Question

What techniques are there for debugging issues with data binding in a Windows Metro style application? Are there techniques available like those for WPF and Silverlight applications, described at:

• How can I debug WPF bindings?
• Debugging Data Bindings in a WPF or Silverlight Application
• How can I turn binding errors into runtime exceptions?

EDIT: I was originally asking about WinRT data binding debugging techniques so that I could troubleshoot the issue described at Metro: Why is binding from XAML to a property defined in code-behind not working?. I eventually found a solution to this issue, but experimenting with the working solution, I did not see any message in the Visual Studio 11 output window when I purposely misspelled the property name so that it would not be found. It also does not appear that PresentationTraceSources is available to WinRT apps.

Answer 1

Another possible solution:

sealed partial class App : Application
{
    public App()
    {
        this.InitializeComponent();
        this.Suspending += OnSuspending;
        DebugSettings.BindingFailed += OnDebugSettingsOnBindingFailed;
    }

    private void OnDebugSettingsOnBindingFailed(object sender, BindingFailedEventArgs args)
    {
        new MessageDialog(args.Message).ShowAsync();
    }
    ...
}
