Ancora a proposito di Longhorn, è uscita l'ultima versione, sempre in beta, di XAMLON. Per chi non sapesse ancora di cosa si tratta (?!?!?) eccovi qui la descrizione presa direttamente dal sito:
XAML is the XML-based presentation layer language for ‘Longhorn,’ the next Windows. Xamlon is XAML Today.
Build .NET Framework application interfaces using Xamlon. Ensure the applications you build today port easily to Longhorn. Create front-ends that work seamlessly on any version of Windows, ‘98 to XP and beyond. Gain invaluable experience today in the Windows development paradigm of tomorrow.
