Dapper is presented as a focused micro ORM that maps SQL result sets to C# objects with gutsy practical demos using AdventureWorks and SqlClient The demo returns 19,000 rows automatically mapped, filters to 60 Kevins via parameterized where clauses, shows inserts in a loop of 10,000, calls stored procedures by setting CommandType, and demonstrates transactions that require manually opening the connection Uses query async / execute async and dynamic parameters and everything shown runs end to end during the session
