I installed NPOI from NuGet, version 2.1.3. I want to read an encrypted excel file. For this purpose, in accordance with this thread, I need to use the EncryptionInfo class from the NPOI.POIFS.Crypt namespace . But my assembly does not contain this namespace.
If you look at the GitHub repository for this library, you will see this namespace in version 2.1.3.
What is my mistake?
PS sorry for my english
