It is possible yes. I myself include a reference to the last alpha version bilblioteca in a project . NET core 2.0 and did not give any Warning. Usually when there is incompatibility problem the compiler issues a Warning.

If this does not work for you, Voce should include the source indicated by them in your package sources list.

It is compatible because it implements the . NET Standard. Basically the . NET Standard allows you to write a library compatible with any version of the framework that supports the same standard. What this means is that packages that use the . NET Framework (for example 4.6.x, 4.7.x, ...) can be used in . NET core.
In the same way that libraries written on the . NET core platform will be compatible with the . NET framework. Of course, provided they implement the same version of the Standard.
