While Tray Icons (and applications that use ONLY TrayIcons as their UI) are a major part of our lives, there's limited support in WinForms (2.0) for them without resorting to P/Invoke and vestigial MainForms who only call this.Hide().NotifyIcon should be extended to support BalloonHelp. Hans Blomme's now-famous extended version of NotifyIcon is the canonical example. It still works under 2.0, but the 2.0 addition of the ContextMenuStrip makes it a little tricky. His free stuff could be integrated into the 2.0 NotifyIcon easily, adding a powerful (and missing) feature to 2.0 WinForms. Additionally, there should be a way for a Form to startup hidden to avoid the flash of the form before it calls this.Hide(), deferring to it's NotifyIcon.
Help us all out and vote to get this omission fixed in Whidbey.
UPDATE: Some Reflectoring has confirmed that has in fact been fixed in the December CTP! All is as it should be. Thanks to Chris Sells and Scott Swigart.
