Implicit Mapping

Attribute-free mapping for class names, columns, keys, and types, configured entirely through mapper classes.

FluentMapper

For entities you’d rather not decorate with attributes, FluentMapper configures the table name, keys, columns, database types, and handlers in one chained call.

FluentMapper
    .Entity<Customer>()
    .Table("[sales].[Customer]")
    .Primary(e => e.Id)
    .Identity(e => e.Id)
    .Column(e => e.FirstName, "[FName]");

The individual mappers

FluentMapper is a wrapper over dedicated mapper classes — ClassMapper, IdentityMapper, PrimaryMapper, PropertyMapper, and TypeMapper — each with its own Add(), Get(), and Remove() methods, usable directly when you only need to touch one concern.

Removing a mapping

Every mapper’s Remove() reverses its own Add(). For hot paths, prefer the matching cache class (ClassMappedNameCache, IdentityCache, PrimaryCache, and so on) over calling Get() repeatedly, since the cache avoids re-resolving the same mapping on every call.
