两个端点共享相同的端点错误消息 [英] two endpoints share the same endpoint error message

问题描述

我有一个由IIS 6托管的WCF库，并且一切正常.但是，我需要逐步检查服务中的代码.但是，当我在VS2008中按F5时，出现以下错误消息. .

I have a WCF Library hosted by IIS 6 and it all works fine.  However I need to step through the code in the service.  But when I hit F5 in VS2008 I get the following error message. . .

一个绑定实例已经关联到侦听URI'http://localhost:8888/VtaxDataService'.如果两个端点要共享相同的ListenUri，则它们还必须共享相同的绑定对象实例.

A binding instance has already been associated to listen URI 'http://localhost:8888/VtaxDataService'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance.

我的机器上没有其他东西正在监听该URI.我以为该消息可能是指托管我的服务的网站，但是我在IIS中停止了该网站，但仍然收到该消息.我的app.config粘贴在下面.

nothing else on my machine is listening on that URI.  I thought the message might be referring to the website hosting my service but I stopped the web site in IIS and I still get the message.  My app.config is pasted below.

问题出在哪里，我该如何逐步看待这段代码?
感谢

What is the problem and how can I step through this code?
Thanks

推荐答案

您好，院长，

您的WCF服务已经托管在IIS 6中并且正在侦听在 http://localhost:8877/VtaxDataService 中.当您从Visual Studio运行服务时，它将在WcfSvcHost.exe中承载该服务，并尝试在上述端点上侦听，并且会收到错误消息.

要调试该服务，可以从IIS中删除服务，然后从WcfSvcHost.exe进行调试. .否则，请勿运行服务，添加断点并将进程附加到aspnet_wp.exe(ASP.NET辅助进程).

有关附加到正在运行的进程的更多信息，请参见:

Hi Dean,

Your WCF service is already hosted in IIS 6 and listening at http://localhost:8877/VtaxDataService. When you run service from Visual Studio it hosts the service in WcfSvcHost.exe and tries to listen at above endpoint and you receive error.

To debug the service you can remove your service from IIS and debug from WcfSvcHost.exe. Otherwise, do not run service, add breakpoint and attach process to aspnet_wp.exe (ASP.NET worker process).

For more information on attaching to running process see: http://msdn.microsoft.com/en-us/library/c6wf8e4z.aspx

Thanks,
