Fatti

L’utente è al centro dei pensieri di tuttiPochi scrivono applicazioni che pongono l’utente realmente al centro

Solo oggi si parla seriamente di user experienceSolo oggi abbiamo Office 2007 che “prova” a cambiare la logica di applicazioni diffuseSolo oggi con AJAX (e affini) si parla di mash-up e di portare “information at your fingertips”

L’Utente al centro Il modello del futuro: Software + Services

Programmazione dichiarativa e XAML

XAML = Extensible Application Markup XAML = Extensible Application Markup LanguageLanguage

•Usato da WPF per dichiarare ciò che si vuole rappresentare

•Linguaggio di markup per dichiarare oggetti, non solo WPF

•Codice e contenuto sono separati

<Button Width="100"> OK <Button.Background> LightBlue </Button.Background></Button>

XAML

Button b1 = new Button();b1.Content = "OK";b1.Background = new SolidColorBrush(Colors.LightBlue);b1.Width = 100;

C#

Dim b1 As New Buttonb1.Content = "OK"b1.Background = New _ SolidColorBrush(Colors.LightBlue)b1.Width = 100
