MVC4 EF5创建控制器时，不会显示我的上下文

Question

My Context shows up properly when Entity Framework 6.1.3 installed but since scaffolding isn't supported in Entity Framework 6 I had to downgrade it to version 5.0.0. Now when I try to create a new controller my context isn't listed in the drop down list in Data Context Class:

Is this some sort of bug ? Image HERE

What's even more surprising is that it works on a copied version of the same solution.

我通过重新构建解决方案来修复它，重新安装了Entity Framework 5.0.0，然后在添加控制器时在数据上下文列表中手动键入我的上下文。
