c# - 実行中のサービスから WSDL ファイルを取得するにはどうすればよいですか?

Question

Web サービスを開始する方法は次のとおりです。

try
{
    //load the shedluer static constructor
    ServiceHost svh = new ServiceHost(typeof(OrderExecutor));

    var tcpbinding = new NetTcpBinding(SecurityMode.None);

    //remove limits on the max array size
    var httpLocation = "http://" + address + ":1234";

    svh.AddServiceEndpoint(typeof(IOrderExecutor), new WSHttpBinding(SecurityMode.None), httpLocation);

    ServiceMetadataBehavior smb = svh.Description.Behaviors.Find<ServiceMetadataBehavior>();

    if (smb == null)
        smb = new ServiceMetadataBehavior();

    smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
    svh.Description.Behaviors.Add(smb);

    // Add MEX endpoint

    svh.AddServiceEndpoint(
                ServiceMetadataBehavior.MexContractName,
                MetadataExchangeBindings.CreateMexHttpBinding(),
                httpLocation + "/mex"
                );


    svh.Open();
    Console.WriteLine("Service mounted at {0}", httpLocation);
    Console.WriteLine("Press Ctrl+c to exit");

    var re = new ManualResetEvent(false);
    re.WaitOne();
    svh.Close();
}
catch (Exception e)
{
    Console.WriteLine("Exception");
    Console.WriteLine(e);
} 

サービスが開始され、正常に動作します。Visual Studio はサービスに接続して、動作するクライアントを作成できます。

しかし、PHP と相互運用するには WSDL ファイルが必要です。

私はもう試した

http://localhost:1234?wsdl
http://localhost:1234/IOrderExecutor?wsdl
http://localhost:1234/IOrderExecutor.wsdl

成功せずに。

私も試してみました

svcutil /serviceName:IOrderExecutor order-executor.exe

次の結果で：

Warning: Unable to load a service with configName 'IOrderExecutor'. To export
 a service provide both the assembly containing the service type and an executab
le with configuration for this service.
    Details:Either none of the assemblies passed were executables with configura
tion files or none of the configuration files contained services with the config
 name 'IOrderExecutor'.

Warning: No metadata files were generated. No service contracts were exported.
 To export a service, use the /serviceName option. To export data contracts, spe
cify the /dataContractOnly option. This can sometimes occur in certain security
contexts, such as when the assembly is loaded over a UNC network file share. If
this is the case, try copying the assembly into a trusted environment and runnin
g it.
