EF Core 1.1 preview1: No executable found matching command "dotnet-ef"

Hi everyone I've the problem with EFCore migration in project on ASP.NET Core.
Some technical info:
OS: macOS

dotnet --version
1.0.0-preview2-003148

Here is my project.json:

{
"dependencies": {
"Microsoft.NETCore.App": {
"version": "1.0.1",
"type": "platform"
},
"Microsoft.AspNetCore.Mvc": "1.0.1",

"Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0",
"Microsoft.Extensions.Configuration.FileExtensions": "1.0.0",

]
}
},
"frameworks": {

"imports": [
"dotnet5.6",
"portable-net45+win8"
],
"buildOptions": {
"emitEntryPoint": true
}
}
},
"buildOptions": {
"emitEntryPoint": true,
"preserveCompilationContext": true
},
"runtimeOptions": {
"configProperties": {
"System.GC.Server": true
}
},
"publishOptions": {

]
},
"scripts": {
"postpublish": [
"dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%"
]
},
"tooling": {
"defaultNamespace": "TTT"
}
}


I launch "dotnet ef" command from project.json folder.

My actions:

1) dotnet restore

2) dotnet ef

After that I get this error: "No executable found matching command "dotnet-ef".

I have static "Main" method in Program class (Program.cs).

Does anyone have an idea what I am doing wrong?

Thanks.

You need to add "Microsoft.EntityFrameworkCore.Tools.DotNet": "1.0.0-preview3-final" to the tools section.
