How would I use an external library like Accord in my HoloLens Application?

Recently I've been trying to use certain external libraries in my HoloLens application.
Unfortunately, when I try to use the same, I get a number of errors describing either the .net version incompatibility or some Unity editor dependency error.

Is there a clean way to start using external libraries in the HoloLens dev environment?
