Ce App.config génère l'exception suivante:

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

Mon code source est comme suit:

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

     void DoNothing(); 
    } 
} 


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

namespace DerivativesCalculator 
{ 
    public class Program 
    { 
     public static void Main(string[] args) 
     { 
      Type serviceType = typeof(DerivativesCalculatorServiceType); 

      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(); 
      } 
     } 
    } 
} 

Comment résoudre ce problème?

Je crois que cette ligne de votre fichier de configuration est incorrect:

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

Je pense plutôt que le type = "" doit être name = "".

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