I notice the same issue we had with NotifyIcon Balloon tips under
C/C++ is persistent with the .NET NotifyIcon class.

At issue is, the balloon tip does not work or rather the time to close
does not work under certain OS versions. What happens the tip pops up
but doesn't go away after the time (expires).

Does anyone know if this has been resolved? or some method is used
under .NET?

In my C/C++ code, I used a timer to disable the balloon tip so that it
works the same across all Windows OSes.

So I did the same here, by adding a BallonTipTimer and a countdown
like so:

Public Class Form1

Private BalloonTipTime As Integer = 5 ' seconds

Private Sub Form1_Load( _
ByVal sender As Object, _
ByVal e As System.EventArgs) Handles Me.Load
NotifyIcon1.ShowBalloonTip(BalloonTipIntTime * 1000)
BalloonTipTimer.Start()
End Sub

Private Sub BalloonTipTimer_Tick( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles BalloonTipTimer.Tick

BalloonTipInterval -= 1
If (BalloonTipTime <= 0) Then
BalloonTipTimer.Stop()
NotifyIcon1.Visible = False ' hide icon
NotifyIcon1.Visible = True ' reshow icon without tip
End If
End Sub
End Class

Is there an alternative method under .NET? This is the sort of thing
I was hoping to eliminate by using .NET more.

This is by design. The ballon go away in the given time if there is an
user present. Detected is this by mouse movement and keyboard input.
