[severity:It's more difficult to complete my work]
Create a new WPF project using Visual Studio 2019.
Import a custom font (.ttf) and add it as a resource in App.xaml
Create a style for a control (e.g. Label) and apply it to a control in MainWindow.xaml
Add your custom font resource as the font family value for the new style
Notice that while the custom font appears in the designer, but it doesn't work in release and debug mode.
Note: if you just apply the font directly it works, but not if you apply it from a style
