TwoWay binding breaking change in Windows 10 build 10041

Hello there,

In build 10041 two-way binding introduces an annoying breaking change, at least for the Slider control. I haven't tried other controls.

If you bind the slider Value to a property in TwoWay mode and the application programmatically changes the property, then the slider will move (as expected), but it will also call the property setter back again (breaking change).

In Windows 8.x the property setter is not called back, which makes sense because it's the app that changed the property.

Question: is this a bug or an acknowledged breaking change in Windows 10?

Regards,

Ianier
