MSMapper

MSMapper is a production-grade, high-performance object mapping library for modern .NET. It combines AutoMapper's expressive fluent configuration with compile-time safety and near hand-written performance via expression compilation and incremental source generation.

One configuration model. Three execution engines. Zero surprises in production.

Features

Convention-based mapping between any classes
Fluent configuration API (CreateMap, ForMember, ReverseMap, etc.)
Triple execution engines: Expression, Reflection, and Source Generated
IQueryable projection (ProjectTo) with EF Core translation
Roslyn analyzers for missing mappings and type mismatches
ASP.NET Core DI integration (AddMapper)
Polymorphic mapping, circular reference tracking, flattening
NativeAOT compatible (Generated mode)

Quick Start

dotnet add package MSMapper

using MSMapper;

var config = MapperConfiguration.Create(cfg =>
{
    cfg.CreateMap<User, UserDto>();
    cfg.CreateMap<Product, ProductDto>()
        .ForMember(d => d.Name, s => s.Title)
        .Ignore(d => d.CreatedAt);
});

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

ASP.NET Core

builder.Services.AddMapper(options =>
{
    options.AddMaps(typeof(Program).Assembly);
    options.ValidateOnStartup = true;
});
