This App.config is generating the following Exception:

Unrecognized attribute 'type'. Note that attribute names are case-sensitive.

My Source code is as follows:

using System;
using System.Collections.Generic;
using System.Text;

namespace DerivativesCalculator
{
    public class Calculator
    {
        public decimal CalculateDerivative(
          string[] symbols,
          decimal[] parameters,
          string[] functions)
        {
            return (decimal)(System.DateTime.Now.Millisecond);
        }
    }
}

using System;
using System.Collections.Generic;
using System.Text;

using DerivativesCalculatorService;
using DerivativesCalculator;

namespace DerivativesCalculator
{
    public class DerivativesCalculatorServiceType : IDerivativesCalculator
    {
        decimal IDerivativesCalculator.CalculateDerivative(
        string[] symbols,
        decimal[] parameters,
        string[] functions)
        {
            return new Calculator().CalculateDerivative(
                symbols, parameters, functions);

        }

        void IDerivativesCalculator.DoNothing()
        {
            return;
        }
    }
}

using System;
using System.Collections.Generic;
using System.Text;
using System.ServiceModel;

namespace DerivativesCalculatorService
{
    [ServiceContract]
    public interface IDerivativesCalculator
    {
        [OperationContract]

            string[] symbols,
            decimal[] parameters,
            string[] functions);

        void DoNothing();
    }
}


using System;
using System.Collections.Generic;

namespace DerivativesCalculator

    public class Program

        public static void Main(string[] args)

            string httpBaseAddress = ConfigurationManager.AppSettings["HTTPBaseAddress"];
            string tcpBaseAddress = ConfigurationManager.AppSettings["TCPBaseAddress"];

            Uri httpBaseAddressUri = new Uri(httpBaseAddress);
            Uri tcpBaseAddressUri = new Uri(tcpBaseAddress);
            Uri[] baseAdresses = new Uri[] {
                httpBaseAddressUri,
                tcpBaseAddressUri};

            using (ServiceHost host = new ServiceHost(
                serviceType,
                baseAdresses))
            {
                host.Open();

                Console.WriteLine("The derivatives calculator service is available.");
                Console.ReadKey();

                host.Close();
            }
        }
    }
}

How to solve this?

Answer 1

I believe that this line of your configuration file is incorrect:

<service
type="DerivativesCalculator.DerivativesCalculatorServiceType,DerivativesCalculatorService"
behaviorConfiguration="DerivativesCalculatorService">

I think instead the type="" should be name="".

<service
name="DerivativesCalculator.DerivativesCalculatorServiceType,DerivativesCalculatorService"
behaviorConfiguration="DerivativesCalculatorService">
