How to reference Windows specific assemblies like System.Device in a .NET Standard Library?

I have a project with:

<TargetFrameworkVersion>v4.6.1</TargetFrameworkVersion>

and it uses System.Device.dll as reference.

Migrating all .net 4.6.1 class libs to a .NET Standard lib I asked myself how can I add the System.Device.dll to a .NET Standard 2.0 project?

Any Idea?
