在MSDN步行通过一个错误 - "如何：使用在Windows服务主机WCF TCP" [英] An error in the MSDN walk-through - "How to: Host WCF in a Windows Service Using TCP"

问题描述

我一直在敲打我的头靠在一个砖墙的近2天尝试成功地使用MSDN上的这个例子：

的如何：主机WCF在Windows服务使用TCP

如果您按照例如，通过并放置在同一个解决方案中的消费者应用程序，然后运行成功！ - 即使服务被关闭

如果服务接通和消费者的应用程序发布到说一个不同的网络驱动器，那么它将无法运行，因为WCF是不听。

下面这段在步行通过代码是罪魁祸首：

 保护覆盖无效的OnStart（字串[] args）
 {
如果（myServiceHost！= NULL）
 {
 myServiceHost.Close（）; 
} 
 myServiceHost =新的ServiceHost（typeof运算（服务1））; 
 myServiceHost.Open（）; 
} 
  

我的朋友注意到，如果我们改变新的ServiceHost（ typeof运算（服务1））; 到新的ServiceHost（typeof运算（WcfServiceLibrary1.Service1））; 则WCF将真正开始听

容易看到它的混乱，因为有一个Windows服务项目藏汉为WCF项目，以便在需要完整的资质中调用Service1类。

有没有其他人碰到这个？

解决方案

我有同样的问题（如你知道<一个HREF =http://stackoverflow.com/questions/12750413/consuming-a-wcf-service-that-is-hosted-in-a-windows-service-from-outside-solutio/12800645#12800645>原帖在计算器）。

另外，你可以重命名的命名空间WcfServiceLibrary1以避免冲突的类服务。

I've been banging my head against a brick-wall the past 2 days trying to successfully use this example on MSDN:

How to: Host WCF in a Windows Service Using TCP

If you follow the example through and place the Consumer application within the same solution then it runs successfully - even if the service is turned off !

If the service is switched on and the consumer application is published to say a different network drive then it will not run because the WCF is not listening.

The following piece of code in the walk-through is the culprit:

protected override void OnStart(string[] args)
{
   if (myServiceHost != null)
   {
       myServiceHost.Close();
   }
   myServiceHost = new ServiceHost(typeof(Service1));
   myServiceHost.Open();
}

My friend noticed that if we change new ServiceHost(typeof(Service1)); to new ServiceHost(typeof(WcfServiceLibrary1.Service1)); then the WCF will actually start to listen!

Easy to see it's confusion as there is a class called Service1 within the windows service project aswell as the WCF project so the full qualification is required.

Did anyone else encounter this?

解决方案

I had the same issue (as you know from the original post in stackoverflow).

Alternatively, you can rename the class Service1 in the namespace WcfServiceLibrary1 to avoid conflicts.
