<h1 align="center">Twinify</h1> <p align="center"><b>Object mapping made simple.</b></p>

Twinify copies values from one object to another so you don't have to write that code by hand. Describe the shape of the mapping once, then call Map<T>() wherever you need it.

var dto = mapper.Map<UserDto>(user);

Install

dotnet add package Twinify
dotnet add package Twinify.DependencyInjection

Quick start

1. Describe your mapping in a profile:

public class UserProfile : MappingProfile
{
    public UserProfile()
    {
        CreateMap<User, UserDto>()
            .ForMember(d => d.FullName, opt => opt.MapFrom(s => $"{s.FirstName} {s.LastName}"))
            .ForMember(d => d.Password, opt => opt.Ignore());
    }
}

2. Register it:

builder.Services.AddTwinify(cfg =>
{
    cfg.AddProfile<UserProfile>();
});

3. Use it:

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

That's it - properties with matching names are copied automatically. Anything you want to customize (rename, compute, ignore, convert) gets a line in the profile.

What it handles for you

Auto-matching - properties with the same name copy across without any configuration.
Flattening - a destination property like AddressCity automatically picks up source.Address.City.
Nested objects and collections - lists, arrays, dictionaries, and nested objects map recursively.
Custom logic - ForMember, Ignore, Condition, MapFrom, BeforeMap/AfterMap, ConvertUsing, and more, for the cases that need more than a straight copy.
Constructors and records - Twinify works out how to construct your destination type, including types with only a parameterized constructor.
Explain<TSource, TDestination>() - prints exactly where every destination member's value comes from, for when a mapping doesn't do what you expected.

Packages

Package	What it's for
`Twinify.Abstractions`	The types you write against: `IMapper`, `MappingProfile`, `CreateMap`, etc.
`Twinify`	The mapping engine that actually executes your maps.
`Twinify.DependencyInjection`	`AddTwinify(...)` and friends, for ASP.NET Core / generic host apps.
