Dapper Extensions is a small library that complements Dapper by adding basic CRUD operations (Get, Insert, Update, Delete) for your POCOs. For more advanced querying scenarios, Dapper Extensions provides a predicate system. The goal of this library is to keep your POCOs pure by not requiring any attributes or base class inheritance. observed · 2026-08-28

Dapper Extensions is a small .NET library that complements Dapper by adding automatic CRUD operations (Get, Insert, Update, Delete) for POCOs, plus a predicate system for advanced queries. It keeps POCOs pure by requiring no attributes or base class inheritance, using ClassMapper for customized entity-table mappings.

Use cases

add crud operations to dapper without writing sql
map poco classes to database tables without attributes
query database with predicate system instead of raw sql
get paged result sets from database in .net
support composite primary keys with dapper
count and list entities with a micro-orm

When to choose

you already use Dapper and want automatic CRUD without heavy ORM overhead
you need attribute-free POCOs with customizable table mappings
you want lightweight querying with predicates and paging on SQL Server, MySQL, SQLite, or PostgreSQL

When to avoid

you need a full ORM with change tracking, lazy loading, or migrations
you prefer Dapper.Contrib or an attribute-based mapping approach
you need a project with an explicit license or very active development
