Describe the bug
The message for an invalid username is Username '{0}' is invalid, can only contain letters or digits. https://github.com/dotnet/aspnetcore/blob/main/src/Identity/Extensions.Core/src/Resources.resx#L164-L167
However, this message is produced when the username contains any characters not included in AllowedUserNameCharacters, a value which defaults to alphanumeric plus -._@+.
Expected Behavior
At the very least I'd expect the error message reflect what's actually allowed by the defaults. Bonus points if it reflected what's configured by the developer, but this would be quite difficult due to the way that the allowed characters are configured.
Steps To Reproduce
Repro is trivial:
- In an AspNetCore project w/ Identity, call
UserManager<T>.SetUserNameAsync(user, "userName!") - Observe that the error states the username can only contain letters and numbers.
- Change the username to
userName@example.com, observe that no error occurs despite containing characters other than letters and numbers as stated by the validation message.
