Code inspection: Use 'nameof' expression when registering a DependencyProperty

This inspection suggests using the nameof expression when registering a DependencyProperty because the nameof expression makes your code more maintainable and less error-prone.

In the example below, using nameof(PageVisibility) instead of "PageVisibility" makes the code more robust and provides compile-time checking of the property name. If you later rename the property PageVisibility, the nameof expression will automatically update to reflect the new name, ensuring consistency and reducing the risk of runtime errors.
