ASP.NET MVC running Entity Framework command on the command line

Question

I want to run dnx commands from command line in Visual studio, but it does not work.

If I type the command:

 dnx ef

I get the error:

System.InvalidOperationException: No service for type 'Microsoft.Dnx.Runtime.IApplicationEnvironment' has been registered.
at Microsoft.Framework.DependencyInjection.ServiceProviderExtensions.GetRequiredService(IServiceProvider provider, Type serviceType)
at Microsoft.Framework.DependencyInjection.ServiceProviderExtensions.GetRequiredService[T](IServiceProvider provider)
at Microsoft.Data.Entity.Commands.Program..ctor(IServiceProvider dnxServices)

My project.json contains this:

 "dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-beta8",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final",

 },

"commands": {
    "web": "Microsoft.AspNet.Server.Kestrel",
    "ef": "EntityFramework.Commands"
},

"frameworks": {
    "dnx451": { },
    "dnxcore50": { }
},

I figured it out. If you get errors like this, it probably if because of wrong dependencies. They need to match your environment and other dependencies. I installed the lates of them all and it worked. This is my final dependencies:

 "dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final",
    "Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final",
    "Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-rc1-final",
    "Microsoft.Framework.Configuration.Json": "1.0.0-beta8",
    "EntityFramework.Core": "7.0.0-rc1-final",
    "EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final",
    "EntityFramework.Commands": "7.0.0-rc1-final",
    "Microsoft.Framework.SecretManager": "1.0.0-beta8"
},
