title: Trying to port a .NET 4.0 project to .NET Standard 1.4 with ConfigurationSection
body: <p>I've got a .NET 4.0 project which I'm trying to convert to .NET Standard 1.3 or 1.4.</p>
  
  <p>In my 4.0 project it currently has some <code>ConfigurationSection</code> code which I'm not sure how to port.</p>
  
  <p>I understand with .NET <strong>Core</strong> that things have changed with config files and stuff, but this is a .NET <strong>Standard</strong> class library so I'm not sure how this works/what this means.</p>
  
  <p>What is the recommended thing to do?</p>
  
  <p>Is it literally use a specific NuGet package and I'm good? Does this mean I need to change some code so it's more xplat happy, though?</p>
