出于某种原因,我无法将 Visual Studio 2010 调试器附加到使用 WCF 服务库的服务中,我从这里开始遵循 MSDN 教程。当我安装并运行该服务时,它工作得很好,并且我可以从客户端 GUI 访问所有内容,但是当我尝试将调试器附加到服务时,我得到以下 WCF 服务主机窗口,该窗口弹出一个错误:

System.ServiceModel.AddressAlreadyInUseException: There is already a listener on IP endpoint 0.0.0.0:8000.  Make sure that you are not trying to use this endpoint multiple times in your application and that there are no other applications listening on this endpoint. ---> System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted

   at System.Net.Sockets.Socket.Bind(EndPoint localEP)
   at System.ServiceModel.Channels.SocketConnectionListener.Listen()

该问题发生在OnStart()服务函数中的 myServiceHost.open() 上,如下所示:

public partial class ORAS : ServiceBase
    {
        System.Timers.Timer aTimer;
        OWcfServiceLibrary.OService ORAS = new OService();
        internal static ServiceHost myServiceHost = null; 
        public ORAS()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            System.Diagnostics.Debugger.Launch();
            aTimer = new System.Timers.Timer(60000);//every minute
            aTimer.AutoReset = true;
            aTimer.Elapsed += new System.Timers.ElapsedEventHandler(aTimer_Has_Alarm);
            aTimer.Enabled = true;
            if (myServiceHost != null)
            {
                myServiceHost.Close();
            }
            myServiceHost = new ServiceHost(typeof(OrionService));
            myServiceHost.Open();
        }

在我看来,您有两次尝试类似serviceHost.AddServiceEndpoint(),其中第一次是服务本身,然后在您开始调试时再次尝试。

如果您满足以下条件,您可以进入服务代码:

  1. “以管理员身份”运行 Visual Studio。
  2. 让服务运行并准备就绪。
  3. 在调试中启动您的客户端代码,并在调用服务的行上放置一个断点。

当您的客户端代码遇到断点时,使用Step Into (F11)移动到服务代码。如果设置正确,它将无缝转换为服务代码,您可以在其中继续执行。

替代:

  1. 停止您的服务。
  2. 在您的服务OnStart()方法中,首先放置以下行: System.Diagnostics.Debugger.Launch();
  3. 重建然后启动服务
  4. 当新的代码行被点击时,系统会提示您选择调试器...选择已经打开的项目

那应该会让你进入新的launch()行列。
