2) Also, in Program.Application_ThreadException() logs only System.Threading.ThreadExceptionEventArgs, not the exception.
Should pass e.Exception to NLog.Logger.Fatal:
private static void Application_ThreadException (object sender, ThreadExceptionEventArgs e)
{
_logger.Fatal(e.Exception);
Similarly in Program.CurrentDomain_UnhandledException():
private static void CurrentDomain_UnhandledException (object sender, UnhandledExceptionEventArgs e)
{
_logger.Fatal(e.ExceptionObject);
3) A small cosmetic issue – text of SearchDialog.buttonRegexHelper button is cut off:
