[HASSEN-MEDDEB-ATOS]

Hello,

i use .NET Core 3.1. I want to make specific api when i call Microsoft graph without using export http_proxy and https_proxy :

 public static class CRMConnection
    {

        private static CdsServiceClient sp = null;
        private static IWebProxy proxy = WebRequest.DefaultWebProxy;

        private static string Xml_Settings_PathWin = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.Parent.Parent.FullName + @"\VSMP_SECURE_SETTINGS.xml";
        private static string Xml_Settings_PathLin = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.Parent.Parent.Parent.FullName + @"/VSMP_SECURE_SETTINGS.xml";
        private static XmlDocument VSMP_Settings;


        public static CdsServiceClient InitCRMConnection()
        {
            try
            {
                EnableProxy();
                string connectionstring = ConfigurationManager.ConnectionStrings["connectionVSMPSecretkeyVSMP"].ConnectionString;
                sp = new CdsServiceClient(connectionstring);

                

            }

            catch (Exception ex)
            {
                      LogHelper.Writer("Erreur lors de la connexion au crm, Message de l'erreur : " + Environment.NewLine + ex.ToString());
            }

               return sp;
        }

        private static void EnableProxy()
        {
            VSMP_Settings = new XmlDocument();


            if (OperatingSysteme.IsLinux())
            {
                VSMP_Settings.Load(Xml_Settings_PathLin);
            }
            else
            {
                VSMP_Settings.Load(Xml_Settings_PathWin);

            }



            var _proxyurl = VSMP_Settings.DocumentElement.SelectSingleNode("//VSMP_Proxy_SettingsAtos//ProxyUrl").InnerText;
            var _proxyport = Convert.ToInt32(VSMP_Settings.DocumentElement.SelectSingleNode("//VSMP_Proxy_SettingsAtos//ProxyPort").InnerText);
            //var _proxylogin = VSMP_Settings.DocumentElement.SelectSingleNode("//VSMP_Proxy_Settings//ProxyLogin").InnerText;
            //var _proxypass = VSMP_Settings.DocumentElement.SelectSingleNode("//VSMP_Proxy_Settings//ProxyPass").InnerText;
            var _proxyswitch = Convert.ToBoolean(VSMP_Settings.DocumentElement.SelectSingleNode("//VSMP_Proxy_SettingsAtos//ProxySwitch").InnerText);

            //proxy bypass connection settings
            if (_proxyswitch)
            {
                const SslProtocols _Tls12 = (SslProtocols)0x00000C00;

                const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;

                ServicePointManager.SecurityProtocol = Tls12;
                var proxy = new WebProxy(_proxyurl, _proxyport);
                //proxy.Credentials = new NetworkCredential(_proxylogin, _proxypass);
                WebRequest.DefaultWebProxy = proxy;
                 //HttpWebRequest.DefaultWebProxy = proxy;

            }


        }

    }

i did like this but always i get error
System.AggregateException: One or more errors occurred. (One or more errors occurred. (Unauthorized Http Status Code (401) was expected in the response (Parameter 'response')))

The code that was pasted does not show use of ADAL or MSAL libraries, so I have no idea what that does.

For ADAL support for proxies is done like this: https://github.com/AzureAD/azure-activedirectory-library-for-dotnet/wiki/with-proxy
