kandi X-RAY | Dapper-Extensions Summary
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. Customized mappings are achieved through ClassMapper. Important: This library is a separate effort from Dapper.Contrib (a sub-system of the Dapper project).
