dnx ef 7与asp.net的迁移错误

Question

I am running ASP.NET 5 default project template with EF 7 beta 5 in Windows 10 preview. Inside Visual Studio, the project build is fine without any errors.

When running EF migration using dnx, it gives this error.

Edit: It seems just running dnx . ef dnx . ef alone gives the same error.

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

Try running 'dnu restore'.

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

   at dnx.host.RuntimeBootstrapper.ExecuteAsync(String[] args)
   at dnx.host.RuntimeBootstrapper.Execute(String[] args)

dun restore command works fine without any error.

    J:\vsproj\AspNet.EF7>dnvm list

Thanks for the help.

Change directory from solution folder to project folder with Migrations then run ef command.

I think for you will be J:\\vsproj\\AspNet.EF7\\src\\AspNet.EF7.
