#region To handle TLS (Transport Layer Security) Version and support
            var assembly = Assembly.GetExecutingAssembly();
            var attributes = assembly.GetCustomAttributes(typeof(TargetFrameworkAttribute), false);
            var version = (TargetFrameworkAttribute)attributes[0];

            SecurityProtocolType flag;
            if (Enum.TryParse("Tls11", out flag))
                ServicePointManager.SecurityProtocol |= flag;
            if (Enum.TryParse("Tls12", out flag))
                ServicePointManager.SecurityProtocol |= flag;
#endregion
