You can use the NotifyIcon namespace from System.Windows.Forms as follows:
class Test { private readonly NotifyIcon _notifyIcon; public Test() { _notifyIcon = new NotifyIcon();
This should work with the .NET Framework 1.1. See this MSDN page for ShowBalloonTip options.
As I found out, the first parameter ShowBalloonTip (in my example, which will be 3000 milliseconds) is generously ignored. Comments are welcome;)
