Loading Unity Content in UWP on HoloLens at Runtime

I'm building a Unity UWP app which will host an unknown number of child applications. The host application would contact a server and load child applications at runtime. Users interact with the host and can discover new content there.

Currently I don't understand how to load self-contained external modules with scripted functionality. By comparison, in a Flex/Flash application you might load an external SWF. In the browser you could point to another .js file. I'm trying to understand how to do this with Unity/UWP.

Here's the closest answer I've found so far:

I don't know how to create assemblies for this purpose nor how to communicate with them once they load. Is there a best practice for what I'm trying to do or documentation on how this can be done, that I may have missed?


I appreciate any leads you might be able to share. Thanks in advance,
Ben
