Persistence Ignorance (POCO) Adapter for Entity Framework

Let's face it: Entity Framework suffers from a huge architectural problem: the business entities are tightly couple with Entity Framework.

Here a band-aid: Persistence Ignorance (POCO) Adapter for Entity Framework.

It uses an adapter layer that will translate between POCO objects and Entity Framework-aware objects and provide services on top of POCO objects, such as:

• Change tracking (snapshot-based and proxy-based when possible)

• Transparent lazy loading

• Immutable Value Objects

• Queries (LINQ and Entity SQL)

• Shadow state (maintaining certain persistence-related fields outside of entity class)

It includes a library helper and a code generator which generates the adapter layer.

And here's Kowalsky's article about it.
