WCF返回错误“ net.pipe上没有端点在监听……”

Question

由于某种原因，我无法使服务的Net.Pipe端点（EP）正常工作。

这是IIS7中托管的.Net 4.0 WCF服务。

有两个错误...

• 首先，EP将不提供元数据。
• 其次，EP不能实际工作-我正在通过WCF测试客户端（它是VS2010的一部分）对其进行测试。

我认为两者实际上都与同一个问题有关。

收到的实际错误是...

There was no endpoint listening at net.pipe://[machinename].[domainname]/Services/TestService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

我注意到的第一件事是，无论我在基址中称呼我的管道如何，它都会被重命名为[machinename]。[domainname]，这似乎很奇怪。 这在输出的服务元数据中很明显。 但是，如果我在测试客户端中使用管道名称或此重命名的名称，则两者均将无效。

我还已经在Windows功能中启用WAS，设置了IIS中所有协议的站点绑定，并且还在IIS的“已启用协议”框中键入了协议名称（http，net.tcp，net.pipe）。 我还检查了Windows Servics中是否已启动“ Net.Pipe侦听器适配器”。

我的http和net.tcp EP都可以正常工作并返回元数据。

我的配置在下面列出-有没有人知道什么可以阻止此EP正常工作？ 我很确定这很简单！

Answer 1

在添加以下mex端点后，WCF测试客户端能够看到我的命名管道端点：

通过查看测试客户端生成的配置，我发现客户端的端点地址错误。 最终为我工作...

net.pipe://localhost/{webapproot}/{path}/ServiceName.svc/{relativeaddress}

我希望这可以帮助别人。
