Try modifying the application startup code as in the example below
namespace WpfApplication1
{
///
/// Interaction logic for App.xaml
///
public partial class App : Application
{
protected override void OnStartup(StartupEventArgs e)
{
// hook on error before app really starts
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
base.OnStartup(e);
}
void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
// put your tracing or logging code here (I put a message box as an example)
MessageBox.Show(e.ExceptionObject.ToString());
}
}
}
