving this? Clearly I could just go in and hand edit the generated classes, but that's a non-starter. I've been looking at the stuff on codegen events in http://blogs.msdn.com/dsimmons/archive/2007/09/01/ef-codegen-events-for-fun-and-profit-aka-how-to-add-custom-attributes-to-my-generated-classes.aspx, and I think I might be able to achieve what I want that way, but before I invest too much effort in that approach, is there an easier way to do this, whilst still using the EDM designer to work on the model?
