title: Best class library project for ASP.NET Core v1.1?
body: <p>Well, I know the ASP.NET Core v1.1 is fresh, but I am little playing a with it and  I am a bit confused about the right class library project choosing in the solution. So here is a scenario:</p>
  
  <p>I start in the Visual Studio 2017 with ASP.NET Core web application project template and choose sub-branch  <strong>ASP.NET Core</strong> (= not with .NET Framework).
  Ok, than I would like to add a class library project, but there are two possibilities:</p>
  
  <ul>
  <li>.NET Core Library </li>
  <li>.NET Standard Library</li>
  </ul>
  
  <p>Well, ASP.NET Core v1.0 did not support common class libraries, but it seems v1.1 have no problem with that. So result is, I can reference both types. </p>
  
  <p>So my question - is it ok to reference .NET Standard Library to ASP.NET Core project? Or should I reference .NET Core Library only?  </p>
