c# - 无法启动 wcf 服务主机

Question

我正在尝试为我的 WCF 应用程序创建一个服务主机。当我启动应用程序时，我收到一条错误消息

The service cannot be started. This service has no endpoint defined. Please add at least one endpoint for the service in config file and try again.

我遵循了 PluralSight 上的教程，这是我想出的代码

using System.ServiceModel;
using FreedomService;

namespace ConsoleHost
{
    class Program
    {
        static void Main(string[] args)
        {
            var host = new ServiceHost(typeof(PeopleService));
            host.AddServiceEndpoint(typeof (IPeopleService), new BasicHttpBinding(),
                                    "http://localhost:8080/people/basic");
            host.AddServiceEndpoint(typeof(IPeopleService), new WSHttpBinding(), 
                                    "http://localhost:8080/people/ws");
            host.AddServiceEndpoint(typeof(IPeopleService), new NetTcpBinding(), 
                                    "net.tcp://localhost:8081/people");
            try
            {
                host.Open();
                PrintServiceInfo(host);
                Console.ReadLine();
                host.Close();
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                host.Abort();
            }
        }

        static void PrintServiceInfo(ServiceHost host)
        {
            Console.WriteLine("{0} is up and running with these endpoints:",host.Description.ServiceType);
            foreach (var endpoint in host.Description.Endpoints)
            {
                Console.WriteLine(endpoint.Address);
            }
        }

    }
}

IPeopleService.cs

[ServiceContract]
public interface IPeopleService
{
    [OperationContract]
    string GetData(int value);

    [OperationContract]
    PersonType GetPersonById(int id);
}

PeopleService.cs

public class PeopleService : IPeopleService, IDisposable
    {
        private ICollection<PersonType> People = new Collection<PersonType>
            {
                //...
            };
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }

        public PersonType GetPersonById(int id)
        {
            var person = People.First(p => p.Id == id);
            if (person!= null)
                return person;
            throw new InvalidDataException(string.Format("No Person with the id: {0} found.",id));
        }

        public void Dispose()
        {
            this.People = null;
        }
    }

应用程序配置

Answer 1

tl;dr; 修复 App.config

中的名称

对我来说，这个问题是由 ReSharper 触发的:我重命名了服务，但它并没有在所有地方重命名。

进入 App.config 更正服务和接口(interface)名称以解决问题。
