Dapper.Mapper is an extension to Dapper multi mapping which figures out the relationships between the returned objects and automatically assigns them. Instead of explicitly writing this: 'var employee = connection.Query<Employee, Department, Employee>(sql, (employee, department) => { employee.Department = department; return employee; });' Dapper.Mapper allows you to write this: 'var employee = connection.Query<Employee, Department>(sql);'.
