C# WCF -未能调用服务

Question

当我试图使用WCF测试客户端访问我的新web服务时，我得到了以下错误。奇怪的是，它每隔一段时间就会执行一次，然后开始弹出这个错误。

未能调用该服务。可能的原因:服务脱机或不可访问；客户端配置与代理不匹配；现有代理无效。有关更多细节，请参阅堆栈跟踪。您可以尝试通过启动新代理、恢复到默认配置或刷新服务来恢复。

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
}

2个问题：

1. 我遗漏了什么导致此错误？
2. 如何增加服务的超时时间？

Answer 1

发现了问题..。

1. 在未处理的web服务中出错。测试应用程序
2. 在看到错误时不会执行中止操作。相反，它未被处理(和未报告)和--由于错误，通道现在被锁定。

在inside方法周围放置一个try/catch，这样我就可以记录错误和，测试应用程序不会锁定。
