title: Include referenced project in nuget package
body: <p>I have a solution with 3 projects (using netstandard1.4). Project A contains shared code. Project B is a server side library and project C is a client side library. Project B and C include project A as project reference.</p>
  
  <p>Now I want to publish project B and project C as a nuget package.</p>
  
  <p>The Problem is the nuget packages for project B and C do not contain the code / dll from project A. It looks like project B and C want project A also as a nuget package.</p>
  
  <p><strong>How can I pack the project B and C as standalone nuget packages?</strong> I don’t want to publish project A as a nuget package.</p>
