EF6迁移已停止在VS 2015 RC上运行

Question

我现在一直在使用VS2015CTP我决定将其升级到VS2015社区RC由于某些未知原因我的项目上的迁移停止了工作.

在Visual Studio 2015中,我收到以下消息>

You cannot call a method on a null-valued expression.

如果我在VS 2013中打开解决方案并运行上面的命令一切正常.这是VS中的一些错误,它是否失去了对某些东西的引用？有没有办法激活某种更广泛的日志,我真的不觉得调试EF.

谢谢

编辑:我认为这与在Visual Studio 2015中处理Nuget的方式有关,似乎它没有以同样的方式查看nuget.config.我在同一个文件夹中包含多个解决方案的所有包,为此我在.nuget文件夹下使用nuget.config:

<config>
    <add key="repositoryPath" value="G:/Projects/packages" />
</config>

出于某种原因,似乎VS2015没有像VS2013那样处理它,因为它试图将软件包下载到解决方案文件夹下的文件夹包中.

将实体框架版本从6.1.3降级到EF 6.1.2,现在可以正常运行.
