I have updated ComponentSpace library 2.6.0.7 -> 3.1. I also updated target framework 4.6.1 to 4.7.1
This is the only change which started throw exception in this line
SAMLMessageSignature.Generate(samlResponseXml, cert.PrivateKey, cert);
Message: ComponentSpace.SAML2.Exceptions.SAMLSignatureException : Failed to generate the XML signature.
----> System.Security.Cryptography.CryptographicException : Invalid algorithm specified.
Same certificate is used.
What is wrong?
