Calling Windows managed .dll from Cordova App. Win

Question

I need to expose a managed .dll to a Cordova App. My thought process here is to create a plugin which itself will communicate with the managed .dll.

This is STRICTLY for Windows10. I don't need to support anything other than Windows10.

Is there a better way to make calls to a managed .dll from a Cordova App than what I outline below? Is a Windows Runtime Component the best way to go about doing this?

As far as I understand, the best route to do this is to create a Windows Runtime Component.

i.e. JavaScript -> calls www\myplugin.js (interface) -> calls windows\myproxyplugin.js -> calls the WinRT component -> calls the managed .dll?

Am I on the right path to doing this? If not can you please offer the best recommended approach for being able to make calls into a managed .dll from a Cordova App
