我正在尝试使用已配置的端点在 IIS（IIS7、Windows 7）上设置 WCF 服务，并且与 IIS 配置一样，这是一个充满伤害的世界。该服务在 VS2010 的调试器下工作正常，但是当我开始部署它时，我在打开时收到以下消息http://localhost:9000/MyApplication/_vti_bin/ListData.svc：

[UriFormatException: Invalid URI: The hostname could not be parsed.]
  System.Runtime.AsyncResult.End(IAsyncResult result) +650220
  System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result) +210733
  System.Web.AsyncEventExecutionStep.OnAsyncEventCompletion(IAsyncResult ar) +166

有趣的是，如果我刷新它，消息会发生变化：

[ArgumentException: An item with the same key has already been added.]
   System.Runtime.AsyncResult.End(IAsyncResult result) +650220
   System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result) +210733
   System.Web.AsyncEventExecutionStep.OnAsyncEventCompletion(IAsyncResult ar) +166

我认为第二个错误是第一个错误的结果，所以我试图先找到它。

现在，我知道您在想什么：“在这个关头看到一个又长又无聊的 Web.Config 文件真是太好了。” 你的愿望就是我的命令：

<?xml version="1.0"?>

    <add key="loggingenabled" value="true" />

        </endpoint>

    </bindings>
  </system.serviceModel>

  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

显然，我已经努力混淆确切的机器、应用程序和端口名称，所以如果那里有轻微的不匹配，可能不是问题。

在 IIS 上，我已将站点上的绑定配置为包含 net.msmq - 我对该问题的最佳猜测是“绑定信息”不正确 - 如果我将其设置为当前机器的机器名称，我会收到上述消息，如果我将它设置为“localhost”，它给了我一个 ASP.Net 服务器错误，事件日志和 WCF 跟踪文件中出现以下内容：

The service '/MyApplication/_vti_bin/ListData.svc' does not exist. ---> System.ServiceModel.EndpointNotFoundException: The service '/MyApplication/_vti_bin/ListData.svc' does not exist.

我猜它抱怨的 URI 可能是绑定信息中的主机名，但我找不到任何关于它需要什么的信息，或者如果localhost正确，如何深入研究问题。

编辑添加：启用 WCF 跟踪后，我看到发生以下模式：

<Description>MsmqActivation service started scan for queues.</Description>
<AppDomain>/LM/W3SVC/2/ROOT/MyApplication-1-130053972428149879</AppDomain>

然后

<Description>Throwing an exception.</Description><AppDomain>/LM/W3SVC/2/ROOT/My-Application-1-130053972428149879</AppDomain>
<Exception>
  <ExceptionType>System.ServiceModel.EndpointNotFoundException, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType>

</StackTrace><ExceptionString>System.ServiceModel.EndpointNotFoundException: The service '/MyApplication/_vti_bin/ListData.svc' does not exist.</ExceptionString>
</Exception>

最后我们看到这个：

<Description>MsmqActivation service cannot discover queues.</Description>
<AppDomain>/LM/W3SVC/2/ROOT/MyApplication-1-130053250352242318</AppDomain>

<Exception>

     at System.ServiceModel.Channels.MsmqBindingMonitor.OnTimer(Object state)
  </ExceptionString>
</Exception>

现在这个最后的异常看起来可能是最具指示性的——当我试图写入的队列是时，系统似乎正在寻找一个公共./private$/MyApplication队列——那么我需要改变什么以将其指向正确的方向？

我有同样的问题，并在这里找到了解决方案 - http://vijayvepak.blogspot.ru/2012/09/an-item-with-same-key-has-already-been.html 解决方案：转到 IIS，转到webapp的网站。右键单击 -> 编辑绑定 确保 net.msmq 协议的绑定信息设置为 localhost

它对我们有这个错误的所有工作站都有帮助。

IIS 只支持 Http 协议。如果您需要使用 MSMQ，您必须选择其他选项，例如 WAS 或自托管（win forms、WPF 或 Win 服务）。在下表中，您可以找到每个 WCF 托管选项支持的功能。
