添加自定義wcf行爲擴展導致ConfigurationErrorsException

Question

我想添加行爲擴展，以便我的服務類將使用Ninject實例化。我創建了一個繼承自BehaviorExtensionElement的類並將其註冊到我的App.config中。我什麼都看不到明顯的我失蹤，但在啓動時，這是拋出：

System.Configuration.ConfigurationErrorsException: An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element TestExtension cannot be added to this element. Verify that the extension is registered in the extension collection at system.serviceModel/extensions/behaviorExtensions. 
Parameter name: element (...\MyAssembly.dll.config line 42) ---> 
System.ArgumentException: Extension element TestExtension cannot be added to this element. 
Verify that the extension is registered in the extension collection at system.serviceModel/extensions/behaviorExtensions. 
Parameter name: element 

這裏是我的App.config：

<system.serviceModel> 
<extensions> 
    <behaviorExtensions> 
    <add name="TestExtension" type="Mynamespace.DependencyInjectionServiceBehavior,MyAssembly,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null" /> 
    </behaviorExtensions> 
</extensions> 
<behaviors> 
    <serviceBehaviors> 
    <behavior name="MyServiceBehavior"> 
     <TestExtension/> 
    </behavior> 
    </serviceBehaviors> 
</behaviors> 

這裏是我的行爲類：

public class DependencyInjectionServiceBehavior : BehaviorExtensionElement, IServiceBehavior 
{ 
    public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase) 
    { 
     foreach (ChannelDispatcherBase cdb in serviceHostBase.ChannelDispatchers) 
     { 
      ChannelDispatcher cd = cdb as ChannelDispatcher; 
      if (cd != null) 
      { 
       foreach (EndpointDispatcher ed in cd.Endpoints) 
       { 
        ed.DispatchRuntime.InstanceProvider = 
         new DependencyInjectionInstanceProvider(serviceDescription.ServiceType); 
       } 
      } 
     } 
    } 

    public void Validate(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase) 
    { 
    } 

    public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, 
     Collection<ServiceEndpoint> endpoints, BindingParameterCollection bindingParameters) 
    { 
    } 

    public override Type BehaviorType 
    { 
     get { return this.GetType(); } 
    } 

    protected override object CreateBehavior() 
    { 
     return new DependencyInjectionServiceBehavior(); 
    } 

}

原來的類型名稱需要與typeof(DependencyInjectionServiceBehavior).AssemblyQualifiedName完全相同。我之前的理解是，在完全限定類型名稱中不應該有任何空格，結果是錯誤的。
