Anyone have more information for the NS library included in src/Lib? It looks very similar to Batteries or Core so I'm interested in why Microsoft chose to develop their own solution instead. Also, Microsoft hasn't released it as a separate library from SLAyer. Is the whole library being open sourced here (or are they only sharing a small part of it?)? And if so, why doesn't Microsoft create a new repository for it and publish it to OPAM?
