Asp.Net MVC7 email verification

Hello, i’m quite new and an old developer that is starting again just for fun.
I’m tring to use email verification and i’m confused and scared about email verification.
If i set ia rule email verification it works but when i land to my app i got en error.

what i’d like to do, please correct me if i’m wrong, is:

  • set email verification via action (and i don’t find a simple guide for that that redirect to a landing page to prompt the user the step)
  • do not redirect to my callback if the email is not verified
  • redirect via action to a page (better gui on auth0) for resending the email verification

is few days that i try to find a solution and this simple use case is not present in any guide that i’ve read.
