The code in c # is as follows

            var b = new NetHttpBinding();
            b.Security.Mode = BasicHttpSecurityMode.Transport;
            b.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
            b.TransferMode = TransferMode.StreamedRequest;
            b.MessageEncoding = NetHttpMessageEncoding.Text;
            Encoding utf8 = new UTF8Encoding();
            b.TextEncoding = utf8;

            EndpointAddress ea = new EndpointAddress("https://endpointtest/WSHttpsSoap12Endpoint/");
          
            
            AutosClonicoWSPortTypeClient clientService = new AutosClonicoWSPortTypeClient(b, ea);

            var requestInterceptor = new InspectorBehavior();
            clientService.Endpoint.EndpointBehaviors.Add(requestInterceptor);
            clientService.ClientCredentials.ClientCertificate.SetCertificate(
                StoreLocation.CurrentUser,
                StoreName.Root,
                X509FindType.FindBySerialNumber,
            "NumberSerial");

            await clientService.OpenAsync();

var res = await clientService.call3Async("<![CDATA[" + "<test><element>exampletest</element></test>" + "]]>");

The contract at the client level is as follows

[System.CodeDom.Compiler.GeneratedCodeAttribute("Microsoft.Tools.ServiceModel.Svcutil", "2.0.2")]
    [System.ServiceModel.ServiceContractAttribute(Namespace="http://example.com", ConfigurationName="ServiceReference2.Example")]
    [XmlSerializerFormat(Style = OperationFormatStyle.Document,
    Use = OperationFormatUse.Literal)]
    public interface ClonicoWSPortType
    {
        
        [System.ServiceModel.OperationContractAttribute(Action="urn:call3", ReplyAction="urn:call3Response")]
        [System.ServiceModel.FaultContractAttribute(typeof(ServiceReference2.ClonicoWSException), Action="urn:call3AutosClonicoWSException", Name="AutosClonicoWSException")]
        [return: System.ServiceModel.MessageParameterAttribute(Name="return")]
        [XmlSerializerFormat(Style = OperationFormatStyle.Document,
      Use = OperationFormatUse.Literal)]
        System.Threading.Tasks.Task<string> call3Async(string xml);
    }

If it has happened to someone else, I appreciate your help, I have tried to apply everything I have found and I have not been able to solve it, thank you very much!
