Loading a UWP DLL

There's some functionality I needed to invoke in a HoloLens application.

I've added the DLL to my assets folder and added a reference to the DLL using the Mono editor. When I try to Build the project in Unity I get the following error.

"Unhandled Exception: System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded"

Any ideas in how to address this?

Thanks, that was it!
