You can subscribe to global event handler like AppDomain.UnhandledException
and check the method that throws exception:
AppDomain.CurrentDomain.UnhandledException += CurrentDomainOnUnhandledException;
private static void CurrentDomainOnUnhandledException(object sender, UnhandledExceptionEventArgs unhandledExceptionEventArgs)
{
var exceptionObject = unhandledExceptionEventArgs.ExceptionObject as Exception;
if (exceptionObject == null) return;
var assembly = exceptionObject.TargetSite.DeclaringType.Assembly;
if (assembly == //your code)
{
//Do something
}
}
