Use regular portable libraries in .Net Core RC2
<p>I have a C# project that relegates code to Portable Libraries projects, so they can be reused in .Net and Silverlight environments seamlessly.</p>

<p>The PCLs target <code>.Net45</code> and <code>Silverlight 5</code>.</p>

<p>Now I want to use the same PCLs in .Net Core environment. If possible, I want to keep my solution with .Net and Silverlight environments and reuse the Portable projects in a new .Net Core solution.</p>

<p>When I try to add a reference to a regular PCL project from a .Net Core Library, it fails to read the dependency.</p>

<blockquote>
  <p>NU1001 The dependency could not be resolved.</p>
</blockquote>

<p>If I attempt to add a reference to the PCL assembly I get an error:</p>

<blockquote>
  <p>.NET Core projects only support referencing .NET framework assemblies in this release. To reference other assemblies, they need to be included in a NuGet package and reference that package.</p>
</blockquote>

<p>Is it possible to use regular PCLs on .Net Core environment? Or I need to create new .Net Core libraries?</p>

<p>If I need to create new projects, how can I avoid duplicated code?</p>
