WCF-双工连接（在IIS中托管）

Question

我有一个全双工，我在我的本地机器上成功运行。 我在我的服务器（IIS - server 2008 R2-STANDARD）中托管它，并尝试连接，如下所示：

this.myCallbackProxy = new MyCallbackProxy();
  InstanceContext cntx = new InstanceContext(myCallbackProxy);
  this.Proxy = new MyServiceClientProxy(cntx, "WSDualHttpBinding_I_BridgeWCFService");
  this.Proxy.ClientCredentials.Windows.ClientCredential.UserName = "YY";
  this.Proxy.ClientCredentials.Windows.ClientCredential.Password = "PP";

现在，当我尝试调用API时，我一直坚持到时间。

我尝试在IIS中配置WCF以作为特定用户进行连接，但是当我尝试从客户端调用API时，我得到以下异常：

"The content type text/html; charset=utf-8 of the response message does not match the content type of the binding (application/soap+xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 1024 bytes of the response"

我必须提一下，我在同一个IIS中托管了另一个WCF，具有相同的用户（服务器用户名），并且它工作得很完美。 （我为双工WCF创建了另一个（类似的）应用程序轮询）

我的配置文件：
