where can I get Microsoft.Data.Objects

Where can I download the dll/sdk that contains the Microsoft.Data.Objects namespace it appears that go开发者_如何学运维ogle doesn't know. Thanks

There are new pieces to Microsoft.Data.Objects in the CTP4 (code first) release of Entity Framework 4. See http://www.microsoft.com/downloads/en/details.aspx?FamilyID=4E094902-AEFF-4EE2-A12D-5881D4B0DD3E

That may be what you are looking for??

You're looking for the Entity Framework. Also see here for getting started.

MSDN isn't terribly clear on this but:

The System.Data.Objects namespace includes classes that provide access to the core functionality of Object Services. These classes enable you to query, insert, update, and delete data by working with strongly typed CLR objects that are instances of entity types.
