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
