我正在编写Windows服务中托管的netTcpRelayBinding WCF服务。由于缺乏Windows服务开发经验，我觉得我的代码很幼稚。这从Windows-Azure中调用。您能否帮我查看一下代码，以及我如何即兴创作： - 我们使用NLOG进行日志记录。netTcpRelayBinding Windows服务中托管的WCF服务 - 标准实践
我的服务抛出异常（问题结束时提到）。
应该如何： - 1.定义Windows服务依赖关系（它应该在机器获得 连接到互联网之前开始）。 2.它应该如何更容错，如何在一定的时间间隔后启动。

这有时会抛出以下异常（我想这是缺乏Windows服务的依赖，我想这项服务，启动时启动后，机器可以连接到互联网& SQL Server服务）。
