Remarks

This method supports WPF XAML processor implementation, and is not intended to be called directly. The XAML processor implementation uses this method for proper handling of DynamicResource Markup Extension values during object creation.

The property to be set by the provided value must be of type DependencyProperty.

This implementation does not rely on any services based on the passed serviceProvider.
