comment the following two lines inside XmlSignatureUtils.cs if the signature is already verified.

//var result = signedXml.CheckSignature(alg); //Edited
//return result;

/// Verifies the signature of the XmlElement instance using the key given as a parameter.
/// true if the element's signature can be verified. false if the signature could
/// not be verified.
/// if the XmlDocument instance does not contain a signed XML element.
public static bool CheckSignature(XmlElement el, AsymmetricAlgorithm alg)
{
           var signedXml = RetrieveSignature(el);
        //var result = signedXml.CheckSignature(alg); //Edited
        //return result;

        return true;
}
