Dim baseAddress As New Uri("http://localhost:8001/Simple")
Dim serviceHost As New ServiceHost(GetType(CalculatorService), baseAddress)

serviceHost.AddServiceEndpoint(GetType(ICalculator), New WSHttpBinding(), "CalculatorServiceObject")

備註

使用 TransactionIsolationLevel 屬性，即可取得或設定服務的發送器所建立之新異動的預設隔離等級。

只有在 ChannelDispatcher 的執行個體處於 Created 狀態時才可以設定這個屬性，因為這是唯一同時處於可變動且尚未處置的狀態。
