Dapper is a lightweight micro-ORM for .NET that maps ADO.NET query results to strongly-typed objects. It lets developers execute raw SQL and stored procedures with high performance and minimal boilerplate.
Use cases
- map sql query results to c# objects
- execute raw sql with ado.net without boilerplate
- fast lightweight data access in .net
- call stored procedures and map results
- run parameterized queries safely
- batch multiple queries into one database call
When to choose
- you want raw sql control with object mapping in .NET
- performance matters more than full ORM features
- you want a lightweight alternative to Entity Framework
- you need async and batched query support
When to avoid
- you want change tracking, migrations, or LINQ queries
- you prefer a full-featured ORM generating sql for you
- you are not on a .NET language
