Mapping configuration

            cfg.CreateMap(typeof(ModifiableList<>), typeof(List<>))
                    .BeforeMap((a, b) =>//Never called
                    {
                        Type t = a.GetType();
                        if(t == typeof(int))
                        {
                            throw new InvalidOperationException("A is an int");
                        }
                        else
                        {
                            throw new InvalidOperationException("A isn't an int");
                        }
                        return;
                })
                    .ConvertUsing(typeof(ModifiableListConverter<,>))
                    ;

Version: 11.0.1

.NET 6 with automapper 11.0.1

Expected behavior

The BeforeMap callback is called before the TypeConverter

Actual behavior

The BeforeMap callback is not called

That's expected. Type converters don't mix with other configuration. You're, in fact, taking over the mapping.
