EF 6.0.1 | Visual Studio 2013 (.NET 4.5) | fix some performance issues during warm-up for EF models. |
EF 6.0.2 | Visual Studio 2013 (.NET 4.5) | The tooling for Visual Studio 2012 and Visual Studio 2013 is available on the Microsoft Download Center. You only need to install the tooling if you want to use Model First or Database First |
EF 6.1 | Visual Studio 2013 (.NET 4.5) | Tooling consolidation provides a consistent way to create a new EF model. This feature extends the ADO.NET Entity Data Model wizard to support creating Code First models, including reverse engineering from an existing database. These features were previously available in Beta quality in the EF Power Tools. Handling of transaction commit failures provides the CommitFailureHandler which makes use of the newly introduced ability to intercept transaction operations. The CommitFailureHandler allows automatic recovery from connection failures whilst committing a transaction IndexAttributeallows indexes to be specified by placing an [Index] attribute on a property (or properties) in your Code First model. Code First will then create a corresponding index in the database The public mapping API provides access to the information EF has on how properties and types are mapped to columns and tables in the database. In past releases this API was internal |
