WCF使用Windows服务

Question

我正在创建一个WCF服务,该服务将托管在Windows服务中.我创建了一个控制台应用程序如下

我去管理控制台(services.msc)并启动了该服务.但是我得到了以下错误

本地计算机上的LijosWindowsService服务已启动,然后停止.如果没有工作要做,某些服务会自动停止,例如,性能日志和警报服务

我去了活动观众,得到了以下内容

服务无法启动.System.InvalidOperationException:服务'Lijo.Samples.WeatherService'具有零应用程序(非基础结构)端点.这可能是因为没有为您的应用程序找到配置文件,或者因为在配置文件中找不到与服务名称匹配的服务元素,或者因为在service元素中没有定义端点.

能告诉我这里缺少的链接吗？

您的配置和代码看起来很好 - 您确定在(您的应用程序).​​exe所在的同一目录中有一个(您的应用程序).​​exe.config文件,您启动的服务是什么？

错误消息将指示缺少配置文件.确保它在那里 - 否则您的NT服务无法根据需要设置WCF服务.
