【问题描述】：

我正在尝试遵循 Microsoft 的 WCF 教程，并且正在执行此步骤：http://msdn.microsoft.com/en-us/library/ms733133.aspx

不幸的是，当我运行这个命令时：

svcutil.exe /language:cs /out:generatedProxy.cs /config:app.config http://localhost:8000/ServiceModelSamples/service

它给了我一个 404 错误。该服务正在运行，我可以通过 Web 浏览器成功访问它：http://localhost:8000/ServiceModelSamples/service

我做错了什么？如果它有助于我在下面发布我正在使用的示例主机的所有代码。

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

namespace Microsoft.ServiceModel.Samples
{
    class Program
    {
        static void Main(string[] args)
        {
            Uri BaseAddress = new Uri("http://locoalhost:8000/ServiceModelSamples/Service");
            ServiceHost selfHost = new ServiceHost(typeof(CalculatorService), BaseAddress);

            try
            {
                selfHost.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "CalculatorService");
                ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
                smb.HttpGetEnabled = true;
                selfHost.Description.Behaviors.Add(smb);

                selfHost.Open();
                Console.WriteLine("The service is ready.");
                Console.WriteLine("Press <ENTER> to terminate service.");
                Console.WriteLine();
                Console.ReadLine();
                selfHost.Close();
            }
            catch (CommunicationException ce)
            {
                Console.WriteLine("An expection occurred: {0}", ce.Message);
                selfHost.Abort();
            }
        }

        [ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
        public interface ICalculator
        {
            [OperationContract]
            double Add(double n1, double n2);

            [OperationContract]
            double Subtract(double n1, double n2);

            [OperationContract]
            double Multiply(double n1, double n2);

            [OperationContract]
            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);
                // Code added to write output to the console window.
                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;
            }
        }
    }
}

【解决方案1】：

第一件事是你有一个错字localhost（你有本地主机）

Uri BaseAddress = new Uri("http://locoalhost:8000/ServiceModelSamples/Service");

您还可以下载 fiddler@http://fiddler2.com/fiddler2/ 以查看流量和客户端代码发出的请求。这将提供下一个线索。在对 http 服务进行故障排除时，它是必不可少的。

另外，请确保您的配置良好。见：http://msdn.microsoft.com/en-us/library/ms734663.aspx
