Username disallows using "-"

[p10tyr]

Why is it not allowed to use a dash "-" in the username?

   var user = new Models.ApplicationUser(userEmail);
   var result = await UserManager.CreateAsync(user, password);

Exception

Creating user Failed. User name my.name@the-gym.com is invalid, can only contain letters or digits.

Exception Details: System.Web.HttpException: Creating user Failed. User namemy.name@the-gym.com is invalid, can only contain letters or digits.

When I go into RavenDB management panel, I can change the Key manually to include the "-" and the username is just a string.

I checked the source code.. its not your fault.

It is the ASP UserManger causing hell. Use this line when adding a new user then will work as normal throughout the project. (You can get that username without setting the validitor, I mean.)

UserManager.UserValidator = new UserValidator<Models.ApplicationUser>(UserManager) { AllowOnlyAlphanumericUserNames = false };
