ImplementInterface() is not recursive

[DuAell]

ImplementInterface only detects types that directly implements the interface, but won't detect if interface is declared on parent type.

public interface IHandler;

public class ParentHandler : IHandler;

public class ChildHandler : ParentHandler <= Won't be detected by Types.That().ImplementInterface(typeof(IHandler))

It works as expected, and the default behavior remains unchanged.

As an enhancement, we could consider supporting a recursive version—either by introducing a new set of predicates/conditions or by adding a parameter to the existing ImplementInterface().

A more practical example, where CreateCommand and UpdateCommand are not detected as they do not directly implement ICommand<Session>

    public abstract record Command(
        Guid UserId) : ICommand<Session>;

    public sealed record CreateCommand(
        Guid UserId) : Command(UserId);

    public sealed record UpdateCommand(
        Guid SessionId,
        Guid UserId) : Command(UserId);
