Consider to create aggregate roots via a factory class in the pre-built modules

Example:

public class IdentityUserFactory : DomainService, IIdentityUserFactory
{
    public virtual Task<IdentityUser> CreateAsync(
        [NotNull] string userName,
        [NotNull] string email)
    {
        var user = new IdentityUser(
            GuidGenerator.Create(),
            userName,
            email,
            CurrentTenant.Id
        );

        return Task.FromResult(user);
    }
}

This gived oppurtunity to override the factory method and perform custom logic while creating the aggregate root.
