Visual Studio - Create Class library targeting .Net Core

How do I create a class library targeting .Net Core in visual studio 2015?
I found this getting started “guide”, which shows how to create a new .Net Core project using the dotnet command line tool.
Do I need to create somehow a VS project manual based on the generated files (project.json…)?
Is there a way to create a .Net Core DLL inside of VS without using the “dotnet” tool?
