本文配合免费下载的Kaxaml 工具，演示XAML 的一些基本用法。关于Kaxaml 工具的介绍和下载，请参考文章：推荐一款免费下载 XAML 编辑调试工具-Kaxaml。
XAML 系列文章为学习笔记，这是我今年春节期间安排的学习任务。

Introducing XAML: A Declarative Way to Create Windows UIs

Paragraph
Before the appearance of .NET 3.0, web applications were written with "markup
languages" such as HTML and Windows applications were not. We may have
dragged controls onto forms, but the creation of the controls and their
properties was managed by the development environment, or you instantiated
them programmatically at runtime.

在我们的范例中，DockPanel 用来从左到右布局元素（尽管可以通过设置属性来靠边-left, right, top 和 bottom），然而 StackPanel 用来从上到下堆放元素。
