Verify detached signature of empty file does not work

[Alexey2040]

I have a problem when verifying detached signature of empty file.

private static bool VerifyDetachedSignature(byte[] fileRawBytes, string sign)
    {
        try
        {
            var signatureFileRawBytes = Convert.FromBase64String(sign);
            var cms = new CmsSignedData(new CmsProcessableByteArray(fileRawBytes), signatureFileRawBytes);
            var signers = cms.GetSignerInfos();

            var certificates = cms.GetCertificates("Collection");
            var signerInfos = signers.GetSigners();
            foreach (SignerInformation signer in signerInfos)
            {
                var certList = new ArrayList(certificates.GetMatches(signer.SignerID));
                var cert = (X509Certificate)certList[0];
                if (cert == null) throw new NullReferenceException();

                var publicKey = cert.GetPublicKey();

                signer.Verify(publicKey);
            }

            return true;
        }
        catch (Exception exception)
        {
            return false;
        }
    }

On signer.Verify(publicKey); it throws an exception:

Message:'message-digest attribute value does not match calculated value' StackTrace: at Org.BouncyCastle.Cms.SignerInformation.DoVerify(AsymmetricKeyParameter key) at Org.BouncyCastle.Cms.SignerInformation.Verify(AsymmetricKeyParameter pubKey) at myProject.Controllers.Controller.VerifyDetachedSignature(Byte[] fileRawBytes, String sign) ...

I assume problem is that empty byte array passed to new CmsProcessableByteArray(fileRawBytes), so there no copy of signed data passed to CmsSignedData. Is there work around?
