Since v3 there has been a move to support orms other than efcore, #291 tracks Marten support, Mongo already exists as a separate package. Nhibernate is a well-known orm with a large userbase which would benefit from being supported by JADNC. This issue aims to track progress to do this. If anyone has already started working on an adapter please feel free to share as I would like to avoid reinventing the wheel.
