    Public Overrides Function InitializeLifetimeService() As Object
        Dim lease As ILease = CType(MyBase.InitializeLifetimeService(), ILease)
        If lease.CurrentState = LeaseState.Initial Then
            lease.InitialLeaseTime = TimeSpan.FromMinutes(1)
            lease.SponsorshipTimeout = TimeSpan.FromMinutes(2)
            lease.RenewOnCallTime = TimeSpan.FromSeconds(2)
        End If
        Return lease
    End Function


    Public Shared Sub Main()  
    ' The main thread processing is here.

    {
        ILease lease = (ILease)(super.InitializeLifetimeService());
        if (lease.get_CurrentState().Equals(LeaseState.Initial)) {
            lease.set_InitialLeaseTime(TimeSpan.FromMinutes(1));
            lease.set_SponsorshipTimeout(TimeSpan.FromMinutes(2));
