我正在使用已消耗的Web服务，并已在Visual Studio中自动生成代码。
服务就是这样的：https://www.onvif.org/onvif/ver10/events/wsdl/event-vs.wsdl
这部分代码可以正常运行，并且可以在Windows 10上正常运行，但是在Ubuntu中的Mono 5.18.0.225上运行相同的EXE时，会发生以下异常。
我可以成功连接到SOAP服务器（IP CCTV摄像机），并且许多命令都可以正常运行。但是，当我尝试订阅事件时，会收到错误消息：
Unhandled Exception:
System.InvalidOperationException: There was an error generating the XML document. ---> System.ArgumentException: The empty string '' is not a valid local name.
此函数的第三行似乎是发生错误的地方，但是我无法进一步调试并查看内部实际运行的代码是什么（因为我假设这是内部.NET代码）。
public Onvif.OnvifEventServiceReference.SubscribeResponse
Subscribe(Onvif.OnvifEventServiceReference.Subscribe Subscribe1) {
Onvif.OnvifEventServiceReference.SubscribeRequest inValue = new
Onvif.OnvifEventServiceReference.SubscribeRequest();
inValue.Subscribe = Subscribe1;
Onvif.OnvifEventServiceReference.SubscribeResponse1 retVal = ((Onvif.OnvifEventServiceReference.NotificationProducer)(this)).Subscribe(inValue);
return retVal.SubscribeResponse;
}
消息永远不会发送到网络，因为应用程序会在发生异常之前引发异常。

我正在寻找有关调试位置的建议-好像是Xml WriteStartElement函数引发错误-也许localname变量传递不正确。但是即使我逐步执行，也无法看到，因为这都是WCF的内部代码。
任何指针表示赞赏。
