PolyType

PolyType is a practical generic programming library for .NET. It facilitates the rapid development of feature-complete, high-performance libraries that interact with user-defined types. This includes serializers, structured loggers, mappers, validators, parsers, random generators, and equality comparers. Its built-in source generator ensures that any library built on top of PolyType gets Native AOT support for free.

The project is a port of the TypeShape library for F#, adapted to patterns and idioms available in C#. The name PolyType is a reference to polytypic programming, another term for generic programming.

See the project website for additional background and API documentation.
