WPF Styles BasedOn keyless resource

This post isn't so much to share any new found glory on WPF as it is a note to myself. I can never remember the syntax of basing a WPF style upon the existing default style.

For example I may want to create a default style for all of my buttons to have a background of "AliceBlue"

<Style TargetType="Button">
  <Setter value="AliceBlue" property="Background" />
</Style>

If I create another style it will not automatically pick up the default styles set above.

<Style TargetType="Button" x:Key="NewButtonStyle">
  <Setter value="Red" property="Foreground" />
</Style>

The fix is to specify the type as the resource key for the BasedOn property.

<Style TargetType="Button" x:Key="OverrideButtonStyle" BasedOn="{StaticResource {x:Type Button}}">
  <Setter value="Red" property="Foreground" />
</Style>

Notice that the middle button wont get the blue background

<StackPanel>
  <Button>Default</Button>
  <Button Style="{StaticResource NewButtonStyle}">New</Button>
  <Button Style="{StaticResource OverrideButtonStyle}">Override</Button>
</Stackpanel>

Nothing new here!
