Using member 'Avalonia.Markup.Xaml.Styling.ResourceInclude.ResourceInclude(Uri)' which has 'RequiresUnreferencedCodeAttribute' can break functionality when trimming application code. StyleInclude and ResourceInclude use AvaloniaXamlLoader.Load which dynamically loads referenced assembly with Avalonia resources. Note, StyleInclude and ResourceInclude defined in XAML are resolved compile time and are safe with trimming and AOT.
