什么版本的EntityFramework的带外组件应该与.NET 4一起使用？

Question

For deployment reasons, my development team is currently stuck with .NET 4.

However I would like to use the out-of-band EntityFramework.dll library (in order to use the DbContext API), but I have not been able to find any information regarding whether EntityFramework.dll v5 only targets .NET 4.5 or if it can work (albeit with reduced performance and features) on .NET 4.0.

In a nutshell: Can I use EntityFramework.dll 5 with .NET 4.0? Or should I use EntityFramework.dll 4.3?

Answer 1

The NuGet EntityFramework 5 package contains both Entity Framework 5.0 and Entity Framework 4.4 DLLs. If you include it in a .NET 4 project, you'll get the 4.4 version. If you include it in a .NET 4.5 project, you'll get the 5.0 version. As you suspected, 4.4 lacks some features that did make it into 5.0. You cannot use the 5.0 version in a .NET 4 project, but the 4.4 version will work just fine.

Answer 2

实体框架5（nuget包）适用于.NET 4.有一些新功能（空间类型，自动查询编译）需要.NET 4.5，但你可以完成90％的EF开发。
