There's a new project that I want to write with EF recently. Read some information from the Internet, learn the basic Crud method, ready to get hands to try.

The development environment is Visual Studio SP1 found many ways to not. Update to 6.1.3 or not. Two days of tossing. The discovery should be a problem with the development environment. NET 4.0.

There's an explanation on StackOverflow.

Entity Framework 4.0 (System.Data.Entity.dll) is part of. NET 4.0. There is no separate download. EF 4.1 AD EF 4.2 is distribution of EntityFramework.dll (not System.Data.Entity.dll). EF 4.2 are only distributed as NuGet and are not the installed to GAC.

Reverse Engineer Code First is not part of any of the these tools. It is part of the EF Power Tools CTP 1 which is most probably dependent on EF 4.1 (it was released prior to EF 4.2 and there I s possibility that it doesn ' t work with EF 4.2). This tool itself have no relation to functionality of the Entity framework.

Using EF also adds System.Data.Entity.dll This, which is from. NET 4.0. The information on the Internet should be 4.5 of the environment. The environment on the company intranet server is still 4.0 without updates. EF Many advanced new features are still very moving, this time with a LINQ bar.
