實體框架發布揭秘 (Entity Framework Releases Demystified)
I am starting up working with the Entity Framework and I am seeing several versions.
In looking at blog posts I am finding reference to:
- Entity Framework Feature CTP 4
- Entity Framework Feature CTP 5 (few references to this, so it may not really exist)
- Entity Framework 4.0
- Entity Framework 4.1
Can someone tell me what order these go in and which ones are contained in others (for example are the features for Entity Framework Feature CTP 4 in Entity Framework 4.1?).

方法 1:
Entity Framework 4.0 was released with .NET 4.0
in late February, Entity Framework 4.1 went RTM. It isn't a new version of EF4 but just an add‑on
CTP4 and CTP5 are just public betas of EF4.1 released before the RTM went live.
As far as I know, EF4.1 is CTP5.
Here you can read the changes from CTP4 to CTP5: http://blogs.msdn.com/b/adonet/archive/2010/12/10/code‑first‑mapping‑changes‑in‑ctp5.aspx
