title: System.Runtime.Serialization could not be resolved
body: <p>Just as title says, trying to create ASP.NET Core application, or more correctly, migrating from RC2 to Core 1.0.</p>
  
  <p>Got a second construction in project.json:</p>
  
  <pre><code>"frameworks": {
      "netcoreapp1.0": {
        "imports": [
          "dotnet5.6",
          "portable-net45+win8"
        ],
        "frameworkAssemblies": {
          "System.Runtime.Serialization": "4.0.0.0",
          "System.ServiceModel": "4.0.0.0"
        }
      }
    },
  </code></pre>
  
  <p>There are no problems if I remove imports and revert <code>netcoreapp1.0</code> to <code>net451</code> (just like it was before migration attempt) but in the current state I am receiving two issues:</p>
  
  <pre><code>NU1001  The dependency System.Runtime.Serialization &gt;= 4.0.0 could not be resolved.
  NU1001  The dependency System.ServiceModel &gt;= 4.0.0 could not be resolved.
  </code></pre>
  
  <p>I also cant just remove them and hope that nothing will happen because after removal, I am receiving a bunch of <code>are you missing an assembly reference</code> issues.</p>
  
  <p>What possibly am I missing to fix this issue?</p>
  
  <p><strong><em>EDIT</em></strong></p>
  
  <p>Tried to add to dependecies <code>System.Runtime.Serialization.Primitives</code>. Well, it worked out exactly as if I removed <code>System.Runtime.Serialization</code>.</p>
  
  <p>In project I got  such issues as:</p>
  
  <pre><code>The type or namespace name 'Mime' does not exist in the namespace 'System.Net' (are you missing an assembly reference?)
  The type or namespace name 'ServiceModel' does not exist in the namespace 'System'
  </code></pre>
  
  <p>and others</p>
