The Windows App Studio UWP Samples App allows you to see and adjust the components of the Windows App Studio UWP Controls and Data Sources libraries. With this app, you can browse through the different controls, edit the attributes to see changes in real time, and even copy the XAML, C#, and JSON code. The purpose of the app is to highlight what’s in the Windows App Studio Libraries.
