我目前正在为 Windows Azure 开发 .net 应用程序。我已按照一些教程为要在 Azure 上托管的本地服务设置中继。这似乎奏效了。

但是，当我使用客户端对其进行测试时，我无法下载元数据。我收到以下错误：

无法识别 URI 前缀。找不到配置绑定扩展“system.serviceModel/bindings/netTcpRelayBinding”。验证此绑定扩展是否已在 system.serviceModel/extensions/bindingExtensions 中正确注册并且拼写正确。如果在当前解决方案中定义了服务，请尝试构建解决方案并再次添加服务引用。

似乎旧版本的 appfabric sdk 将扩展写入 machine.config，但新版本没有，您必须将其添加到您的 app.config。或者您可以使用 nugget 安装 windowsazure.servicebus 包，它会为您编写扩展。我已经这样做了，所以 app.config 确实包含 system.serviceModel/extensions/bindingExtensions/netTcpRelayBinding

这是我的 app.config

我已经把头撞在墙上有一段时间了，试图找出可能出了什么问题。美好的一天半，除了谷歌搜索之外什么都没有。我尝试过编辑 machine.config，但我尝试了很多不同的东西。到目前为止，没有任何工作。知道问题可能是什么吗？

确保在定义NetTcpRelayBinding 类的项目中引用Microsoft.ServiceBus程序集。

您需要添加一个名为 MYnetTcpRelayBinding 的绑定：

<bindings>
  <netTcpRelayBinding>
    <binding name="netTcpRelayBinding" ....

并更改您的端点以使用该绑定：

<client>
      <endpoint address="" binding="MYnetTcpRelayBinding" ...
