minimize app to system tray - no icon appears

Question

i need to minimize app to system tray (see my icon there). But after starting the app, the icon dissapears from taskbar (that is fine) but i cannot see it in system tray (that is bad).

Where can be a mistake, please? PS: i am using WPF.

This is inner code of my event:

System.Windows.Forms.NotifyIcon notifyIcon = new System.Windows.Forms.NotifyIcon();
            if (WindowState.Minimized == this.WindowState)
            {
                notifyIcon.Visible = true;
                notifyIcon.BalloonTipText = "Radek app";
                notifyIcon.BalloonTipTitle = "Welcome Message";
                notifyIcon.BalloonTipIcon = System.Windows.Forms.ToolTipIcon.Info;                
                notifyIcon.ShowBalloonTip(3000);                
                this.ShowInTaskbar = false;
            }

            else if (WindowState.Normal == this.WindowState)
            {
                this.WindowState = WindowState.Normal;
                this.ShowInTaskbar = true;
                notifyIcon.Visible = false;
            }

you do the windowstate check immediately after defining the notifyicon? You might want to look at https://stackoverflow.com/questions/17674761/can-i-use-notifyicon-in-wpf for a proper example — Timothy Groote, Jun 13 '17 at 10:23

That Info icon is for the balloon, not the TrayIcon itself, you should add your image (I recommend 16x16px png file) to your application resources, then you can use it like:

var iconHandle = Properties.Resources.YourIconImage.GetHicon();
NotifyIcon.Icon = System.Drawing.Icon.FromHandle(iconHandle);

You need to set the Icon as shown below:

notifyIcon.Icon = new System.Drawing.Icon(Path to your Icon);
