SignedCms.CheckSignature - 'LibCore.Common.Reflection.Reflector' does not contain a definition for 'GetContent'"

[k0st1x]

Здравствуйте, хочу использовать механизм проверки подписи. Взял код из https://github.com/CryptoPro/libcore#readme

// Декодируем подпись
signedCmsVerify.Decode(signature);

// Проверяем подпись
signedCmsVerify.CheckSignature(true);

(под windows) получаю падение:

Помогите разорбраться с работоспособностью примера.

upd: Под отладчиком видно, что объект "instance" является типом "SignerInfo", которого нет публичного метода "GetDigestAlgorithm()".

Добрый день.

Для начала, в рамках паранойи, предлагаю убедиться, что это не внутренне исключение, которое перехватывает студия, ибо выставлена галка перехватывать все исключения.

Если поведение наблюдаете под отладчиком - и игнорировать данное исключение (нажимая f5 при его возникновении, или поставив галку на его дальнейший игнор в студии) или же запускать без отладчика - код завершается успешно для вызывающей функции?

@Fasjeit спасибо за уточнение. Я дополню. Действительно, то что я написал в изначальном тексте было про "GetDigestAlgorithm()" если я сделаю код

try {
  signedCms.CheckSignature(true);
} catch(Exception e) { } // !!!

то приложение попадет в catch вот с таким исключением

Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'LibCore.Common.Reflection.Reflector' does not contain a definition for 'GetContent'

   at System.Security.Cryptography.Pkcs.SignedCms.CheckSignature(X509Certificate2Collection extraStore, Boolean verifySignatureOnly)
   at System.Security.Cryptography.Pkcs.SignedCms.CheckSignature(Boolean verifySignatureOnly)

Видно, что в итоге падение ругается на отсутствие метода "GetContent()".

@Fasjeit спасибо за быстрый ответ. С новым пакетом ошибка в блоке catch отлавливается, но выглядит уже вот так:

@Fasjeit Спасибо, теперь работает. Как можно получить билд для Linux?
