Question

我正在尝试为我的WCF应用程序创建服务主机。当我启动应用程序时，我收到错误说

无法启动该服务。此服务没有定义端点。请在配置文件中添加至少一个服务端点再试一次。

我遵循了PluralSight上的教程，这是我提出的代码

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;
        }
    }

的app.config

<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

Answer 1

tl; dr; 修复App.config

中的名称

对我来说，这个问题是由ReSharper引发的：我重命名了这个服务，并没有在任何地方重命名它。

进入App.config更正服务和界面名称以解决问题。

Answer 2

我遇到了同样的问题。

我的问题是缺少合同属性

[ServiceContract] //System.ServiceModel.ServiceContract
public interface IPdaContract
{

无法启动wcf服务主机
