AutoMapper is a strongly typed object-to-object mapper for .NET. It provides utilities for copying data between different object representations using convention-based property matching to eliminate manual assignment code.
The library automates the transformation of data models by matching source and destination properties based on shared names and types. It supports the conversion of internal domain models into data transfer objects, facilitating data movement between presentation, business, and data access layers.
The system employs reflection-based type discovery and recursive object graph traversal to process nested hierarchies. It includes capabilities for flattening nested source properties into single destination properties and utilizes cached mapping plans to store pre-computed transformation logic.
