C# SAML Signature Verification

I'm trying to replicate a behavior of SAMl signature verification from one of the system into C# and I'm trying locally on my system. However, I'm not able to crack it so far, I always get false when I try to verify the signed XML with X509 certificate.
What am I missing, and is there a way to get logs to explain why it is failing?
public static bool VerifyXml(XmlDocument Doc,X509Certificate2 cert1) {
if (Doc == null)
throw new ArgumentException("Doc");
SignedXml signedXml = new SignedXml(Doc);
var nsManager = new XmlNamespaceManager(Doc.NameTable);
nsManager.AddNamespace("ds", "http://www.w3.org/2000/09/xmldsig#");
var node = Doc.SelectSingleNode("//ds:Signature", nsManager);
// find signature node
var certElement = Doc.SelectSingleNode("//ds:X509Certificate", nsManager);
// find certificate node
var cert = new X509Certificate2(Convert.FromBase64String(certElement.InnerText));
signedXml.LoadXml((XmlElement)node);
if (cert1.GetPublicKeyString() != cert.GetPublicKeyString())
{
Console.WriteLine("certificate verification failed.");
return false;
}
return signedXml.CheckSignature(cert);
}
Below is the SAML Response that I'm trying to verify, I have trimmed some data for security reasons:

Adding wsse:Security token with message signature

I am trying to send a request via web service (SoapHttpClientProtocol) method. Unfortunately for me, this request requires to have wsse:Security Token in soap header, with signature of request xml, and raw data of public key (as I understand).
Soap exammple how it should be:

What I have done:
Created class
public class SecurityHeader : SoapHeader, IXmlSerializable
{
public XmlElement Xml { get; set; }
public XmlSchema GetSchema()
{
return null;
}
public void ReadXml(XmlReader reader) { }
public void WriteXml(XmlWriter writer)
{
writer.WriteRaw(Xml.InnerXml);
}
}
added class which adds SecurityHeader
SecurityHeaderExtension : SoapExtension
into web.config:
<system.web>
</system.web>
And finally I am getting soap:Header <wsse_x003A_Security ...> instead of soap:Header <wsse:Security ...>
Can somebody give me a hand of help? I have read a lot links already, with no result at the moment...
UPD:
Partialy solved this issue by:
var requestContext = myWebService.RequestSoapContext;
var token = new Microsoft.Web.Services2.Security.Tokens.X509SecurityToken(certX);
requestContext.Security.Tokens.Add(token);
requestContext.Security.Timestamp.TtlInSeconds = 5;
// Sign the message using the X509 certificate.
var messageSign = new Microsoft.Web.Services2.Security.MessageSignature(token);
messageSign.SignatureOptions = Microsoft.Web.Services2.Security.SignatureOptions.IncludeSoapBody | Microsoft.Web.Services2.Security.SignatureOptions.IncludeTimestamp;
requestContext.Security.Elements.Add(messageSign);
var resp = myWebService.ExecuteCall(req);
Now I have problem with reading response, I am getting error: 'The signature or decryption was invalid'.
As I understand the problem is on my side, but not sure...

I need a "BinarySecurityToken" when I call "SOAP Service" using ".Net Core"

I want to create something like below:
<SOAP-ENV:Header>
<wsse:Security SOAP-ENV:mustUnderstand="1">
<wsse:BinarySecurityToken EncodingType="…#Base64Binary" ValueType="…#X509v3" wsu:Id="CertId-1776694">

I have the next code:
OperationsClient client = new OperationsClient();
var response = await client.MarketInfoAsync(request);
...
internal partial class OperationsClient
{
static partial void ConfigureEndpoint(ServiceEndpoint serviceEndpoint, ClientCredentials clientCredentials)
{
serviceEndpoint.Address = new EndpointAddress("https://testmisapi.ercot.com/2007-08/Nodal/eEDS/EWS/");
(serviceEndpoint.Binding as BasicHttpBinding).Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
(serviceEndpoint.Binding as BasicHttpBinding).Security.Mode = BasicHttpSecurityMode.Transport;
clientCredentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, 509FindType.FindBySerialNumber, "XXXXX");
}
}
I recieve the error:
SECU1075: An error was discovered processing the <wsse:Security> header
I have tried changig this:
(serviceEndpoint.Binding as BasicHttpBinding).Security.Mode = BasicHttpSecurityMode.TransportWithMessageCredential;
(serviceEndpoint.Binding as BasicHttpBinding).Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.Certificate;
But in this case I recieve following error:
Could not establish trust relationship for the SSL/TLS secure channel with authority 'testmisapi.ercot.com'.
I have read that I can use IClientMessageInspector but I don't know how can I add the complete Security header.
Thank you very much!

Signature xml tags in another position

I'm doing the signing of a document with c #
  with this code
public class program
{
static void Main(String[] arg)
{
string xmlString = File.ReadAllText(#"D:\E-Billing\Demo.xml");
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlString);
//doc.Load(#"D:\E-Billing\Demo.xml");
string pfxStr = #"D:\E-Billing\jojolete.pfx";
X509Certificate2 cert = new X509Certificate2(File.ReadAllBytes(pfxStr),"cabanillas");
SignedXMLWithCertificate(doc, cert);
Console.WriteLine(doc.OuterXml);
doc.Save(#"D:\E-Billing\Demo2.xml");
}
public static void SignedXMLWithCertificate(XmlDocument doc, X509Certificate2 cert)
{
SignedXml signedXML = new SignedXml(doc);
signedXML.SigningKey = cert.PrivateKey;
Reference reference = new Reference();
reference.Uri = "";
reference.AddTransform(new XmlDsigEnvelopedSignatureTransform());
signedXML.AddReference(reference);
KeyInfo keyinfo = new KeyInfo();
keyinfo.AddClause(new KeyInfoX509Data(cert));
signedXML.KeyInfo = keyinfo;
signedXML.ComputeSignature();
XmlElement xmlsig = signedXML.GetXml();
//doc.DocumentElement.AppendChild(doc.ImportNode(xmlsig, true));
XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("ext", "");
doc.SelectSingleNode("/Invoice/ext:ExtensionContent", nsmgr).AppendChild(doc.ImportNode(xmlsig, true));
}
Xml document I want to sign has the following tags where to insert the signature

As I can move or assign where they will sign the xml?

You can change the last line of your code
doc.DocumentElement.AppendChild(doc.ImportNode(xmlsig, true));
to
doc.SelectSingleNode("/Invoice/ext:ExtensionContent", nsmgr).AppendChild(doc.ImportNode(xmlsig, true));
The document node is the root node, so it will append there. SelectSingleNode() uses XPath to select a different node for importing. Note that you need a namespace manager for the extprefix.
XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("ext","uri-of-ext");

Validate xml signature with X509DATA and RSAKeyValue

I have a program that needs to validate xml signatures, I have not had any troubles until a provider sent me one xml with a strange format and my code couldn't validate it's signature.
public bool Validate(XmlDocument p_doc)
{
XmlNamespaceManager l_nsManager = new XmlNamespaceManager(new NameTable());
l_nsManager.AddNamespace("ds", "http://www.w3.org/2000/09/xmldsig#");
XmlElement l_signatureElement = p_doc.SelectSingleNode("//ds:Signature", l_nsManager) as XmlElement;
SignedXml l_signed = new SignedXml(p_doc);
l_signed.LoadXml(l_signatureElement);
return l_signed.CheckSignature();
}
The method CheckSignature returns false, and I know it is a valid document.
The xml I am trying to validate:
