Part 2 - MVVM/README.zh-cn.md

+            field = value;
            OnPropertyChanged();
            // Also raise the IsNotBusy property changed
            OnPropertyChanged(nameof(IsNotBusy));


@copilot dont' change the ones thatw e have today taht aren't using [ObservableProperty] for in the readme, we are showing the before/after using the toolkit

Fixed in commit 494d9f5. Reverted the manual implementation section (showing bool isBusy; and string title;) in both Chinese README files to preserve the before/after examples that demonstrate INotifyPropertyChanged before introducing the MVVM Toolkit.

CardView now inherits from Border instead of Frame, enabling use of Border-specific styling and features. This may affect the appearance and layout of CardView components in the application.

- Update getter to use `isBusy` instead of `field` - Ensure setter updates `isBusy` and raises PropertyChanged events
