Solving error "Microsoft.NETCore.App 1.0.0 does not support framework .NETFramework,Version=v4.6.1"
<p>I have an ASP.NET Core 1.0 complete application running using <code>net461</code> references. Now I am trying to add another framework - <code>netcoreapp1.0</code>. For this, I have updated my project.json like this:</p>

<pre><code>{
   "userSecretsId":"",
   "version":"2.4.0-*",
   "buildOptions":{
      "emitEntryPoint":true,
      "preserveCompilationContext":true
   },

      "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore":"1.0.0",
      "Microsoft.AspNetCore.Identity":"1.0.0",
      "Microsoft.AspNetCore.Identity.EntityFrameworkCore":"1.0.0",
      "Microsoft.AspNetCore.Mvc":"1.0.0",
      "Microsoft.AspNetCore.Mvc.TagHelpers":"1.0.0",

      "Microsoft.AspNetCore.Server.Kestrel":"1.0.0",
      "Microsoft.AspNetCore.StaticFiles":"1.0.0",

   },

      "Microsoft.AspNetCore.Server.IISIntegration.Tools":"1.0.0-preview2-final",

   },
   "commands":{

   },
   "frameworks":{
      "net461":{

      },
      "netcoreapp1.0":{
         "imports":[
            "dotnet5.6",
            "portable-net45+win8"
         ]
      }
   },
   "runtimes":{
      "win10-x64":{

      },
      "win81-x64":{

      },
      "win8-x64":{

      },
      "win7-x64":{

      }
   },
   "publishOptions":{
      "exclude":[
         "**.user",
         "**.vspscc",
         "wwwroot",

      ]
   },
   "scripts":{
      "prepublish":[
         "npm install",
         "bower install",
         "gulp clean",
         "gulp min"
      ]
   }
}
</code></pre>

<p>After modifying project.json, I got this error:</p>

<blockquote>
  <p>Failed to make the following project runnable: MVC6_Full_Version
  (.NETCoreApp,Version=v1.0) reason: Expected coreclr library not found
  in package graph. Please try running dotnet restore again.</p>
</blockquote>

<p>To resolve this, I ran <code>dotnet restore</code> command but no luck.</p>

<p>Then, I added this block:</p>

<pre><code>"Microsoft.NETCore.App": {
  "version": "1.0.0",
  "type": "platform"
},
</code></pre>

<p>After adding this block, I got a different error:</p>

<blockquote>
  <p>Code: NU1002 Description: The dependency Microsoft.NETCore.App 1.0.0
  does not support framework .NETFramework,Version=v4.6.1.</p>
</blockquote>

<p>Basically, I want to add both references in my applications - .NET Framework 4.6.1 and ASP.NET Core 1.0.</p>

<p>How do I resolve this error?</p>
