MessageCredentialType is an enum. You can set MessageCredentialType.Certificate and set certificate credentials. You should look at documentation of MessageCredentialType enum where you can find example of setting certificate credentials.
I used this example to verify that it works. whole program looked like
using System;
using System.ServiceModel;
namespace ConsoleApplication2
{
[ServiceContract(Namespace = "http://UE.ServiceModel.Samples")]
public interface ICalculator
{
[OperationContract(IsOneWay = false)]
double Add(double n1, double n2);
[OperationContract(IsOneWay = false)]
double Subtract(double n1, double n2);
[OperationContract(IsOneWay = false)]
double Multiply(double n1, double n2);
[OperationContract(IsOneWay = false)]
double Divide(double n1, double n2);
}
public class CalculatorService : ICalculator
{
public double Add(double n1, double n2)
{
double result = n1 + n2;
Console.WriteLine("Received Add({0},{1})", n1, n2);
Console.WriteLine("Return: {0}", result);
return result;
}
public double Subtract(double n1, double n2)
{
double result = n1 - n2;
Console.WriteLine("Received Subtract({0},{1})", n1, n2);
Console.WriteLine("Return: {0}", result);
return result;
}
public double Multiply(double n1, double n2)
{
double result = n1 * n2;
Console.WriteLine("Received Multiply({0},{1})", n1, n2);
Console.WriteLine("Return: {0}", result);
return result;
}
public double Divide(double n1, double n2)
{
double result = n1 / n2;
Console.WriteLine("Received Divide({0},{1})", n1, n2);
Console.WriteLine("Return: {0}", result);
return result;
}
}
public class Client : ClientBase<ICalculator>, ICalculator
{
public double Add(double n1, double n2)
{
return base.Channel.Add(n1, n2);
}
public double Subtract(double n1, double n2)
{
throw new NotImplementedException();
}
public double Multiply(double n1, double n2)
{
throw new NotImplementedException();
}
public double Divide(double n1, double n2)
{
throw new NotImplementedException();
}
}
internal class Program
{
private static void Main(string[] args)
{
ServiceHost myServiceHost = new ServiceHost(typeof(CalculatorService));
// Open the ServiceHostBase to create listeners and start listening for messages.
myServiceHost.Open();
// The service can now be accessed.
Console.WriteLine("The service is ready.");
Console.WriteLine("Press <ENTER> to terminate service.");
Console.WriteLine();
Client c = new Client();
var res = c.Add(1, 2);
Console.ReadLine();
}
}
}
My configuration file looked like this
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.serviceModel>

It worked for me.
