Fluent

Package 2: Mapsicle.Fluent

Basic Configuration

using Mapsicle.Fluent;

var config = new MapperConfiguration(cfg =>
{
    cfg.CreateMap<User, UserDto>()
        .ForMember(d => d.FullName, opt => opt.MapFrom(s => $"{s.First} {s.Last}"))
        .ForMember(d => d.Password, opt => opt.Ignore())
        .ForMember(d => d.Status, opt => opt.Condition(s => s.IsActive));
});

config.AssertConfigurationIsValid();
var mapper = config.CreateMapper();

DI Integration (NEW!)

// In Program.cs
services.AddMapsicle(cfg =>
{
    cfg.CreateMap<User, UserDto>();
}, validateConfiguration: true);

// In your service
public class UserService(IMapper mapper)
{
    public UserDto GetUser(User user) => mapper.Map<UserDto>(user);
}

Lifecycle Hooks (NEW!)

cfg.CreateMap<Order, OrderDto>()
    .BeforeMap((src, dest) => dest.CreatedAt = DateTime.UtcNow)
    .AfterMap((src, dest) => dest.WasProcessed = true);

Polymorphic Mapping (NEW!)

cfg.CreateMap<Vehicle, VehicleDto>()
    .Include<Car, CarDto>()
    .Include<Truck, TruckDto>();

Custom Construction (NEW!)

cfg.CreateMap<Order, OrderDto>()
    .ConstructUsing(src => OrderFactory.Create(src.Type));

Global Type Converters (NEW!)

cfg.CreateConverter<Money, decimal>(m => m.Amount);
cfg.CreateConverter<Money, string>(m => $"{m.Currency} {m.Amount}");
