The following code snippet demonstrates how to use event to catch exceptions that are not taken care of in the logic block / code segment.

//adding event for the error handler
//add event to the app.xaml.cs file
public App()
        {
            this.InitializeComponent();
           
            this.UnhandledException += App_UnhandledException;
        }
 
//taking care of the exception in the event
 
void App_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            //handle/log error that occurs .
            //details of the error are in the e.exception object
        }
