The CTP is long time dead with no other version coming because all that stuff is currently part of . NET 4.5 beta and EF 5.0 beta. You must upgrade to those two and the upgrade will consist of re-targeting application back to .
NET 4.0 / . NET 4.5, removing all dependencies to your current EF version and re-adding those dependencies for . NET 4.5 / EF 5.0.
Some time ago I wrote a blog post on this: http://blog.3d-logic.com/2012/04/11/entity-framework-zombie-a-k-a-microsoft-entity-framework-june-2011-ctp/. There is a number of issues with CTP 4.2 because of technical challenges related to shipping a . NET Framework library out of the .
NET Framework (like 4.2 target). Move to . NET Framework 4.5 that contains the same feature set as EF 4.2 + bug fixes and has a go-live license.
Use EF 5.0 on top of it and you will be in a better world.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
