dnx ef 7 与 asp.net 的迁移错误

Question

我在 Windows 10 预览版中使用 EF 7 beta 5 运行 ASP.NET 5 默认项目模板。在 Visual Studio 中，项目构建没有任何错误。

使用 dnx 运行 EF 迁移时，出现此错误。

编辑：似乎单独运行 dnx . ef 会产生相同的错误。

J:\vsproj\AspNet.EF7>dnx . ef migration add Intial

Try running 'dnu restore'.

   at Microsoft.Framework.ApplicationHost.Program.ExecuteMain(DefaultHost host, String applicationName, String[] args)
   at Microsoft.Framework.ApplicationHost.Program.Main(String[] args)

dun restore 命令运行良好，没有任何错误。

    J:\vsproj\AspNet.EF7>dnvm list

感谢您的帮助。

使用 Migrations 将目录从解决方案文件夹更改为项目文件夹，然后运行 ​​ef 命令。

我想你会是 J:\vsproj\AspNet.EF7\src\AspNet.EF7。
