I am using Aspnet.Identity.EntityFramework 2.2.1
.
I am trying to register a user with the username equal the email leonardo+felipe@gmail.com, however When email has this "+" character, Identity Framework does not allow:
This raises an error where the username field only allows letters and digits, but I need to save an email that has this "+" character. If I remove the "+" character, it is possible to register successfully.
How to override this Identity UserName validation?
