使用 WCF 导入 WSDL 时出现问题

Question

我正在尝试使用 WCF 为我公司的合作伙伴之一提供的 Web 服务导入 WSDL。 Web 服务是用 Java 编写的。我收到此错误：

警告：无法导入操作 getUnits 中名为 FooException 的错误。不支持 WSDL，故障消息部分必须引用元素。该错误消息未引用元素。如果您具有 WSDL 文档的编辑权限，则可以通过使用“element”属性引用架构元素来解决该问题。

好吧，实际上不是错误，但在生成的代码中 FooException 被忽略了。 FooException 包含我真正需要的错误代码。

我缩短了 WSDL，只保留了其中一种方法。我还重命名了一些东西（比如例外）。

我尝试将 FooException 的消息部分中的“type”更改为“element”，但这会导致错误。我还需要做什么？
