我目前正在尝试针对 WSDL 编写一个小的 WCF-Routing 应用程序。但是当我尝试访问 SVC 文件时，出现以下错误：

合同需要 Session，但 Binding 'BasicHttpBinding' 不支持它或未正确配置以支持它。

由于我使用的是 SOAP12 的自定义绑定，因此我不理解此错误消息。我已经在这里搜索过了，但唯一的其他相关线程只有一条对我没有帮助的评论。（https://stackoverflow.com/questions/9896593/wcf-4-routing-service-and-configuration-error）

我的 web.config 如下：

<?xml version="1.0"?>

和 RoutingService.svc：

任何帮助和想法将不胜感激。
