Did you actually put "PdfSharp.dll" into "c:\Program Files\Microsoft Dynamics 365 Business Central\140\Service\Add-ins\" folder? Also, try restarting NAV service and Visual Studio

Yeh my PdfSharp.dll was there in that folder, and i knew i had to restart the service but i probably did some mess and maybe i restarted it in some precedent attempt and forgot to restart it when the dll was in the correct folder.
Ty anyway for helping me to realize this, i was almost there 😅
