This package features implementations of some of the usual suspects from functional programming: Option (Maybe<T>) and Error (Output<T>) monads, simple pattern matching (Either<T1, T2>, Switch<T1, T2>), generators and delegate extensions. It also provides a few Code Contracts helpers.

     This is a portable class library targeting Profile259. The behaviour is 100% identical across all supported platforms; this is achieved without making use of the bait and switch PCL trick.

     This library fully passes FxCop, Gendarme and Code Contracts static analysis.

     A code contracts reference assembly is also included if you need it.

There are no supported framework assets in this package.
