MSMapper

CI NuGet License: MIT

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;
});
