ssis 找不到端点元素

Question

I am creating SSIS package and coding in SSIS Script Task. In my code I am connecting to thirdparty service and not able to connect due to the error below

So I checked my app.config file and saw the blue squigly line, I dont why it is there. Here is my app.config file

The I deleted the contract and start typing, I found that the service is not listed in the contract attribute.

Here is my code file

        namespace ST_5fbd7f2f2bb84852b98e39162197f9df
     {
    using System;
     using System.Collections.Generic;
     using System.Linq;
     using System.ServiceModel;
     using System.ServiceModel.Channels;
     using System.Text;
     using LoginServiceReference;
 [Microsoft.SqlServer.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute]
     public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
     {
 public void Main()
         {
             // TODO: Add your code here
         LoginServiceClient loginClient = null;
             try
             {
                 // Setup your user credentials.
                 string Message = "";
                 string AuthenticationToken = "";
                 string UserName = "";
                 string Password = "";
                 string UserAPIkey = "";
                 string CustomerAPIkey = "";
                 int TotalPages = 0;
                 // Create a proxy to the login service.
                 loginClient = new LoginServiceClient("WSHttpBinding_ILoginService");
    
                 // Submit the login request to authenticate the user.
                 AuthenticationStatus loginRequest = loginClient.Authenticate
                     (CustomerAPIkey, Password, UserAPIkey, UserName, out Message, out AuthenticationToken);
    
                 if (loginRequest == AuthenticationStatus.Ok)
                 {
                     MessageBox.Show("User authentication successful.");
                 }
                 else
                 {
                 MessageBox.Show("User authentication failed: " + Message.ToString());
                 }
                 Dts.TaskResult = (int)ScriptResults.Success;
             }
             catch (Exception ex)
             {
                 MessageBox.Show("Exception: " + ex.ToString());
                 Dts.TaskResult = (int)ScriptResults.Failure;
             }            }    }
    }

I would appreciate if you can help in this.

Here is what I have done.

I tried deleting .SUO (Solution Users Option) file after closing VS, so it can reset cashe for XMLEditor but it did not work.

Here is my version:

Microsoft Visual Studio Professional 2015 Version 14.0.25431.01 Update 3

Microsoft .NET Framework Version 4.7.02556

The configuration file that .NET looks for when it loads configuration data is the one for the executable that's actually running. SSIS will not use that app.config. See: SSIS With Script Component and Service References gives a little bit more details.

We use Ultipro's reports as a service and ran into the same issue. So in code you have to create the bindings and endpoints and ignore the app.config.

Add:

using System.ServiceModel;

Update your code, create a binding and endpoint and pass those to LoginServiceClient:

        var binding = new WSHttpBinding();
        binding.Security.Mode = SecurityMode.Transport;
        binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

        EndpointAddress loginEndPoint = new EndpointAddress("https://service5.ultipro.com/services/LoginService");

        loginClient = new LoginServiceClient(binding,loginEndPoint);

We store the endpoint address in project configurations and pass that into the script along with the credentials.
