和你一样,你将需要一个习俗服务机构,用于创建你的服务。 与此类似:

public class SessionPerCallServiceHostFactory : ServiceHostFactory
{
    public SessionPerCallServiceHostFactory()
    {
    }

    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
    {
        return new SessionPerCallServiceHost(serviceType, baseAddresses);
    }
}

你们还需要一个负责创造必要服务的服务机构:

public class SessionPerCallServiceHost : ServiceHost
{
    public SessionPerCallServiceHost()
    {
    }

    public SessionPerCallServiceHost(Type serviceType, params Uri[] baseAddresses)
    : base(serviceType, baseAddresses)
    {
    }

    protected override void OnOpening()
    {
        Description.Behaviors.Add(new SessionPerCallServiceBehavior());
        base.OnOpening();
    }

}

采用惯用的ISERBehavior,能够提供用来制造服务的提供人:

public class SessionPerCallServiceBehavior : 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 SessionPerCallInstanceProvider(serviceDescription.ServiceType);
                }
            }
        }
    }

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

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

}

最后,将允许你利用国际奥委会在所请求的服务场合注入你所希望的任何东西的助手:

public class SessionPerCallInstanceProvider : IInstanceProvider
{
    private readonly Type _serviceType;

    public SessionPerCallInstanceProvider(Type serviceType)
    {
        _serviceType = serviceType;
    }

    public object GetInstance(InstanceContext instanceContext, System.ServiceModel.Channels.Message message)
    {
        //I m creating it without any tricks but you could use your IoC container here
        return Activator.CreateInstance(_serviceType);
    }

    public object GetInstance(InstanceContext instanceContext)
    {
        return GetInstance(instanceContext, null);
    }

    public void ReleaseInstance(System.ServiceModel.InstanceContext instanceContext, object instance)
    {

    }
}

希望!
