ShowBalloonTip Not Working

Question

On Windows 10, the ShowBalloonTip method of NotifyIcon NEVER shows the balloon tip. This would appear to have something to do with Windows itself.<

Answer 1

On my computer with Windows 10 version 1803, go to Settings > System > Notifications & actions, and turn on "Get notifications from apps and other senders". The ballontips from my WPF app will show up.
