When using FluentDialog as a Style for the ContentDialog it'll show up properly in the XAML Designer but the dialog will not appear during actual runtime.
The Styles will be replaced with custom build ContentDialogs. No clue on what the cause of this problem was. If anyone finds out, be sure to comment on this Issue.
