Like Dapper, Dapper Plus is a NuGet library where you can add to your project that will extend your IDbConnection and IDbTransaction interface with high efficient Bulk Actions Helpers (Insert, Update, Delete, and Merge).
It can be used with or without Dapper, and it's compatible with all other Dapper packages.
// CONFIGURE & MAP entity
DapperPlusManager.Entity<Order>().Table("Orders").Identity(x => x.ID);
// CHAIN & SAVE entity
connection.BulkInsert(orders)
.AlsoInsert(order => order.Items);
.Include(order => order.ThenMerge(order => order.Invoice)
.AlsoMerge(invoice => invoice.Items))
.AlsoMerge(order => order.ShippingAddress);

Dapper Plus - Mapper
Dapper Plus Mapper allows to map the conceptual model (Entity) with the storage model (Database) and configure options to perform Bulk Actions.
DapperPlusManager.Entity<Order>().Table("Orders")
.Identity(x => x.ID)
.BatchSize(200);Bulk Actions allow to perform a bulk insert, update, delete or merge and include related child items.
connection.BulkInsert(orders, order => order.Items)
.BulkInsert(invoices, invoice => invoice.Items)
.BulkMerge(shippingAddresses);Also Bulk Actions allow to perform bulk action with a lambda expression using entities from the last Bulk[Action] or ThenBulk[Action] used.
connection.BulkInsert(orders)
.AlsoInsert(order => order.Items)
.AlsoInsert(order => order.Invoice)
.AlsoInsert(order => order.Invoice.Items);Then Bulk Actions is similar to Also Bulk Actions but modifies entities used for the next bulk action using a lambda expression.
connection.BulkInsert(orders)
.AlsoInsert(order => order.Items)
.ThenInsert(order => order.Invoice)
.ThenInsert(invoice => invoice.Items);The Dapper Plus Include method allows resolving issues with multiple "ThenBulk[Action]" methods.
connection.BulkInsert(orders)
.Include(x => x.ThenInsert(order => order.Items)
.ThenInsert(orderItem => orderItem.Metas))
.Include(x => x.ThenInsert(order => order.Invoice)
.ThenInsert(Invoice => invoice.Items)); All Dapper Plus extension methods are also available on the IDbTransaction interface
transaction.BulkInsert(orders)
.Include(x => x.ThenInsert(order => order.Items)
.ThenInsert(orderItem => orderItem.Metas))
.Include(x => x.ThenInsert(order => order.Invoice)
.ThenInsert(Invoice => invoice.Items)); All major database providers are supported or under development.
