Blazor Server .Net 8 Аутентификация файлов cookie без идентификации ⇐ C#

[Anonymous]

I was trying to do a custom authentication using Blazor Server in .Net 8 but until now not succeed. I'm new to this Blazor framework and please check my work flow why I keep getting the error. I've read some of the article but things in Blazor are moving so fast and I've tried so many method but still unsuccessful.

P/S: If my question is duplicate feel free to comment for removal.

Thanks in advanced!
