تا اینجا هیچ گونه اعتبار سنجی انجام نشد. برای پیاده سازی اعتبار سنجی باید یک سری تنظیمات بر روی Binding و Hosting  سمت سرور و البته کلاینت بر قرار شود. فایل Program پروزه Service را باز نمایید و محتویات آن را به صورت زیر تغییر دهید:

 static void Main(string[] args)
        {
            ServiceHost host = new ServiceHost(typeof(BookService));

            var binding = new BasicHttpBinding();
            binding.Security = new BasicHttpSecurity();
            binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;

            host.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = System.ServiceModel.Security.UserNamePasswordValidationMode.Custom;

            host.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = new CustomUserNamePasswordValidator();               

            host.AddServiceEndpoint(typeof(IBookService), binding, "http://localhost/BookService");
            host.Open();


            Console.Write("BookService host");

            Console.ReadKey();
        }

 public class CustomUserNamePasswordValidator : UserNamePasswordValidator
    {
        public override void Validate(string userName, string password)
        {
            if (userName != "Masoud" || password != "Pakdel")
                throw new SecurityException("Incorrect userName or password");
        }
    }

این خطا از آن جا ناشی می‌شود که تنظیمات کلاینت و سرور از نظر امنیتی با هم تناسب ندارد. در نتیجه باید تنظیمات Binding کلاینت و سرور یکی شود. برای این کار کد زیر را به فایل Program سمت کلاینت اضافه می‌کنیم:

static void Main(string[] args)
        {
            Thread.Sleep(2000);
            BasicHttpBinding binding = new BasicHttpBinding();

            binding.Security = new BasicHttpSecurity();
            binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;            

            ChannelFactory<IBookService> channel = new ChannelFactory<IBookService>(binding, new EndpointAddress("http://localhost/BookService"));

            channel.Credentials.UserName.UserName = "WrongUserName";
            channel.Credentials.UserName.Password = "WrongPassword";
 



           Console.WriteLine("Count of book: {0}", channel.CreateChannel().GetCountOfBook());

            Console.ReadKey();
        }

channel.Credentials.UserName.UserName = "WrongUserName";
channel.Credentials.UserName.Password = "WrongPassword";

using (var transaction = new TransactionScope(TransactionScopeOption.Required,
 new TransactionOptions { IsolationLevel = IsolationLevel.ReadCommitted }))
{
    var database = new DatabaseContext();

    // DBC: BEGIN TRANSACTION

    var userA = database.Users.Find(1);
    var userB = database.Users.Find(2);
    userA.Name = "Admin";

    database.SaveChanges();

    userB.Age = 28;
    database.SaveChanges();


    // DBC: COMMIT TRANSACTION

    transaction.Complete();
}
