C#: Create a new user

Creates a new user.

• SignUp() returns a Session. Inspect Session.User to determine the outcome; an empty Session.User.Identities list indicates the account already existed.
• By default, the user needs to verify their email address before logging in. To turn this off, disable Confirm email in your project.
• Confirm email determines if users need to confirm their email address after signing up.
  • If Confirm email is enabled, the returned user is unconfirmed (Session.User.ConfirmedAt is null and Session.User.ConfirmationSentAt is set) and the client is not signed in.
  • If Confirm email is disabled, the user is auto-confirmed, the returned Session is adopted as the current session, and a SignedIn state change fires.
• When the user confirms their email address, they are redirected to the SITE_URL by default. You can modify your SITE_URL or add additional redirect URLs in your project.
• If SignUp() is called for an existing confirmed user, GoTrue avoids revealing that the account exists, so the outcome depends on your project's settings:
  • When both Confirm email and Confirm phone (even when phone provider is disabled) are enabled in your project, a Session is returned whose Session.User.Identities list is empty (an obfuscated user; no new account was created).
  • When either Confirm email or Confirm phone (even when phone provider is disabled) is disabled, a GotrueException with the message User already registered is thrown.

Examples
