/*
 * This is is similar to what we have done for FileSystem but they did in a weird and really unclear way this time
 * (an abstract class that inherits from an interface? What is the sense? They have not used a class for
 *  any platform but did "kludges" with partial classes).
 * In the end the more simple thing to do is plug things here some it seems only Properties will hit this code
 * while methods will call FileSystem directly... what a mess!
