title: Installing EF to .NET core library project
body: <p>I am new to .NET core. Trying to get used to it. But its kind of complicated.</p>
  
  <p>I have my poco classes in <em>'solution.Entity'</em> library project and I want to use them to create a database with EF code first in my <em>'solution.Data'</em> library project.</p>
  
  <p>But when I try to install Entity Framework via Nuget to my <em>'solution.Data'</em> project it says <strong>'Package Restore Failed. Rolling back...'</strong></p>
  
  <p>Both projects are <strong>.NET Core Library projects.</strong></p>
  
  <p>What do I need to do to be able to use EF in .NET core library projects? It's look like I need some kind of configuration. </p>
  
  <p>Thanks for helps.</p>
