The CTP5 release of EF Code First has an updated assembly
name, and new .NET namespace:
Assembly Name: EntityFramework.dll
These names match what we plan to use for the final release
of the library.

The rest of this blog post contains some more details about

Better Support for Existing Databases
EF Code First makes it really easy to create model layers
that work against existing databases. CTP5 includes some refinements that
further streamline the developer workflow for this scenario.
