WPF WCF produce data as service and WPF consume data as client periodically

1.In WCF,Add WCF Service,BookService

 

2.

//D:\C\WcfService1\WcfService1\Book.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace WcfService1
{
    public class Book
    {
        public long Id { get; set; }
        public string Name { get; set; }
        public string Abstract { get; set;  }
        public string Author { get; set; }
        public string ISBN { get; set; }
        public string Comment { get; set;  }
        public string Content { get; set; }
        public string Summary {  get; set; }
        public string Title {  get; set; }
        public string Topic {  get; set; }
    }
}

//D:\C\WcfService1\WcfService1\IBookService.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace WcfService1
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IBookService" in both code and config file together.
    [ServiceContract]
    public interface IBookService
    {
        [OperationContract]
        long Get_Increment_Id();

        [OperationContract]
        List<Book> Get_Books_List(int cnt = 1000000);
    }
}

//D:\C\WcfService1\WcfService1\BookService.svc.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.Threading;

namespace WcfService1
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "BookService" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select BookService.svc or BookService.svc.cs at the Solution Explorer and start debugging.
    public class BookService : IBookService
    {
        long id = 0;

        public List<Book> Get_Books_List(int cnt = 100)
        {
            List<Book> booksList = new List<Book>();
            for(int i=0;i<cnt;i++)
            {
                id = Get_Increment_Id();
                booksList.Add(new Book()
                {
                    Id =id,
                    Name=$"Name_{id}",
                    ISBN=$"ISBN_{id}_{Guid.NewGuid():N}",
                    Author=$"Author_{id}",
                    Abstract=$"Abstract_{id}",
                    Comment=$"Comment_{id}",
                    Content=$"Content_{id}",
                    Summary=$"Summary_{id}",
                    Title=$"Title_{id}",
                    Topic=$"Topic_{id}"
                });
            }
            return booksList;
        }

        public long Get_Increment_Id()
        {
            return Interlocked.Increment(ref id);
        }
    }
}

4.In WPF,Add project reference of WCF, dll file;

5.
