I\'ve been trying to verify a SAML assertion for the last week an

I've spent a lot of time on this issue and then realized that I am not checking the signature with the right certificate.

So I decided to check the certificate I am receiving in the XML response file from Azure:

signedXml.LoadXml((XmlElement)nodeList[0]);

X509Certificate2 serviceCertificate = null;
foreach (KeyInfoClause clause in signedXml.KeyInfo)
{
    if (clause is KeyInfoX509Data)
    {
        if (((KeyInfoX509Data)clause).Certificates.Count > 0)
        {
            serviceCertificate = (X509Certificate2)((KeyInfoX509Data)clause).Certificates[0];
        }
    }
}

Then:

bool bTest = signedXml.CheckSignature(serviceCertificate , true);

The bTest value was finally set to true.
