C＃WCF - 调用服务失败

尝试使用WCF测试客户端命中我的新Web服务时出现以下错误。奇怪的是每隔一段时间它会执行一次然后开始弹出这个错误。C＃WCF - 调用服务失败

无法调用该服务。可能的原因：服务处于脱机状态或无法访问;客户端配置与代理不匹配;现有的代理无效。有关更多详细信息，请参阅堆栈跟踪。您可以尝试通过启动新代理，还原为默认配置或刷新服务来进行恢复。

我的代码（接口）：

[ServiceContract(Namespace = "http://rivworks.com/Services/2010/04/19")] 
public interface ISync 
{ 
    [OperationContract] 
    bool Execute(long ClientID); 
}

我的代码（类）：

public class Sync : ISync 
{ 
    #region ISync Members 
    bool ISync.Execute(long ClientID) 
    { 
     return model.Product(ClientID); 
    } 
    #endregion 
}

我的配置（编辑 - 发布整个serviceModel部分）：

2个问题：

我错过了什么导致这个错误？
如何增加服务的时间？

TIA！

TIA是什么意思？ – Peter 2010-04-19 21:45:13

@Petoj：意思是“提前致谢” – 2010-04-19 21:49:12

你可以重新发布你的配置文件吗？在下有两个关闭标签，但只有一个开头标签。我无法分辨您是否仅仅删减了相关服务，或者确实搞砸了。 – 2010-04-19 21:55:59

发现问题（S）...

有不是处理Web服务中的错误。
测试应用程序在发现错误时不会执行ABORT。相反，它没有处理（并且未报告）AND由于错误，通道现在被锁定。

把一个try/catch绕进去方法使得它，所以我可以记录错误和测试程序不锁定。
