通用应用程序中的WCF客户端

Question

是否可以从通用应用程序调用WCF服务？

我添加了一个服务引用,代理生成得很好.但是,当以编程方式创建NetTcpBinding并将其传递给代理的构造函数时,服务模型会抛出异常PlatformNotSupported.

在模拟器和本地计算机上运行应用程序都会生成相同的异常.

System.Private.ServiceModel.dll中发生了'System.PlatformNotSupportedException'类型的异常,但未在用户代码中处理

"不支持此操作"

EndpointAddress address = new EndpointAddress("net.tcp://test:9000/ServicesHost/PublishService");
NetTcpBinding binding = new NetTcpBinding();
binding.Security.Mode = SecurityMode.None;

PublishingService.PublishClient proxy = new PublishingService.PublishClient(binding, address);

有没有人在UAP中有一个工作的WCF客户端的例子？

编辑

它与服务是双工服务有关!

原合同:

[ServiceContract(CallbackContract = typeof(IPublishCallback))]
public interface IPublish { }

删除CallbackContract属性后,UAP客户端可以创建连接,因此基本WCF可以正常工作.所以我想最好改一下这个问题.是否可以在通用应用程序中创建双工 WCF客户端？

对的，这是可能的。这就是我在不久前完成的示例应用程序中连接的方式：

 using Tradeng.Srvc.Client.WinAppSimple.SrvcRefTradeng;

 private InstanceContext instanceContext;
 private TradengSrvcClientBase serviceProxy;

            instanceContext = new InstanceContext(this);
            serviceProxy = new TradengSrvcClientBase(instanceContext);

            bool result = await serviceProxy.ConnectAsync();

            if (result)
            {
              // connected...
            }

我使用了添加对服务的引用时生成的配置文件中的绑定。

这就是应用程序的样子。尖端的东西......：O）

顺便说一下，服务本身是作为WebRoleon运行的。Azure
