Al agregar una extensión de comportamiento de wcf personalizada se produce una excepción ConfigurationErrorsException

Question

Deseo agregar una extensión de comportamiento para que mis clases de servicio se instanciarán con Ninject. Creé una clase que hereda de BehaviorExtensionElement y la registré en mi App.config. No puedo ver nada obvio que me falta, sin embargo, en el inicio de este se lanza:

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 

Aquí es mi 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> 

Aquí es mi clase de comportamiento:

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(); 
    } 

}

Resulta que el nombre del tipo debe ser exactamente equivalente a typeof(DependencyInjectionServiceBehavior).AssemblyQualifiedName. Mi entendimiento anterior era que no se suponía que hubiera ningún espacio en el nombre de tipo completo, que resultó ser incorrecto.
