Inserting an entity with TenantId in abp.io framework

Question

I have an entity below that, when I create, inserts with TenantId null. Is it necessary to use CurrentTenant.Id to set TenantId manually?

public class Hall : AuditedAggregateRoot<Guid>, IMultiTenant
{
    public string Name { get; set; }
    public string Location { get; set; }
    public string Explanation { get; set; }
    public Guid? TenantId { get; set; }
}

If you don't inherit from AsyncCrudAppService, then it is necessary to set TenantId yourself.

protected void TryToSetTenantId(TEntity entity)
{
    var tenantId = CurrentTenant.Id;

    if (!tenantId.HasValue)
    {
        return;
    }

    var propertyInfo = entity.GetType().GetProperty(nameof(IMultiTenant.TenantId));

    if (propertyInfo != null && propertyInfo.GetSetMethod() != null)
    {
        propertyInfo.SetValue(entity, tenantId, null);
    }
}

ABP Framework (abp.io) does not limit the case where you may want to create a host or other tenant entity within a tenant scope.
