System.ArgumentException:未定义"http://somenamespace.com/2012/10/"命名空间

Question

我已经为以下所有设置了一致的命名空间(http://somenamespace.com/2012/10/):

1. Service Contract名称空间
2. 服务命名空间
3. Data Contract命名空间
4. 绑定命名空间

但是我在服务日志(.svclog)文件上收到此错误.有人可以开导我这个吗？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/

从堆栈跟踪判断,我怀疑你的合同中有一个派生类,特别是在PaymentType,PaymentTypeBase附近.

尝试使用KnownType属性装饰顶级DataContract .这可以帮助解串器知道要对响应进行反序列化的类型.
