Not yet, as I don't understand what changes do I need to implement in the syntax. As I also said, this class as is already used in our application and I don't want to change all individual calls. My last idea was to create another class based on this one where I would introduce the second class.

Can you help me a bit with the syntax assuming I'll go this route?

Say, here is the current implementation of this class for GuestsRepository:

 public class GuestsRepository : RepositoryBase<Guests>, IGuestsRepository
    {
        public GuestsRepository(ISiriusSqlContext context) : base(context)
        {

        }

For GuestsRepository I want to have another class (GuestsList). For most of the other classes I am OK with the current implementation.
