I have finally managed to find some time to publish the source code of the post series I wrote some months ago (about how to build an n-tier application using Entity Framework and POCOs).
As this is a complete solution integrated with an IoC container (in this case, MEF), some of the already published code has changed. I have updated the previous posts so that both the source code and the snippets are synchronized.
You can download the source code from here:
Hope this helps.
