How to use IRegister in asp.net 4.7.2 projects?

[netty2019]

My project is asp.net 4.7.2 MVC, Mapster version 7.2.0

Configuring IRegister does not work

public class HjCollectDtlMapper : IRegister
{
    public void Register(TypeAdapterConfig config)
    {
        config.ForType<SaveDtlInput, HjCollectDtl>()
            .Map(u => u.IsManual, p => p.IsManual ? "Y" : "N");
    }
}

Do you scan for IRegister types at the startup?

TypeAdapterConfig.GlobalSettings.Scan(typeof(HjCollectDtlMapper).Assembly);

Or add them explicitly?

TypeAdapterConfig.GlobalSettings.Apply(new HjCollectDtlMapper());
