Why does `TemplatesCiclo.List` include values from all subclasses of `Templates` when using Ardalis.SmartEnum?

[art1544]

I’m using [Ardalis.SmartEnum](https://github.com/ardalis/SmartEnum) to model a base enum class and two derived enums:

public abstract class Templates : SmartEnum<Templates> { … }

public class TemplatesCiclo : Templates
{
    public static readonly TemplatesCiclo IdentificadorPedido = new(1, nameof(IdentificadorPedido));
    // … other members …
}

public class TemplatesNotaFiscal : Templates
{
    public static readonly TemplatesNotaFiscal ValorNota = new(9, nameof(ValorNota));
    // … other members …
}

When I iterate over TemplatesCiclo.List, I expected only the TemplatesCiclo instances, but I also get the TemplatesNotaFiscal values:

foreach (var tmpl in TemplatesCiclo.List)
{
    Console.WriteLine(tmpl.Name);
    // Prints both Ciclo members AND NotaFiscal members…
}

• What is causing the child class’s List property to return every instance of the base class (including those from other subclasses)?
• How can I restrict the list so that it only contains the instances defined in TemplatesCiclo?

Any insights into how SmartEnum registers and filters its static instances would be greatly appreciated!
