xml - WCF 契约(Contract)第一个 : No methods are exposed

Question

我收到了带有一堆 XSD 的 WSDL，我正在使用它们来创建 WCF 服务。我正在使用 svcutil.exe 生成服务类，基本上一切正常 - 除了服务不公开任何方法。

从 svcutil 生成的 .cs 文件包含以下接口(interface):

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[System.ServiceModel.ServiceContractAttribute(Namespace="http://serviceplatformen.dk/xml/wsdl/soap11/DistributionService/1/port", ConfigurationName="DistributionReceiverWebServicePort")]
public interface DistributionReceiverWebServicePort
{

    [System.ServiceModel.OperationContractAttribute(Action="", ReplyAction="*")]
    [System.ServiceModel.FaultContractAttribute(typeof(serviceplatformen.dk.xml.wsdl.soap11.DistributionService._1.types.TransportkvitteringType), Action="", Name="TransportKvittering", Namespace="http://serviceplatformen.dk/xml/wsdl/soap11/DistributionService/1/types")]
    [System.ServiceModel.XmlSerializerFormatAttribute()]
    FordelingsobjektModtagResponse FordelingsobjektModtag(FordelingsobjektModtagRequest request);
}

有问题的类型如下所示:

[System.CodeDom.Compiler.GeneratedCodeAttribute("svcutil", "4.0.30319.33440")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://serviceplatformen.dk/xml/wsdl/soap11/DistributionService/1/types")]
public partial class ForretningskvitteringType
{

    private ForretningsValideringsKodeType forretningsValideringsKodeField;

    private string begrundelseField;

    private FejlType[] fejlListeField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute(Order=1)]
    public string Begrundelse
    {
        get
        {
            return this.begrundelseField;
        }
        set
        {
            this.begrundelseField = value;
        }
    }

    ...
}

我注意到没有任何类型是用 DataContract/DataMember 属性修饰的。这是必需的，还是类型的其他属性涵盖了它们？

我的服务(没有任何操作)暴露的 WSDL 是这样的:

</wsdl:definitions>

我想我遗漏了一些非常明显的东西，但是什么？

Answer 1

显然 svcutil 将 ReplyAction="*"添加到操作合约中，这导致了奇怪的行为。

删除 OperationContractAttribute 的规范后，问题就消失了。

[System.ServiceModel.ServiceContractAttribute(Namespace="http://tempuri.org/xml/wsdl/soap11/DistributionService/1/port", ConfigurationName="DistributionReceiverWebServicePort")]
public interface DistributionReceiverWebServicePort
{
    [System.ServiceModel.OperationContractAttribute(Action="")]
    [System.ServiceModel.FaultContractAttribute(typeof(TransportkvitteringType), Action="", Name="TransportKvittering", Namespace="http://tempuri.org/xml/wsdl/soap11/DistributionService/1/types")]
    [System.ServiceModel.XmlSerializerFormatAttribute()]
    FordelingsobjektModtagResponse FordelingsobjektModtag(FordelingsobjektModtagRequest request);
}
