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

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

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...

Change the Solution Configuration &quot;Debug mode to Release mode&quot; with X64 or X32 Solution platform. It will start work.
<pre><code> public static NotifyIcon trayIcon;
 trayIcon = new NotifyIcon();
 trayIcon.Icon = new Icon(&quot;Images/Test.ico&quot;);
 trayIcon.Visible = true; trayIcon.Text=Path.GetFileNameWithoutExtension(AppDomain.CurrentDomain.FriendlyName);
 ContextMenu contextMenu1 = new ContextMenu();
contextMenu1.MenuItems.Add(&quot;Menu2&quot;, Menu2_Event);
contextMenu1.MenuItems.Add(&quot;Menu3&quot;, Menu3_event);
contextMenu1.MenuItems.Add(&quot;Exit&quot;, Close_Click);
trayIcon.ContextMenu = contextMenu1;
trayIcon.BalloonTipText = &quot;Hi Test&quot;;
trayIcon.ShowBalloonTip(1000);

Just for reference, as @rmirabelle wrote in the question &quot;My NotifyIcon is VISIBLE&quot;. This is actually important.
If the notification icon is not visible in the systray, the <code>BalloonTips</code> won't show up either.
Possible sources for invisibility are:
<ul>
<li>Visible property = false</li>
<li>No icon is set for the <code>NotifyIcon</code> object</li>
</ul>

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

If I go to <code>Settings &gt; System &gt; Notifications &amp; actions</code> > and find my running app (<code>vshost32.exe</code> in debug mode) and click on it, then turn on <code>Show notifications in the action center</code>, I can clearly see the balloon tip messages being added to the notifications, but never a balloon tip.

I assume this is a problem with Windows 10.

My <code>NotifyIcon</code> is <code>VISIBLE</code>

<pre><code>my_icon.ShowBalloonTip("Title", "Message", BalloonIcon.Info);
</code></pre>

在Windows10上，NotifyIcon的ShowBalloonTip方法从不显示气球提示。这似乎与Windows本身有关。如果我转到Settings > System > Notifications & actions >，找到我正在运行的应用程序(调试模式下的vshost32.exe)并点击它，然后打开Show notifications in the action center，我可以清
