如何在不更改后绑定的情况下从WCF服务引用WCF客户端？

我有一个C＃WCF服务，我需要引用另一个Web服务。旧服务是用Visual Basic编写的，不是WCF。

前者应该弃用后者，但是旧服务中有一些方法很复杂。因此，我想从新服务中调用旧服务中的方法。

为避免命名混乱，我想将旧服务的包装封装在一个单独的项目中，该项目从新服务中引用。但是，当我尝试从新服务项目调用包装器时，新服务引发了InvalidSoapOperation。当我从包装项目本身调用旧服务时，不会引发此异常。

通常，我会将旧服务的绑定从包装项目复制并粘贴到新项目，但是由于合同的相似性，我很犹豫。

有没有办法通过包装项目“间接”引用旧服务，以使新服务项目不直接与旧服务耦合？

编辑：堆栈跟踪如下：

包装项目中的App.Config：

<system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="OldServiceSoap" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost/OldService/OldService.asmx"
                binding="basicHttpBinding" bindingConfiguration="LogOrderSoap"
                contract="OldService.OldServiceSoap" name="OldServiceSoap"/>
        </client>
</system.serviceModel>
