I have been back from vacation for some time but I haven't had time to post anything (i.e. I was on vacation the day Entity Framework went RTM in .NET 3.5 SP1!).
Finally, something happened that I cannot wait to talk about.
Jarek and I went discussing how persistence ignorant classes could be supported by building a layer on top of the EF v1 API for a long time.
He finally figured out a good way to do it. The result is this sample that wraps Entity Framework APIs and uses simple code-generation to create "adapters" and "proxies" for your POCO classes:
You can read Jarek's blog post explaining it all.
We hope people will find it interesting and will send useful feedback that can help us improve the core product.
