WCF - How to pass service class constructor parameter when initializing Service Host(TypeOf(Service-Class))

Question

I have WCF service class 'MusicServiceManager' with the constructor that takes the parameter of IAppAmbientState. I need to pass parameter value to MusicServiceManager constructor at time initializing Service Host. I don't want singleton implementation for IAppAmbientState.

Service Contract

[ServiceContract]
public interface IAlbumService
{
    [OperationContract]
    string TestMessage();

    [OperationContract]
    IEnumerable<AlbumData> GetAlbums();

    [OperationContract(Name = "GetAlbumByID")]
    AlbumData GetAlbum(Guid ID);

    [OperationContract(Name = "GetAlbumByName")]
    AlbumData GetAlbum(string name);
}

AppAmbientState

public class AppAmbientState : IAppAmbientState
{
    public IContainer ServiceContainer { get; }

    public AppAmbientState(
        IContainer container  // autofac DIC container
        )
    {
        ServiceContainer = container;
    }
}

MusicServiceManager

public class MusicServicesManager : IAlbumService
{
    private readonly IAppAmbientState _appAmbientState;
   
    public MusicServicesManager(IAppAmbientState appAmbientState)
    {
        this._appAmbientState= appAmbientState;         
    }

    public AlbumData GetAlbum(Guid ID)
    {
        throw new NotImplementedException();
    }

Service Host Configuration Class

public class ServiceHostConfiguration : IServiceHostConfiguration
{
    private readonly ServiceHost hostMusicServiceManager;

    public ServiceHostConfiguration()
    {
        var container = ContainerConfiguration.Configure();

        AppAmbientState AppAmbientStateInstance = new AppAmbientState(container);
        // need help here... MusicServiceManager(AppAmbientStateInstance)???? 
        // ideally I don't want to define my base address in class

        this.hostMusicServiceManager = new ServiceHost(typeof(MusicServicesManager));
    }

    public void InitializeService()
    {
        try
        {
            this.hostMusicServiceManager.Open();
            Console.WriteLine("App Web Services Started. Press [Enter] To Exit  ");
        }
        catch(Exception exp)
        {
            Console.WriteLine("App Web Services Could Not Start::  ", exp);
        }
        
    }

    public void CloseService()
    {
        this.hostMusicServiceManager.Close();
    }
}

Autofac DI Container

public static class ContainerConfiguration
{
    public static IContainer Configure()
    {
        var builder = new ContainerBuilder();
        
        //Application Configuration
        builder.RegisterType<Application>().As<IApplication>();
        builder.RegisterType<ServiceHostConfiguration>().As<IServiceHostConfiguration>();
        builder.RegisterType<AppAmbientState>().As<IAppAmbientState>();
        builder.RegisterType<MusicServicesManager>().As<IAlbumService>();

Here is my Demo:

This is the project directory:

Program.cs:

using Autofac;
using Autofac.Integration.Wcf;
using System;
using System.ServiceModel;
using System.ServiceModel.Description;

namespace AutofacTest
{
    class Program
    {
        static void Main(string[] args)
        {
            ContainerBuilder builder = new ContainerBuilder();
            builder.RegisterType<Logger>().As<ILogger>();
            builder.RegisterType<Service>();

            using (IContainer container = builder.Build())
            {
                
                ServiceHost host = new ServiceHost(typeof(Service));
                host.AddDependencyInjectionBehavior<Service>(container);
                host.Open();
                Console.WriteLine("The host has been opened.");
                Console.ReadLine();
                host.Close();
              
            }
        }
    }
    [ServiceContract]
    public interface IService
    {
        [OperationContract]
        string Test();
    }

    public interface ILogger
    {
    }

    public class Service : IService
    {
        private readonly ILogger logger;

        
        public Service(ILogger logger)
        {
            this.logger = logger;
        }

        public string Test()
        {
            return "TEst1";
        }
    }

    public class Logger : ILogger
    {

    }
}

App.config:

<?xml version="1.0" encoding="utf-8"?>

                    </baseAddresses>
                </host>
            </service>

                    <serviceMetadata httpGetEnabled="true" />
                </behavior>
