How to reference Windows.Foundation in Unity3d

Question

I want to reference Windows.Foundation in my Unity project. I have played with with the Scripting Runtime Version and API Compatibility level to no avail. I am using IL2CPP as the scripting backend (since .NET is being deprecated).

Can someone please help me figure out how to get Unity to recognize Windows.Foundation ?

I saw this post which seems related but didn't fix it for me. Missing System.Media.Capture.Frames namespace

It is referenced automatically when you build to Universal Windows Platform. See this: https://docs.unity3d.com/Manual/IL2CPP-WindowsRuntimeSupport.html

Note, you cannot reference .winmd files in the editor as it uses Mono to power scripting, and Mono does not support referencing or calling into Windows Runtime APIs.
