App is crashing when I use TextBlock styles BodyTextBlockStyle and BodyStrongTextBlockStyle in uwp a-CodePudding

Hi 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://docs.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.

CodePudding user response：
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 .
