--- UPDATE---
--- This post is possibly a duplicate one since my account StackOverflow is somehow restarted today ---
I already post this question as https://superuser.com/questions/1662866/windows-credential-provider-not-shown-in-21h1
But The only reply that I have is
sounds more like a Stack Overflow question at this point
I already make sure that all DLL is well prepared Custom Credential Provider not loading
Also I already make sure that all registry is also set https://www.thewindowsclub.com/custom-credential-providers-fails-to-load
Can anyone tell me what should I do?
Well, it turns out we need the Microsoft Visual Studio C++ redistribute to work.
Thanks to swiversecure
I don't know what is the reason why in version 21H1, that package is not included. Therefore, I have to download it first using this link. It is not necessary to restart the pc or reinstall the Credential provider, so I just lock my pc to see result. Then, my custom credential provider just showed up ._.
