Entity Framework - Environment Setup

What’s New in Entity Framework 6?

Framework has a complex API that lets you have granular control over everything from its modeling to its runtime behavior. Part of Entity Framework 5 lives inside of .NET. And another part of it lives inside of an additional assembly that's distributed using NuGet.

  • The core functionality of Entity Framework is built into the .NET Framework.

  • The Code First support, that's what lets Entity Framework use classes in lieu of a visual model, and a lighter way API for interacting with EF are in the NuGet package.

  • The core is what provides the querying, change tracking and all of the transformation from your queries to SQL queries as well as from data return into the objects.

  • You can use the EF 5 NuGet package with both .NET 4 and with .NET 4.5.

  • One big point of confusion - .NET 4.5 added support for enums and spatial data to the core Entity Framework APIs, which means if you're using EF 5 with .NET 4, you won't get these new features. You'll only get them when combining EF5 with .NET 4.5.

Framework 6

Let us now take a look at Entity Framework 6. The core APIs which were inside of .NET in Entity Framework 6 are now a part of NuGet package.

Entity Framework 6

It means −

  • All of the Entity Framework lives insides this assembly that's distributed by NuGet

  • You won't be dependent on .NET to provide specific features like the Entity Framework enum support and special data support.

  • You'll see that one of the features of EF6 is that it supports enums and spatial data for .NET 4
