			// The fact we have injected dependencies is really an internal architectural implementation detail to allow for the
			// cross platform and testing concerns of this library. It shouldn't be something calling code worries about and is 
			// not a deliberate extension point, except where adding new platform support in which case...
			// There is a constructor that takes a manually injected dependency anyway, so proper DI using
			// a container or whatever can be done anyway.
