如何回滚到以前的实体框架

Question

Recently I've just updated my Entity Framework in my project from 4.0 to 6.0, after updating I got almost 300 errors, and now it's a mess. I wish to rollback to the previous point where the Entity Framework was 4.0.

How can I do it with .Net Visual Studio 2010?

Answer 1

go to tools -> library package manager -> package manager console

then in the package manager consolo write

Uninstall-Package EntityFramework

finally when it's done

Install-Package EntityFramework -Version 4.1.10311 

you can try 4.3.1 its the newest version for 4.*
