该包的EntityFramework上未安装项目的比赛。

解决方案

只要更新的NuGet到2.x的EF 5.0需要它。

I am having trouble getting the EF to install on my very simple project called 'Match' (just now learning MVC, better late than never). The general context here is that I created the Model class with only 2 fields and now I want to change the Model class to have a few more fields/properties. I have made the change in the Model class and am now trying to update the DB to match. I am trying to use Update-Database from EF to do that.
