AutoMapper

Fast, Flexible Object Mapping for .NET

AutoMapper is a widely used .NET object-mapping library designed to simplify transforming data between models, DTOs, and view models. Instead of writing repetitive, error-prone mapping code by hand, AutoMapper automatically handles member-to-member assignments using clean, maintainable configuration. This allows developers to reduce boilerplate, improve consistency, and accelerate development across complex .NET applications.

Built for high performance and easy integration, AutoMapper supports ASP.NET Core, Web APIs, microservices, domain-driven design, and any architecture where clean separation of layers matters. Its convention-based approach, combined with customizable profiles and resolvers, provides full control over mapping behavior while keeping codebases lightweight and maintainable.

AutoMapper is optimized for production workloads, offering fast execution, strong type safety, and predictable behavior. It's a popular choice for teams who want to reduce mapping overhead, improve code readability, and enforce clear boundaries between domain models and transport objects.
