ServiceHost仅支持类服务类型

Question

我正在创建一个WCF服务，它似乎昨天在VS测试客户端上运行良好，但今天它似乎在我尝试更改web.config文件后引发此错误。

下面

是代码和配置文件：

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

namespace TSService 
{ 
    interface name "IService1" in both code and config file together. 
    [ServiceContract] 
    public interface ITSService 

    [OperationContract] 
    List<Sel_Test> RunScript(List<SName> SNamesToRun, int LogPathIndex, RunEnvironment EnvironmentName, BOptions BType, NavOption NavEnum); 

} 

[DataContract] 
    public class STest 
    { 
     [DataMember] 
     public ScriptName SName { get; set; } 
     [DataMember] 
     public BOptions BTypeUsed { get; set; } 
     [DataMember] 
     public int SResult { get; set; } 
    } 

    [DataContract(Name= "SName")] 
    public enum SName 
    { 
     [EnumMember] 
     PXXXX1, 
     [EnumMember] 
     PXXXX2, 
     [EnumMember] 
     PXXXX3, 
     [EnumMember] 
     PXXXX4 

    } 

    [DataContract] 
    public enum NavOption 
    { 
     [EnumMember] 
     ContinueToNext, 
     [EnumMember] 
     Skip, 
     [EnumMember] 
     SignIn, 
     [EnumMember] 
     Registration 
    } 

    [DataContract] 
    public enum BOptions 
    { 
     [EnumMember] 
     FAA1, 
     [EnumMember] 
     ReFi, 
     [EnumMember] 
     RIE 
    } 

    [DataContract] 
    public enum RunEnvironment 
    { 
     [EnumMember] 
     D, 
     [EnumMember] 
     Q, 
     [EnumMember] 
     S, 
     [EnumMember] 
     P 
    } 
    [DataContract] 
    public enum PType 
    { 
     [EnumMember] 
     MAPD, 
     [EnumMember] 
     PDP, 
     [EnumMember] 
     MA, 
     [EnumMember] 
     Mgap 
    }; 
} 

在配置文件中我有：

<system.serviceModel> 

    <behaviors> 
     <serviceBehaviors> 
     <behavior name="TSServiceBehavior"> 
      <!-- To avoid disclosing metadata information, set the values below to false before deployment --> 
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/> 
      <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> 
      <serviceDebug includeExceptionDetailInFaults="true"/> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 

    <services> 
     <service name="TSService.ITSService" behaviorConfiguration="TSServiceBehavior"> 
     <endpoint address="" 
        binding ="basicHttpBinding" 
        contract="TSService.ITSService" /> 

     <endpoint address="mex" 
        binding="mexHttpsBinding" 
        contract="IMetadataExchange" /> 
     </service> 
    </services> 


    <bindings> 
     <basicHttpBinding> 
     <binding name ="TSServiceBinding" receiveTimeout="00:20:00" sendTimeout="00:20:00"> 
      <security mode="None"/> 
     </binding> 
     </basicHttpBinding> 
    </bindings> 


    <!--<protocolMapping> 
     <add binding="basicHttpsBinding" scheme="https" /> 
    </protocolMapping>--> 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="False" multipleSiteBindingsEnabled="true"/> 
    </system.serviceModel> 
    <system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"/> 
    <!-- 
     To browse web app root directory during debugging, set the value below to true. 
     Set to false before deployment to avoid disclosing web app folder information. 
     --> 
    <directoryBrowse enabled="true"/> 
    </system.webServer> 



    <system.diagnostics> 
    <sources> 
     <source name="System.ServiceModel" 
       switchValue="Information, ActivityTracing" 
       propagateActivity="true"> 
     <listeners> 
      <add name="traceListener" 
       type="System.Diagnostics.XmlWriterTraceListener" 
       initializeData= "c:\log\Traces.svclog" /> 
     </listeners> 
     </source> 
    </sources> 
    </system.diagnostics> 

在SVC标记

我有：

<%@ ServiceHost Language="C#" Debug="true" Service="TSService.ITSService" CodeBehind="TSService.svc.cs" %> 

的错误，我在运行VS WCFTest客户端时得到：
