Nullability of reference types in return type of 'Identity? LocalPeer.Identity.get' doesn't match implicitly implemented member 'Identity IPeer.Identity.get' (possibly because of nullability attributes).

Non-nullable field '_factories' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.
