我可以回去EF5？ [英] Can i go back to ef5?

问题描述

MVC4 / EF5 VS2012最终我做了升级到EF6，认为它可能有问题有所帮助。

MVC4/EF5 VS2012 ultimate and I did an upgrade to EF6, thinking it might help with a problem.

我现在发现我不能创建一个支架控制器。 MS明确表示，他们不会支持在脚手架MCV4。我不知道够不够试图脚手架自己。

I now find I cannot create a scaffold controller. MS clearly says they will not support scaffold in MCV4. I don't know enough to attempt to scaffold myself.

我是一个新手，并试图通过修改/应用Conosto我的需求，勉强能够维持去学习。
我不再看的NuGet EF5。我有另一台计算机上VS2012 / mvc4和EF5。

I'm a newbie and trying to learn by modifying/applying Conosto to my needs, barely able to keep going. I no longer see EF5 in NuGet. I do have another computer with VS2012/mvc4 and EF5.

我可以重新安装附带EF4.1 VS2012我可以再复制EF5（因为我不能的NuGet它）。

I can reinstall VS2012 which comes with EF4.1 Can I then copy EF5 (since I can't NuGet it).

难道我只是找到合适的文件夹，复制EF5，改变webconfig（或者）？我应该采取什么步骤。

Could I just find the proper folder, copy ef5, and change webconfig (or where)? What steps should I take.

我只是看着MS API笔记上升级到MVC5，它似乎令人生畏一个新手。
建议？建议？

I just looked at MS API notes on upgrading to MVC5 and it seems daunting to a newbie. Suggestions? Recommendations?
