title: How do I import a .NET Core project to another .NET Core project in Visual Studio?
body: <p>I need to use some classes from another project. How can I just import or create a reference to that project in Visual Studio?</p>
  
  <p>Right now if I use "Add reference" in Visual Studio, I get the error:</p>
  
  <pre><code>".NET Core projects only support referencing .NET framework assemblies in this release. &lt;br/&gt;
   To reference other assemblies they need to be included in a NuGet package"
  </code></pre>
