UWP app: An unhandled exception is thrown on every launch

Question

Every time I changed the xaml markup in my UWP app, I was getting an unhandled exception and I couldn't run my app in Visual Studio 2022. Now I get this unhandled exception every time I run the app, I need to remove the app build and do rebuild in VS to launch the application. What could be wrong or where could be the error?

Hello there,

To prevent the app from crashing due to unhandled exceptions, it's a good practice to implement global exception handling. In your App.xaml.cs file, you can subscribe to the UnhandledException event to catch and handle exceptions before they crash the app.

public App()
{
    this.InitializeComponent();
    this.Suspending += OnSuspending;
    this.UnhandledException += App_UnhandledException;
}

private void App_UnhandledException(object sender, Windows.UI.Xaml.UnhandledExceptionEventArgs e)
{
    // Handle the exception here, e.Exception provides the exception details
    e.Handled = true; // Set to true to indicate that the exception has been handled
}


Hope this resolves your Query !!
