How to: Use System Fonts Keys
System resources expose a number of system metrics as resources to help developers create visuals that are consistent with system settings. xref:System.Windows.SystemFonts is a class that contains both system font values and system font resources that bind to the values—for example, xref:System.Windows.SystemFonts.CaptionFontFamily%2A and xref:System.Windows.SystemFonts.CaptionFontFamilyKey%2A.
System font metrics can be used as either static or dynamic resources. Use a dynamic resource if you want the font metric to update automatically while the application runs; otherwise use a static resource.
Note
Dynamic resources have the keyword Key appended to the property name.
The following example shows how to access and use system font dynamic resources to style or customize a button. This [!INCLUDETLA2#tla_xaml] example creates a button style that assigns xref:System.Windows.SystemFonts values to a button.
