Dapper: Simple object mapper for .NET

Dapper is a micro-ORM library that provides extension methods for ADO.NET DbConnection instances to simplify database operations. It works by extending existing database connections with methods like Query<T>(), Execute(), and QuerySingle<T>() that automatically map SQL results to .NET objects. The library uses reflection and compiled expressions to achieve efficient object mapping while maintaining a minimal footprint. It supports both synchronous and asynchronous operations, parameterized queries, and can map to POCOs, dynamic objects, or primitive types.
