三、代码结果

四、总结

通过引用微软库中的Buttton样式代码，可以自定义改变控件的样式，主要是通过改变如下部分。

<ContentPresenter x:Name="contentPresenter"
                  Focusable="False" 
                  HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                  Margin="{TemplateBinding Padding}" 
                  RecognizesAccessKey="True" 
                  SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                  VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>

五、热重载工具

在调试窗口界面上方就可以实现很方便的调试功能。
