And in the test page's load even I am creating the Service proxy in the following way
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim factory As ChannelFactory(Of IStayAtWorkService)
        'GetMessages(New Guid("b14bc077-f1df-457c-9f7e-7cb9e0bc1cf3"))

        Try
                factory = ServiceFactory(Of IStayAtWorkService).GetBasicHttpChannelForService _
            (ConfigurationManager.AppSettings("StayAtWorkServiceAddress"))
            Dim sawService As IStayAtWorkService = factory.CreateChannel()

            Dim inputFileBytes() As Byte
            Dim inputFile As String = ConfigurationManager.AppSettings("InputFiles")
            Using fstream = New FileStream(inputFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)
                Using br As BinaryReader = New BinaryReader(fstream)
                    inputFileBytes = br.ReadBytes(fstream.Length)
                    br.Close()
                End Using
                fstream.Close()

            Dim fUpload As New RequestFile()

            fUpload.RequestId = 2
            Dim d = sawService.SaveRequestFile(fUpload)
            GridView1.DataSource = d
            GridView1.DataBind()
        Catch ex As Exception
        Finally
            ServiceFactory(Of IStayAtWorkService).CloseChannelFactory(factory)
        End Try
End Sub
