一般有两种方式实现：

1、通过代码设置直接实现

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.Text;
using WcfTest;

namespace WcfHosting
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            using (ServiceHost host = new ServiceHost(typeof (SoapService)))
            {
                host.AddServiceEndpoint(typeof(ISoapService), new WSHttpBinding(), "http://127.0.0.1:1234/neohope");

                if (host.Description.Behaviors.Find<ServiceMetadataBehavior>() == null)
                {
                    ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
                    behavior.HttpGetEnabled = true;
                    behavior.HttpGetUrl = new Uri("http://127.0.0.1:9999/neohope/metadata");
                    host.Description.Behaviors.Add(behavior);
                }

                host.Opened += delegate
                {
                    Console.WriteLine("service started, press enter to exit.");
                };
                host.Open();
                Console.Read();
            }
        }
    }
}

2、通过配置文件实现

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.Text;
using WcfTest;

namespace WcfHosting
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            using (ServiceHost host = new ServiceHost(typeof (SoapService)))
            {
                host.Opened += delegate
                {
                    Console.WriteLine("service started, press enter to exit.");
                };
                host.Open();
                Console.Read();
            }
        }
    }
}

app.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="metadataBehavior">
          <serviceMetadata httpGetEnabled="true" httpGetUrl="http://127.0.0.1:9999/neohope/metadata" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="metadataBehavior" name="WcfTest.SoapService">
        <endpoint address="http://127.0.0.9999/neohope" binding="wsHttpBinding"
                  contract="WcfTest.ISoapService" />
      </service>
    </services>
  </system.serviceModel>
</configuration>

有三个地方可以修改SOAP的命名空间：

1、ServiceContract

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using System.Web.Configuration;

namespace WcfTest
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract(Name="SoapService",Namespace="http://wcftest.neohope.org")]
    public interface ISoapService
    {
        [OperationContract]
        [WebInvoke(Method = "GET", UriTemplate = "User/Get/{uid}", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
        NUser GetUser(String uid);

        [OperationContract]
        [WebInvoke(Method = "POST", UriTemplate = "/User", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
        string UpdateUser(NUser newuser);


        [OperationContract]
        [WebInvoke(Method = "PUT", UriTemplate = "/User", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
        string AddUser(NUser newuser);


        [OperationContract]
        [WebInvoke(Method = "DELETE", UriTemplate = "/User", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
        string DeleteUser(String uid);
    }

    [ServiceBehavior(Name = "SoapService", Namespace = "http://wcftest.neohope.org")]
    [DataContract]
    public class NUser
    {
        string uid = "";
        string uname = "";
        string usex = "";

        [DataMember]
        public String Uid
        {
            get { return uid; }
            set { uid = value; }
        }

        [DataMember]
        public string UName
        {
            get { return uname; }
            set { uname = value; }
        }

        [DataMember]
        public string USex
        {
            get { return usex; }
            set { usex = value; }
        }
    }
}

2、服务实现

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfTest
{
    [ServiceBehavior(Name = "SoapService", Namespace = "http://wcftest.neohope.org")]
   public class SoapService : ISoapService
    {
        static List<NUser> users = new List<NUser>();

        static SoapService()
        {
            NUser aNUser = new NUser();
            aNUser.Uid = "001";
            aNUser.UName = "张三";
            aNUser.USex = "男";
            users.Add(aNUser);
        }

        public NUser GetUser(string uid)
        {
            foreach (NUser nuser in users)
            {
                if (nuser.Uid == uid)
                {
                    return nuser;
                }
            }

            return null;
        }

        public string UpdateUser(NUser newuser)
        {
            if (newuser == null)
            {
                return "nuewuser is null";
            }

            foreach (NUser nuser in users)
            {
                if (nuser.Uid == newuser.Uid)
                {
                    nuser.UName = newuser.UName;
                    newuser.USex = nuser.USex;
                    return "User updated";
                }
            }

            return "User not found";
        }

        public string AddUser(NUser newuser)
        {
            if (newuser == null)
            {
                return "nuewuser is null";
            }

            foreach (NUser nuser in users)
            {
                if (nuser.Uid == newuser.Uid)
                {
                    nuser.UName = newuser.UName;
                    newuser.USex = nuser.USex;
                    return "User updated";
                }
            }

            users.Add(newuser);

            return "User added";
        }

        public string DeleteUser(String uid)
        {
            bool bFound = false;
            for(int i=users.Count-1;i>=0;i--)
            {
                if (users[i].Uid == uid)
                {
                    bFound = true;
                    users.RemoveAt(i);
                }
            }

            if (!bFound)
            {
                return "User Not Found";
            }
            else
            {
                return "User Deleted";
            }
        }
    }
}

3、Web.config

<?xml version="1.0"?>
<configuration>
  
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  
  <system.serviceModel>

    <services>
      <service name="WcfTest.SoapService">
        <endpoint binding="webHttpBinding" contract="WcfTest.ISoapService" bindingNamespace="http://wcftest.neohope.org"/>
      </service>
    </services>
 
    <behaviors>
      <endpointBehaviors>
      </endpointBehaviors>
      
      <serviceBehaviors>
        <behavior name="">

          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
