New Windows 8.1 Controls - Do they work on Windows 8 machines?

Question

Hello everyone,

Windows 8.1 includes a lot of new controls for XAML/C# developers, such as a DatePicker and a Flyout, that Windows 8 lacked. I have made my own versions of these controls for my Windows 8 apps, but I figured I'd utilize the built-in controls and update my apps with them. If I were to replace my custom controls with the Windows 8.1 controls and handle any code changes appropriately, would my apps work fine on Windows 8 machines? I'm wondering whether or not the Windows 8.1 controls are compatible with Windows 8 devices.

Thank you very much in advance for any help!

Answer 1

No. They require apps built for Windows 8.1 and run only on Windows 8.1.

You cannot use the new Windows 8.1 features in a Windows 8 app on either Windows 8 or Windows 8.1
