XAML

XAML（Extensible Application Markup Language )是Windows Presentation Foundation（WPF）和Universal Windows Platform(UWP)的一部分，是微软开发的一種基于XML、基于声明，用于初始化结构化值和对象的使用者介面宣告式程式設計，它有著HTML的外觀，又揉合了XML語法的本質，例如：可以使用****標籤設定按鈕（Button）。它類似Linux平台下的glade。至於WinFX XAML Browser Application（XBAP）是用XAML作界面描述，在瀏覽器中執行的程式，可取代過去的ActiveX、Java Applet、Flash。

XAML本質上屬於一種.NET编程语言，屬於通用語言運行庫（Common Language Runtime），同C#、VB.NET等同。與HTML類似，特点是用來描述使用者介面。XAML的语法格式为：，Application是必備的基本元素。XAML可以定義2D和3D物件、旋轉（rotations）、動畫（animations），以及各式各樣的效果。

{
await new Windows.UI.Popups.MessageDialog("Hello World!").ShowAsync();
