We are excited to announce that Microsoft ADO.NET Entity Framework 4.1 Release Candidate (EF 4.1 RC) is now available. This is a fully supported, go-live release. In approximately one month we plan to release the final Release to Web (RTW). We are not planning any changes to the API surface or behavior between RC and RTW, the release is purely to allow any new bugs found in the RC build to be evaluated and potentially fixed.
ADO.NET Entity Framework 4.1 RC introduces two new features:

There are a number of resources to help you get started with EF 4.1 RC:
Previous releases of Code First were made available as the ‘EFCodeFirst’ NuGet package. The EF 4.1 RC release contains features that are also applicable to Model First and Database First development, therefore we have chosen to adopt the ‘EntityFramework’ package name for this release, and future releases. If you are currently using the ‘EFCodeFirst’ package you will need to swap to the ‘EntityFramework’ package to get the supported go-live release. If you own a package that depends on ‘EFCodeFirst’ we would encourage you to swap the dependency over to the ‘EntityFramework’ package as soon as possible.
This release can be used in a live operating environment subject to the terms in the License Terms. The ADO.NET Entity Framework Forum can be used for questions relating to this release. To contact Microsoft directly please send questions to firstname.lastname@example.org.
The new features in ADO.NET Entity Framework 4.1 RC were previously included in Entity Framework Feature CTP5. The changes since Feature CTP5 include:

It has been great to have so much community involvement helping us drive the new features in EF 4.1. We thank you for giving us your valuable input and look forward to working together on the next release. ADO.NET Entity Framework Team
