title: Where Project.json tools should go now?
body: <p>I'm following <a href="https://docs.microsoft.com/en-us/ef/core/get-started/aspnetcore/existing-db" rel="nofollow noreferrer">Entity Framework Core instructions</a> step by step. At some point it says to </p>
  
  <blockquote>
    <p>locate the tools section and add the
    Microsoft.EntityFrameworkCore.Tools.DotNet package as shown below</p>
  </blockquote>
  
  <p><code>project.json</code>:</p>
  
  <pre><code>"tools": {
     "Microsoft.EntityFrameworkCore.Tools.DotNet": "1.0.0-preview3-final",
     "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final",
     "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
   },
  </code></pre>
  
  <p>As I understand, project.json is gone now. So where am I supposed to add this value? Project file?</p>
