Dans Windows 8 semblent se profiler pas mal de changements en vue d'un nettoyage, unification et amélioration des APIs. Extrait:

Far from being a developer disaster, Windows 8 should be a huge leap forward: a release that threatens to make development a pleasure for native, managed, and Web developers alike. The unification of the .NET and native worlds; the full hardware acceleration; the clean, modern APIs; Avalon as the primary solution for creating Windows UIs—this is what Longhorn's WinFX promised all those years ago, and this time around it looks like it might actually happen.
