Using Addressable System to Build Asset Bundles for UWP

Hello,

Is it possible to build asset bundles for a UWP / WSA Store / Hololens app using the Linux version of Unity?

I was told that the new Addressables system allows for this - but if that system uses AssetBundles underneath, then I would think UWP build support is still required.

Anyone?

any further docs on implementing custom hosting services?
