Answer 1

You should be able to catch everything with this

    [STAThread]
    public static void Main()
    {
        // let IDE to handle exceptions
        if (System.Diagnostics.Debugger.IsAttached)
            Run();
        else
            try
            {
                Application.ThreadException += Application_ThreadException;
                Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
                AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
                Run();
            }
            catch (Exception e)
            {
                // catch exceptions outside of Application.Run
                UnhandledException(e);
            }
    }

    private static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
    {
        // catch non-ui exceptions
        UnhandledException(e.ExceptionObject as Exception);
    }

    private static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)
    {
        // catch ui exceptions
        UnhandledException(e.Exception);
    }

    private static void UnhandledException(Exception e)
    {
        try
        {
            // here we restart app
        }
        catch
        {
            // if we are here - things are really really bad
        }
    }
