我已经提到为什么找不到我的自定义 WCF 行为扩展元素类型？; 但以下是一个不同的问题

我有一个自定义的 BehaviorExtensionElement，如下所示。在运行服务时，它的构造函数被调用。但是它不调用 CreateBehavior() 方法。因此我的 IEndpointBehavior 没有被构建。

该服务工作正常，没有任何例外。

知道为什么CreateBehavior()不调用该方法吗？

注意：我正在从Visual Studio 2010.

配置

  <endpointBehaviors>
    <behavior name="EndpointBehavior">
      <XMessageValidator validateRequest="True" validateReply="true" validateWSE="true">
      </XMessageValidator>
    </behavior>
  </endpointBehaviors>


 //Other config entries

<extensions>
  <behaviorExtensions>
    <add name="XMessageValidator" type="MessageInspectorLibrary.ValidationBehaviorExtensionElement, MessageInspectors, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
  </behaviorExtensions>
</extensions>

行为扩展元素

public class ValidationBehaviorExtensionElement : BehaviorExtensionElement
{
    public ValidationBehaviorExtensionElement()
    {
        //Constructor
    }

    public override Type BehaviorType 
    { 
        get
        {
            return typeof(MessageValidationBehavior);
        } 
    }

    protected override object CreateBehavior()
    {
        throw new Exception("My CreateBehavior");
        return null;

    }

    [ConfigurationProperty("validateRequest", DefaultValue = false, IsRequired = false)]
    public bool ValidateRequest
    {
        get { return (bool)base["validateRequest"]; }
        set { base["validateRequest"] = value; }
    }

    [ConfigurationProperty("validateReply", DefaultValue = false, IsRequired = false)]
    public bool ValidateReply
    {
        get { return (bool)base["validateReply"]; }
        set { base["validateReply"] = value; }
    }

    [ConfigurationProperty("validateWSE", DefaultValue = false, IsRequired = false)]
    public bool ValidateWSE
    {
        get { return (bool)base["validateWSE"]; }
        set { base["validateWSE"] = value; }
    }

}

端点行为

public class MessageValidationBehavior : IEndpointBehavior
{
    XmlSchemaSet schemaSet; 
    bool validateRequest; 
    bool validateReply;
    bool validateWSE;

    public MessageValidationBehavior(XmlSchemaSet schemaSet, bool inspectRequest, bool inspectReply, bool inspectWSE)
    {
        this.schemaSet = schemaSet;
        this.validateReply = inspectReply;
        this.validateRequest = inspectRequest;
        this.validateWSE = inspectWSE;

        throw new Exception("My MessageValidationBehavior");
    }


    #region IEndpointBehavior Members

    public void AddBindingParameters(ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime)
    {
        ValidationMessageInspector inspector = new ValidationMessageInspector(schemaSet, validateRequest, validateReply, validateWSE, true);
        clientRuntime.MessageInspectors.Add(inspector);
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
    {
        ValidationMessageInspector inspector = new ValidationMessageInspector(schemaSet, validateRequest, validateReply, validateWSE, false);
        endpointDispatcher.DispatchRuntime.MessageInspectors.Add(inspector);
    }

    public void Validate(ServiceEndpoint endpoint)
    {
    }

    #endregion
}

Note: As I said in the question, the service gives proper response message even without the following change. Also, the ValidationBehaviorExtensionElement class was getting called.

Solution

The CreateBehavior() is called when I made the service name correct – i.e, namespace.servicename.

What I understand is - BehaviorExtension is created irrespective of the service name. But EndPointBehavior is created only if the service name is proper. More details are welcome if you have some idea/reference on this.

enter image description here

Following is the complete serviceModel config

<system.serviceModel>

<services>

  <service
          name="WcfServiceApp001.Service1"
          behaviorConfiguration="InternalPayrollBehavior">
    <endpoint address="" binding="basicHttpBinding"
              behaviorConfiguration="EndpointBehavior"
              contract="WcfServiceApp001.IService1"
              />
  </service>
</services>

<behaviors>
  <serviceBehaviors>
    <behavior name="InternalPayrollBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>

  <endpointBehaviors>
    <behavior name="EndpointBehavior">
      <XMessageValidator validateRequest="True" validateReply="true" validateWSE="true">
      </XMessageValidator>
    </behavior>
  </endpointBehaviors>
</behaviors>

<extensions>
  <behaviorExtensions>
    <add name="XMessageValidator" type="MessageInspectorLibrary.ValidationBehaviorExtensionElement, MessageInspectors, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
  </behaviorExtensions>
</extensions>

<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
</system.serviceModel>

我建议你把你的封装在behaviors node

 <behaviors>
  ....
  <endpointBehaviors>
    <behavior name="EndpointBehavior">
      <XMessageValidator validateRequest="True" validateReply="true" validateWSE="true">
      </XMessageValidator>
    </behavior>
  </endpointBehaviors>
  ....
 </behaviors>
