Breaking Changes

Required package: Dapper.FluentMap

Review behavior and package differences that can affect an upgrade.

Use this capability when the column shape and .NET model should remain separated by explicit, reviewable configuration.

public sealed class CustomerMap : EntityMap<Customer>
{
public CustomerMap()
{
Map(x => x.Id).ToColumn("customer_id");
Map(x => x.Name).ToColumn("customer_name");
}
}

FluentMap registers typed metadata and applies it through the matching materialization path. SQL, connections, parameters, and lifecycle remain responsibilities of the application and Dapper.
