How can I configure a WSDL client created with Connected Services to use Basic Authentication?

I have a 3-rd party WSDL service that I need to integrate in a .NET Core 2.1 webapp.

I added the service via "Add Connected Service" > "Microsoft WCF Web Service Reference Provider".

I have some utility class that configures the service like this:

ServiceClient servicePort = new ServiceClient(); 

servicePort.ClientCredentials.UserName.UserName = USERNAME;
servicePort.ClientCredentials.UserName.Password = PASSWORD;

setupHttpHeader(servicePort.InnerChannel );

where 

    public static void setupHttpHeader( IClientChannel serviceChannel )
    {
        using (new OperationContextScope( serviceChannel ))
        {
            // Add a HTTP Header to an outgoing request
            HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();
            requestMessage.Headers["Authorization"] = "Basic " + System.Convert.ToBase64String(Encoding.UTF8.GetBytes(USERNAME + ":" + PASSWORD));
            OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;
        }
    }

Now, when I try to call the endpoint in my controller, I get this exception:

System.ServiceModel.Security.MessageSecurityException: The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'basic realm="appbox object-model"'.

In an old .NET Framework 4.0 Sample for connecting the the 3-rd party service there was an app.config that had some configurations for the bindings. They looked like this: 

      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" />
      </security>

What do I need to add to my project in order to make this work?

The solution was found in this issue comment.

In the GetBindingForEndpoint section of the generated code, there needs to be something like:

System.ServiceModel.BasicHttpBinding result = new System.ServiceModel.BasicHttpBinding(System.ServiceModel.BasicHttpSecurityMode.Transport);
result.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Basic;

In my case I needed TransportCredentialOnly as the the endpoint was http not https.
