Answer 1

I found a solution. You have to update WCF to the latest.

Go to NuGet Package Manager -> Update all related Project URL of WCF There must be:

System.ServiceModel.Security
System.ServiceModel.NetTcp
System.ServiceModel.Http

This apply to .net core 2.1 version.

You can try this

HttpWebRequest request = HttpWebRequest.Create("URI") as HttpWebRequest;
var proxy = new WebProxy(HttpWebRequest.GetSystemWebProxy().GetProxy(request.RequestUri), true);
proxy.Credentials = new NetworkCredential(proxyUserName, proxyPassword, DomainName);
request.Proxy = proxy;

hope it helps

In summary, this is how to set a proxy for a specific service in the web.config. In the binding config, set proxyAddress="http://myproxy:8080" and set useDefaultWebProxy="false"

<bindings>
  <basicHttpBinding>
     <binding name="SubscriberFulfilmentServiceSOAP12Binding" closeTimeout="00:01:00"
      openTimeout="00:01:00" receiveTimeout="00:01:00" sendTimeout="00:01:00"
      allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
      maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"
      textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="false"
proxyAddress="http://myproxy:8080"
      messageEncoding="Text">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
        maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None"
          realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
