Q:

WPF CheckBox with Rounded Corners

Is it possible to style a WPF checkbox to have rounded corners by modifying a custom style? If so, how is this done?

A:

Best way that I know   
<CheckBox Content="CheckBox" HorizontalAlignment="Left" Height="20" Margin="134,143,0,0" VerticalAlignment="Top" Width="176" Style="{DynamicResource CheckBoxStyle1}"/>
