  Do it in your application service. This is how aspnetboilerplate does it:

  public virtual async Task<IdentityResult> CheckDuplicateUsernameOrEmailAddressAsync(long? expectedUserId, string userName, string emailAddress)
  {
      var user = (await FindByNameAsync(userName));
      if (user != null && user.Id != expectedUserId)
      {
          throw new UserFriendlyException(string.Format(L("Identity.DuplicateUserName"), userName));
      }
  
      user = (await FindByEmailAsync(emailAddress));
      if (user != null && user.Id != expectedUserId)
      {
          throw new UserFriendlyException(string.Format(L("Identity.DuplicateEmail"), emailAddress));
      }
  
      return IdentityResult.Success;
  }
