Over the next month or so, I'll be looking into the Entity Framework again.   I see this as the progression of L2S, and as a Microsoft-backed technology I simply cannot ignore it.  Personally, I would much rather put my faith in this than an Open-Source project such as NHibernate.

However, as we know, it has it's faults.  Never one to shirk from a challenge however, I also have a feeling deep in my bones that there is always a way.  Just check out Jaroslaw Kowalksi's EF POCO Adapter.


And, as I predicted, the hassle from the community meant they simply had to build this in to the next release.  Almost hot off the press, we have POCO in the EF.

Anyway, I'll be keeping a close eye on this.  While I'm an avid ALT.NETter I also realise the pain and hassle that you can cause yourself by going down that route!

I've been looking at the EF lately and while I've still not settled on how it can be tested (given the lack of persistence agnosticism), I do feel that MS has received enough stick from the community that this will be a feature of v2.

The following article by John Papa provides some good ideas as to how one would use EF as part of an n-tier architecture - http://msdn.microsoft.com/en-us/magazine/cc700340.aspx
