Form_Load exception troubleshooting

Don't put code in Form_Load event if possible, silent errors will creep in when you are running inside Visual Studio. Error will manifest only when the EXE is run directly

private void Form1_Load(object sender, EventArgs e)
{
    int n = 0;
    MessageBox.Show((7 / n).ToString()); // won't throw an Exception when run inside VS
}

private void Form1_Shown(object sender, EventArgs e)
{
    int n = 0;
    MessageBox.Show((7 / n).ToString()); // will throw an exception, regardless of where it is run
}
