Impossible d'échafauder avec dotnet ef core sur mac

J'essaie d'utiliser le noyau .net pour procéder au reverse engineering de classes de modèles à partir d'une base de données existante sur mon MAC. La base de données s'exécute sur une machine virtuelle avec Windows et je peux y connecter à partir d'osx.

Dans mon projet.json, j'ai les éléments suivants:

"dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.1",
      "type": "platform"
    },
    "Microsoft.AspNetCore.AngularServices": "1.0.0-*",
    "Microsoft.AspNetCore.Diagnostics": "1.0.0",
    "Microsoft.AspNetCore.Mvc": "1.0.1",
    "Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview2-final",
      "type": "build"
    },
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0",

    "Microsoft.Extensions.Logging.Console": "1.0.0",
    "Microsoft.Extensions.Logging.Debug": "1.0.0",
    "Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0",

    "Microsoft.EntityFrameworkCore.Design": {
      "type": "build",
      "version": "1.0.0-preview2-final"
    },
    "Microsoft.EntityFrameworkCore.SqlServer.Design": "1.0.0-rc2-final",
    "Microsoft.EntityFrameworkCore.SqlServer": "1.0.0-rc2-final"
  },

  "tools": {
    "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final",
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final",
    "Microsoft.DotNet.Watcher.Tools": "1.0.0-preview2-final",
    "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true,
    "compile": {
      "exclude": ["node_modules"]
    }
  }

Mais quand je cours

dotnet ef dbcontext scaffold "myDbConnectString" Microsoft.EntityFrameworkCore.SqlServer

J'obtiens l'erreur suivante et je ne peux pas me passer de ça

J'ai essayé de changer les versions de mes dépendances dans les deux sens mais sans résultat. Quelqu'un at-il des indications?
