Operation ‘CreateProductCodeStock‘ of contract ‘IChileService‘ specifies multiple request body parameters to be serialized without any wrapper elements.
At most one body parameter can be serialized without wrapper elements.
Either remove the extra body parameters or set the BodyStyle property on the WebGetAttribute/WebInvokeAttribute to Wrapped.

It seems that you have created Proxy code using Add Service Reference dialog in VS, Since WCF REST Service is not based on SOAP message, so Add Service Reference doesn‘t support WCF REST Service fully, and the proxy code is missing [WebInvoke] attribute. Try creating proxy code using Add Web Reference in VS. Please check this similar post.

It seems you have created Proxy code using Add Service Reference dialog in VS.
VS ASR dialog doesn‘t support WCF REST fully, so, the proxy code is missing [WebInvoke] attribute.
Can you try adding [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped)] attribute on operations in client proxy?
是因为缺少了attribute导致的。
解决方法，不使用添加ServiceReference的方式获取。直接调用Service的library
