我为以下所有内容设置了一致的命名空间 (http://somenamespace.com/2012/10/)：

  1. 服务契约命名空间
  2. 服务命名空间
  3. 数据契约命名空间
  4. 绑定命名空间

但是，我在服务日志 (.svclog) 文件中收到此错误。有人可以启发我吗？我已经咨询了几个网站，但无济于事。

这是一个很好的参考：http ://social.msdn.microsoft.com/Forums/en-US/wcf/thread/ee11d86f-f25c-4284-8f51-b1f035346cb3/

从堆栈跟踪来看，我怀疑您的合同中某处有一个派生类，特别是在 PaymentType、PaymentTypeBase 周围。

尝试使用KnownType属性装饰您的顶级 DataContract 。这可以帮助反序列化器了解反序列化响应的类型。

您可能刚刚打开了“处理 OO 主体”但“使用服务”的蠕虫罐头。

在某个地方，您必须“付钱给提琴手”关于您将实际使用的抽象类的哪个具体，也就是通过服务线传递。

这是一种方法：（这种方法使用反射来找出具体情况）

http://ashgeek.blogspot.com/2011/02/wcf-serialization-dynamically-add.html

这是另一个：（这个使用一个小文本文件来列出具体内容）

http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/6b70e9f4-52bc-4fa9-a0ff-c0859e041e85/

最后：服务喜欢具体，它们不喜欢抽象类或接口。

糟糕的是，多年来我们一直被告知要对接口（或抽象类）进行编程，而不是对具体的实现进行编程。
