未检测到Web服务?

我正在尝试托管此服务,但是当我在另一个Visual Studio运行时中打开一个新项目并试图添加一个无法找到任何内容的Web服务时,该服务运行良好?不在指定的地址或本地机器上的任何地方?以下代码似乎只在我在同一解决方案中运行时才有效?

namespace Students
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create the address for the service
            Uri address = new Uri("http://localhost:8001");
            // Create the binding for the service
            WSHttpBinding binding = new WSHttpBinding();
            // Create the service object
            StudentService service = new StudentService();
            // Create the host for the service
            ServiceHost host = new ServiceHost(service, address);
            // Add the endpoint for the service using the contract, binding and name
            host.AddServiceEndpoint(typeof(IStudentService),
                                    binding,
                                    "students");

            // Open the host
            host.Open();
            Console.WriteLine("Student service started");
            Console.WriteLine("Press return to exit");
            Console.ReadLine();
            // Close the host
            host.Close();
        }
    }


}

当我尝试从新项目中添加它(分离到当前解决方案)时得到的错误是:

The HTML document does not contain Web service discovery information.
Metadata contains a reference that cannot be resolved: 'http://localhost:8001/'.
There was no endpoint listening at http://localhost:8001/ that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
The remote server returned an error: (404) Not Found.
If the service is defined in the current solution, try building the solution and adding the service reference again.

当我下载此案例研究(初学者项目)时,它只是从控制台应用程序托管的任何地方都没有Web或应用程序配置文件。

另请注意,当我尝试添加Web服务时,我正在运行该服务。

在ServiceHost中添加元数据交换行为。

namespace Students
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create the address for the service
            Uri address = new Uri("http://localhost:8001");
            // Create the binding for the service
            WSHttpBinding binding = new WSHttpBinding();
            // Create the service object
            StudentService service = new StudentService();
            // Create the host for the service
            ServiceHost host = new ServiceHost(service, address);
            // Add the endpoint for the service using the contract, binding and name
            host.AddServiceEndpoint(typeof(IStudentService),
                                    binding,
                                    "students");

            // Add metadata exchange
            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = true;
            host.Description.Behaviors.Add(smb);

            // Open the host
            host.Open();
            Console.WriteLine("Student service started");
            Console.WriteLine("Press return to exit");
            Console.ReadLine();
            // Close the host
            host.Close();
        }
    }
}

您需要使用有关服务的信息创建/更新app.config文件。 查看:http://msdn.microsoft.com/en-us/library/ms734765.aspx
