Style Hierarchies
In the solution to the last exercise, I created two different styles for the Label elements, and pointed out that there was a lot of duplication. The Style.BasedOn property lets you avoid the duplication:
Instead Of
<Style x:Key="BasicLabel" TargetType="Label">
 <Setter Property="Margin" Value="5" />
 <Setter Property="HorizontalAlignment" Value="Right" />
 <Setter Property="VerticalAlignment" Value="Center" />
 <Setter Property="FontWeight" Value="Black" />
</Style>
<Style x:Key="RequiredLabel" TargetType="Label">
 <Setter Property="Margin" Value="5" />
 <Setter Property="HorizontalAlignment" Value="Right" />
 <Setter Property="VerticalAlignment" Value="Center" />
 <Setter Property="FontWeight" Value="Black" />
 <Setter Property="Label.Foreground" Value="Chocolate" />
</Style>
