Workaround for WPF Freezable bug?

January 9, 2024 by Tarik

To workaround this .net bug, change all of the Solid Color Brushes in your code to be freezeable. For example

<SolidColorBrush x:Key="WindowBackground" Color="Black" />

should be changed to:

<SolidColorBrush po:Freeze="True" x:Key="WindowBackground" Color="Black" />.
