Nice series, thanks!

Question about the timer example: Is it best practice to add on .Dispose to the subscriber to have it cleanup (assuming yes), or will this happen automatically when the method completes. (showed example in vb)

Observable
    .Timer(TimeSpan.FromMilliseconds(intervalMs))
    .ObserveOn(Threading.SynchronizationContext.Current)
    .Subscribe(Function(x) StatusBar.Panels("statusPanelHeartbeat").Visible = False,
               Function(x) StatusBar.Panels("statusPanelHeartbeat").Visible = False)
    .Dispose()

Thank you.

It was necessary to remove the .Dispose in this case to make it work correctly.
