c# - 警告 : The optional WSDL extension element 'body' from namespace 'http://schemas.xmlsoap.org/wsdl/soap/' was not handled

我正在使用 Visual Studio 2010、.Net4、Silverlight(4.0.50826.0)。

我创建了一个 WCF 服务,我正在尝试使用 SlSvcUtil 创建一个代理,例如:

SlSvcUtil.exe /serializer:DataContractSerializer http://192.128.09.26:8080/Server?wsdl /out:C:\Projets\Client\dService.cs /config:C:\Projets\Client\ServiceReferences.ClientConfig

当我添加一些带有客户类型的方法并且它们也有一些属性时,我得到了这个消息:

Warning: The optional WSDL extension element 'body' from namespace 'http://schemas.xmlsoap.org/wsdl/soap/' was not handled.

XPath: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:binding[@ name='BasicHttpBinding_IService']/wsdl:operation[@name='GetDefinitionsHavingFre']/wsdl:output

如果我忽略警告并尝试使用该类,那么在调用任何方法时都会出现 NullException 错误。

如果我更改选项 /Serializer:XmlSerializer 或任何其他选项它可能会正确创建代理但我在 visual studio 中得到很多空引用,因此有必要添加正确的 .

如果我添加:来自 Silverlight 的 System.ServiceModel - xmlserializerformatattribute 不存在 System.ServiceModel 来自 .NET - ChannelBase 不存在

如果我没有使用客户方法,我的服务就可以正常工作,所以我的问题是在使用客户类型或带有属性的方法时,silverlight 有一些限制吗?

有人知道可以做些什么来解决这个问题吗?

谢谢,

最佳答案

我发现了问题。

在使用 SlSvcUtil 创建代理并在我的 Visual Studio 项目中添加 .cs 后,我得到了这个错误:

The type or namespace name 'XmlSerializerFormatAttributeAttribute' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?)

首先,我尝试将 System.Service.Model 从 Silverlight 版本更改为 .Net 版本,但我遇到了其他错误。

所以我找到了需要的地方,在SlSvcUtil中使用/serializer:DataContractSerializer;之后这个错误就解决了。但是,当生成代理时,我收到了 WSDL 警告。

解决方案

  1. 我使用以下命令创建了代理:

    SlSvcUtil.exe http://192.128.09.26:8080/Server /out:C:\Projets\Client\dService.cs /config:C:\Projets\Client\ServiceReferences.ClientConfig

    然后我在 Visual Studio 中得到了这个错误:

    The type or namespace name 'XmlSerializerFormatAttributeAttribute' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?)

  2. 我添加了以下 dll:

    • System.Xml.Serialization.dll -(运行时版本 v2.0.50727)

结论

Visual Studio 无法在 ServiceModel.dll 中找到引用,而 ServiceModel 在那里,所以我从没想过要添加另一个 .dll,因为已经添加了正确的 dll。

就在昨天,我尝试添加 System.Xml.Serialization.dll,现在一切正常。
