我发现一个错误,我无法为服务提取元数据。当我看WCFExtras样本时,它看起来都很好,样本也很好。唯一的区别是,我的WCF服务是.NET 4.0。

这就是我的网络。

This is what my interface looks like:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using WCFExtras.Wsdl.Documentation;

namespace CDITecServices
{
    [XmlComments]
    [ServiceContract]
    public interface ITECServiceHelper
    {

        [OperationContract]
        void DownloadDataFile(string OrderTicketId, string Username,
                              string Password, string UserDatabase);

        [OperationContract]
        List<string> GetRecordsFromFile(string OrderTicketId, ref long StartIndex);

        // TODO: Add your service operations here
    }
}
