</WEBHighlights
HighlightsImportant stuff
• Entity Framework 7 is the next version of EF – Microsoft’s Data API• Built on .NET 4.5.1+ and .NET Core• Runs on Windows Phone and Windows Store apps, Linux and
Mac – wherever .NET Core is available• Supports non-relational data stores and in-memory• Scheduled for Q1 2016 – feature complete now
Not recommended for production usage!
</WEBChanges
ChangesWhat’s new
• Totally rewritten code base• Provider-based: built-in providers include in-memory, SQL
Server, SQLite, PostgreSQL, SQL Server Compact Edition, Redis and Azure Table Storage• Available on GitHub: https://
github.com/aspnet/EntityFramework• Different Nuget packages for different providers – very
modular• Some cool new features, but many won’t be available on
v7.0• Improved SQL generation
</WEBDepartures
DeparturesRemoved features
• ObjectContext API• Entity-SQL – should use LINQ or SQL instead• Model-first (aka, EDMX) – use database first or code first• Database initializers – use migrations• .NET 4.x support• Automatic migrations – customize generated migrations
</WEBNewcomers
NewcomersFunctionality previously unavailable
• .NET Core makes it possible to run on Mac, Linux, Windows Phone, Windows Store• Provider model makes it possible to support non-relational
data stores (e.g., in-memory, NoSQL)• Pluggable primary key generators (e.g., HiLo, sequence,
identity, manual)• Batching of Creates, Updates and Deletes• Mixing of LINQ and SQL• Executing client-side functions in LINQ• Shadow properties – properties that do not exist in the
POCO model

</WEBStill expected
Still expectedWill be ready when launched
• Logging• Full data annotations support• Cascade deletes of orphans• Table Per Hierarchy inheritance pattern

</WEBNot now
Now nowIn the backlog for later
• Lazy and eager loading• Custom conventions• Table Per Class, Table Per Concrete Class patterns• Entity/table splitting• Many:many relations without middle entity• Data seeding• Full logging• Generate model from the database• Complex types• Stored procedures support for CUDs• Connection resiliency• Interception• Azure Table Storage, Redis• Type conversions
</WEBMaybe some other time...
Maybe some other time...May be available in the future
• Different kinds of collections (maps, sets)• Collections of value types• Lazy properties• Formula properties• Filters
