Mapping samples

Select one delegate near the top of Program.cs, then run:

dotnet run --project mapping/samples/Valiant.Mapping.Samples

Program.cs is intentionally only a selector. Each folder is self-contained, and the Sample class owns the explanation of the behavior it invokes.

Delegate	Demonstrates	Source
Basic.Sample.Run	The smallest useful mapper: matching members mapped by convention into an immutable constructor target	Basic
ExplicitMapping.Sample.Run	A custom source transform, a renamed target member, and an intentionally ignored target member	ExplicitMapping
ConditionalMapping.Sample.Run	Native if/else, a chained When condition, and the equivalent Fallback and Default APIs	ConditionalMapping
NullHandling.Sample.Run	Mapper-wide null policy, IgnoreNull, MapNull, AllowNull, and a fallback for an ignored null	NullHandling
FlatteningAndEnums.Sample.Run	Convention-based flattening, unflattening, and compatible enum conversion	FlatteningAndEnums
Composition.Sample.Run	Constructor-injected mapper reuse for a nested object and collection elements	Composition
DependencyInjection.Sample.Run	Generated registration; typed mapper, non-generic facade, and factory; successful and missing Try APIs	DependencyInjection

The basic and convention samples show what the generator can infer. Samples with a Configure override demonstrate behavior supported by both the debuggable runtime backend and the fast generated backend. The dependency injection sample leaves ValiantMappingMode.Auto selected, so Debug builds use the debuggable backend and Release builds use generated fast mapping.

Continue with Convention mapping, Explicit mapping, or Composition and dependency injection for the complete contracts and constraints.
