How to dispose the shared variable in vb.net

i am using shared object of Asterisk.NET Manager Variable, i assigned it in form load
and i dispose it in main form closing, My problem is after closing the application, application.exe keeps live in task manager, if i not initializing the shared object in form load there is no problem,

My code in form open

  Public Shared WithEvents objManager As Asterisk.NET.Manager.ManagerConnection

  Public Shared Sub ConnectAsterisk()
    Try
        objManager = New Asterisk.NET.Manager.ManagerConnection(ELASTIX_IP_ADDRESS, ASTERISK_PORT, ASTERISK_USER_NAME, ASTERISK_PASSWORD)
        objManager.Login()            
    Catch ex As Exception

    End Try
End Sub



 Private Sub frmMain_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
    AsteriskManager.objManager = Nothing
End Sub

can any one please help to do that

Thanks,
Senthil

I think the problem is not in the disposing of the ManagerConnection.
Asterisk.NET Manager doesn’t implement IDisposable.
You have to Logoff.

objManager.Logoff();

for vb.net would be

objManager.Logoff()

and then destroy the reference:

objManager = Nothing
