What needs to be done to have your .NET application show up in Window\'s system tray as icon?
And how do you handle mousebutton clicks on said icon?
You can add the NotifyIcon component from the toolbox onto your main form.
This has events such as MouseDoubleClick that you can use to handle various events.
Edit: You have to make sure that you set the Icon property to a valid .ico file if you want it to show up properly in the systray.
