This is a list of some of all the nice Entity Framework 6 extensions out there that expand the functionality of the Entity Framework 6 runtime. Code generator tools and Frameworks using Entity Framework are not included here, only libraries that extend DbContext or similar.
The EF team has lists of Tools and 3rd party EF providers here: http://msdn.microsoft.com/en-us/data/ee712907
Please let me know if I have missed anything, and I will add it to the list.
Store Functions for EntityFramework CodeFirst
Why: This project uses the basic building blocks to build end to end experience allowing using TVFs in Linq queries and invoking stroed procedures without having to drop down to SQL.
NuGet: Coming soon
Interactive Pre-Generated Views for Entity Framework 6
Why: An alternative is a solution where views are created dynamically only when needed (i.e. views don't exist or are out dated) and then persisted and made available for use by other instances of the same application (be it running in parallel or the same application after a restart). This is exactly the problem Interactive Pre Generated Views project is trying to solve.
Entity Framework Extended Library
Why: Batch Update and Delete, Future Queries, Query Result Cache, Audit Log
Nuget: http://www.nuget.org/packages/EntityFramework61.Extended (forked)
and http://www.nuget.org/packages/EntityFramework6.Extended (forked)
Project: https://github.com/loresoft/EntityFramework.Extended and https://github.com/AdvancedREI/EntityFramework.Extended
Why: EntityFramework.Utilities provides some batch operations for using EF that the EF team hasn't yet added for us. (CUD)
Why: Bulk insert extension for EntityFramework. Insert large amount of data over 20 times faster than regular insert. Supports DB first and code first.
Why: Visual Studio 2012 and 2013 project templates and NuGet packages for client-side entity change-tracking and server-side persistence with Entity Framework extensions.
Why: EntityFramework mapping API gives you ability to know the database info behind the context.
