Binding Bug Reproduction Repository

This contains the app you can use to debug the MVUX binding bug.

Project specs:

• Made in Visual Studio 2026
• MVUX selected
• .NET 10
• Fluent Design (WinUI) picked
• Navigation set to None (in the setup—I didn't choose Regions)

Running and testing:

Note

You might need to adjust some Debug and Output settings in Visual Studio (like Output logging verbosity) to see the error or find useful information.

AppModel.cs

The minimal application MVUX ViewModel, with an example variable.

MainPage.xaml and MainPage.xaml.cs

The page where the bound value from the variable in AppModel should show (in the button).
