Why isn't my NotifyIcon showing up?
There are not that many ways to fumble a NotifyIcon
. Except one, if you forget to set its Icon property then it will never show up. Ought to raise an exception but that was overlooked.
If you are using Windows 10 go to Settings > System > Notifications & actions and make sure notifications are switched on for your app. Also make sure 'quiet hours' is not on.
