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.

Answer 2

Change the Solution Configuration "Debug mode to Release mode" with X64 or X32 Solution platform. It will start work.

 public static NotifyIcon trayIcon;
 trayIcon = new NotifyIcon();
 trayIcon.Icon = new Icon("Images/Test.ico");
 trayIcon.Visible = true; trayIcon.Text=Path.GetFileNameWithoutExtension(AppDomain.CurrentDomain.FriendlyName);
 ContextMenu contextMenu1 = new ContextMenu();
contextMenu1.MenuItems.Add("Menu2", Menu2_Event);
contextMenu1.MenuItems.Add("Menu3", Menu3_event);
contextMenu1.MenuItems.Add("Exit", Close_Click);
trayIcon.ContextMenu = contextMenu1;
trayIcon.BalloonTipText = "Hi Test";
trayIcon.ShowBalloonTip(1000);

Answer 3

Neither of these solved my issue :(

But by accident I fixed it! My problem was I had my project configured for 32-bit on a 64-bit platform and for whatever reason they only show up when when I run the project for Any CPU (64-bit in this case)!!

Hopefully that helps some of you, it was a real mystery for me...

Answer 4

Found the problem - was simple: Quiet Hours was turned on in the notification center and this was preventing the balloon tips.

Answer 5

Turn off Focus Assist. If you are using second screen, turn off "When I'm duplicating my display" option. My settings is like that:
