steps i do is

1- generate basic invoice
2-GenerateInvoiceHash(xmlInvoice);

3-AddUBLExtensions(xmlInvoice, _hash.Hash, );

4- SignGeneratedInvoiceHash(updatedXml.OuterXml);

5-add hash to invoice

XmlNamespaceManager nsmgr = new XmlNamespaceManager(updatedXml.NameTable);
nsmgr.AddNamespace(“ext”, “urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2”);
nsmgr.AddNamespace(“sig”, “urn:oasis:names:specification:ubl:schema:xsd:CommonSignatureComponents-2”);
nsmgr.AddNamespace(“sac”, “urn:oasis:names:specification:ubl:schema:xsd:SignatureAggregateComponents-2”);
nsmgr.AddNamespace(“ds”, “http://www.w3.org/2000/09/xmldsig#”);
XmlNodeList lst = updatedXml.SelectNodes(“//ext:UBLExtensions/ext:UBLExtension/ext:ExtensionContent/sig:UBLDocumentSignatures/sac:SignatureInformation/ds:Signature/ds:SignedInfo/ds:Reference[@URI=‘#xadesSignedProperties’]/ds:DigestValue”, nsmgr);

XmlNode dig = lst[0];
dig.InnerText = _Fsign.Steps.Where(x=>x.StepName== “Populate Signed Signature Properties”).FirstOrDefault().ResultedValue;

XmlNode SignatureValue = updatedXml.GetElementsByTagName(“ds:SignatureValue”).Item(0);

SignatureValue.InnerText= _Fsign.Steps.Where(x => x.StepName == “Generate Signature”).FirstOrDefault().ResultedValue;

XmlNode KeyInfo = updatedXml.GetElementsByTagName(“ds:X509Certificate”).Item(0);

KeyInfo.InnerText = _Fsign.Steps.Where(x => x.StepName == “Parse Certificate”).FirstOrDefault().ResultedValue;

6- CreateAdditionalDocumentReferences(updatedXml.OuterXml,bill, _hash.Hash) which contain the QR Generation
