App is crashing when I use TextBlock styles BodyTextBlockStyle and BodyStrongTextBlockStyle in uwp app

Question

I am developing a UWP app and trying to use styles BodyTextBlockStyle and BodyStrongTextBlockStyle. But as soon as I use these styles on TextBlock, app is crashing with following callstack. I see that these styles are standard ones (https://learn.microsoft.com/en-us/windows/apps/design/style/xaml-theme-resources) so I assume I do not need to add any references to the project. But if that is the case, can you please guide me which one to add and how?

Please help.

Answer 1

Crash was because I was using BodyStrongTextBlockStyle and my app is not using WinUI. BodyStrongTextBlockStyle only exists if the app is using WinUI 2.6+.
