Xamarin.ios 将wsdl导入monodevelop时出错

我在将wsdl导入mono develop时遇到问题

此wsdl和xsd实现在VisualStudio下完美地工作，但无法导入mono develop

我还针对几个wsdl验证站点进行了检查，它们都通过了

我使用的过程是创建一个项目，然后“添加web引用”。然后我选择.NET2.0作为wsdl的类型。然后我粘贴到wsdl的链接。然后点击“跳到”

然后我得到下面列出的错误。这使我无法完成对产品的评估，您能提供的任何帮助都是有益的

wsdl文件位于此处： ftp.echelon.com/fae/na/outgoing/GDahl/wsdlissue/v4.0.zip

所讨论的wsdl文件是ilon100.wsdl
