Verify Digital Signature using groupdocs signatures C#

Question

I want to verify digital signatures of my customers using groupdocs Signature, here I am using This Link to get proper code, but the problem is when I initialize GroupDocs.Signature.Signature signature = new Signature("sample_signed.pdf"); I Am getting the error

CS0234 C# The type or namespace 'Signature' does not exist in the namespace 'GroupDocs.Signature' (are you missing an assembly reference?)

My groupdocs version is 19.6, what can I do to verify my digital signatures?

Answer 1

You are using an older version of the API. Please try to use the latest version 21.2 and you won't face this issue. Furthermore, have a look at these migration notes.
