Question

为了概念验证，我正在尝试编写两个应用程序WcfApp1和WcfApp2。

问题： 我能够在WcfApp2解决方案中添加WcfApp1的服务引用，但无法在WcfApp1中添加WcfApp2。虽然代码相同（当然正在改变basic_httpbinding_url）。谁能告诉我这可能有什么问题？

详情：

WcfApp1有：

IWcfApp1_Class - ＆gt;接口;

WcfApp1_Class - ＆gt;从上面的接口派生的类;

WcfApp1_DClass - ＆gt; class（作为数据结构）;

WcfApp2有：

IWcfApp2_Class - ＆gt;接口;

WcfApp2_Class - ＆gt;从上面的接口派生的类;

WcfApp2_DClass - ＆gt; class（作为数据结构）;

WcfApp1代码：

Uri baseAddress_BasicHttpBinding = new Uri("http://localhost:9001/WcfApp1");
Uri baseAddress_NetTcpBinding = new Uri("net.tcp://localhost:9001/WcfApp1");
Uri baseAddress_NetNamedPipeBinding = new Uri("http://localhost:9001/WcfApp1");// new Uri("net.pipe://localhost:9001/WcfApp1");
Uri baseAddress_WSHttpBinding = new Uri("http://localhost:9001/WcfApp1");
Uri baseAddress_WSDualHttpBinding = new Uri("http://localhost:9001/WcfApp1");

ServiceHost host;

public void f_BasicHttpBinding()
{

    host = new ServiceHost(typeof(WcfApp1_Class), baseAddress_BasicHttpBinding);
    ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
    smb.HttpGetEnabled = true;
    smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;

    var behavior = host.Description.Behaviors.Find<ServiceBehaviorAttribute>();
    behavior.InstanceContextMode = InstanceContextMode.Single;

    host.Description.Behaviors.Add(smb);

    try
    {
        host.Open();
    }
    catch (Exception exxx)
    {
        Console.WriteLine(exxx.ToString());
    }
}

IWcfApp1_Class：
