title: Is it possible to build a .NET Core library for a UWP project targeting Windows 10 Creators Update (15063)?
body: <p>I'm writing a UWP app, but one of the bits I've developed is something I want to release separately, as a library. I'd like to use .NET Core for maximum portability, but VS won't let me add a .NET Core library to my UWP project as a reference.</p>
  
  <p>Are there any versions of .NET Core that are supported on Windows 10 Creators Update, aka version 15063? If not, how can I make my library portable - am I just stuck building two libraries for UWP and .NET Core?</p>
