title: I cannot reference .Net Standard 2 library in .Net Core 2 project
body: <p>I have created a .Net Standard 2.0 class library and created some simple Dtos. Then I tried to reference it in .Net Core 2.0 web application and I could no do it. Visual Studio noticed that I should make a reference, but when I did that - nothing happened.</p>
  
  <p>I'm using Visual Studio 15.5.1.</p>
