## What it is
PetaPoco is a tiny, fast, dependency-free micro-ORM for .NET that maps database rows to POCO objects using dynamic MSIL method generation. It supports sync and async operations, dynamic Expando objects, and multiple database providers.

## Use cases
- map sql query results to poco objects in .net
- lightweight data access without a full orm like entity framework
- run async database queries in c#
- work with dynamic expando rows from a database
- generate poco classes from database tables

## When to choose
- you want a tiny, zero-dependency data mapper for .net
- you need dapper-like performance with simple poco mapping
- your project targets netstandard 2.0 or legacy .NET 4.x

## When to avoid
- you need a full-featured ORM with change tracking, migrations, and LINQ query translation
- you prefer code-first entity modeling with rich relationship support

## Facets
- artifact type: library
- maturity: active
- function: orm, database, database-driver
- domain: databases, backend, developer-tools
- platform: dotnet, cross-platform
- tags: micro-orm, poco, csharp, nuget, sql, netstandard
