Question

我需要从便携式库访问WCF服务，但我遇到了异常。

我使用c＃创建了一个NetHttpBinding：

        var serviceHost = new ServiceHost(classType, new Uri("http://localhost:23166/EbmsServices/DataAccess/E21/NET"));
        serviceHost.AddServiceEndpoint(endpointInterface, new NetHttpBinding(), "");

        var smb = new ServiceMetadataBehavior() { HttpGetEnabled = true };
        smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
        serviceHost.Description.Behaviors.Add(smb);
        serviceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpBinding(), "mex");

        // Open the ServiceHostBase to create listeners and start listening for messages.
        serviceHost.Open();

在客户端可移植库中，我使用Visual Studio添加了服务引用。

以下是便携式库中的代码：

        Service = new DataAccessClient(new NetHttpBinding() { SendTimeout = SendTimeout, ReceiveTimeout = ReceiveTimeout }, new EndpointAddress(ServiceUrl));
        Service.ValidateLoginCompleted += Service_ValidateLoginCompleted;
        Service.ValidateLoginAsync(new ValidateLoginRequest(Guid.NewGuid(), username, password));

服务启动很好，我可以从非可移植的库中访问它，但是当我尝试使用可移植库时，我得到了这个例外：

        An exception of type 'System.ServiceModel.EndpointNotFoundException' occurred in System.ServiceModel.Internals.dll but was not handled in user code

        Additional information: There was no endpoint listening at http://localhost:23166/EbmsServices/DataAccess/E21/NET that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

内部例外：无法连接到远程服务器

内在的例外：无法建立连接，因为目标计算机主动拒绝它[:: 1]：23166

在便携式库中，我需要做些什么才能使其工作？

为了记录，可移植库的目标是.Net Framework 4.5.1和Windows 8.1。此外，这在Windows 8.1应用程序中也可以使用。

谢谢！
