title: How do you add a file as a link in a .NET Core library?
body: <p>I've added a .NET Core RC2 class lib to my solution (for fun) and the first thing I usually do is add a link to a shared <code>GlobalAssemblyInfo.cs</code> and edit the existing <code>AssemblyInfo.cs</code> down to the assembly specifics.</p>
  
  <p>So I've just done "Add"->"existing item", located my file and clicked the dropdown of the add button. No "Add as Link" option.</p>
  
  <p>What's the deal? How do I do this with .NET Core?</p>
