Registering WCF service in Unity Container

I have a wcf service library that is hosted in a windows service. I need to intercept calls to Service methods. For this case it is suggested to register WCF into Unity container as can be seen in this link

I am trying to implement a similar approach by Unity.WCF assembly from Codeplex.I could not understand where to put my container configuration or bootstrapper in wcf service library(or windows service). There is not a solid sample (vs solution) provided.

My Windows Service Host

    private UnityServiceHost _serviceHost = null;
    private readonly UnityContainer _container;


    public Service() {
        InitializeComponent();
        _container = new UnityContainer();
        _container.AddNewExtension<Interception>();
        _container.RegisterType<ISecurityRepository, SecurityRepository>();
        _container.Configure<Interception>().SetDefaultInterceptorFor<ISecurityRepository>(new TransparentProxyInterceptor());
    }

    protected override void OnStart(string[] args) {

        //SecurityService
        if (_serviceHost != null) {

            _serviceHost.Close();
        } else {
            _serviceHost = new UnityServiceHost(_container, typeof(SecurityRepository));
            _serviceHost.Open();
        }

    }

    protected override void OnStop() {

        //SecurityService
        if (_serviceHost != null) {

            _serviceHost.Close();
            _serviceHost = null;
        }
    }

My Service Contract

[ServiceContract(SessionMode = SessionMode.Required)]
public interface ISecurityRepository
{

    [OperationContract(IsInitiating = true)]
    IList<vNavigationTree> GetNavigationTree(string ticket);

    [OperationContract(IsInitiating = true)]
    string GetSessionGuid(string userName, string IP, string machineName);
}

In this case it seems that interceptor does not work. Briefly what I need is a sample project in which the WCF Service is registered to DI container and the Service methods are intercepted.

I will try to explain what I tried to do more explicitly and how I managed to do it. I have a WPF application communicating with a database via WCF which means my app is divided roughly in two: client-side and server-side (WCF). I have wrapped the client-side into a Unity container via the UnityBootStrapper provided by PRISM. I need to wrap the server-side into another Unity container as well, in order to make Unity resolve the server-side dependencies.

My problem is solved by Unity.WCF (available as a Nuget package) which provides the UnityServiceHost class which can be used instead of ServiceHost. I guess this package is created in the way this post explains:
