Installation

FxKit is broken up into the following packages:

• FxKit: The core library. Can be used on its own.
• FxKit.CompilerServices: Roslyn analyzers and source generators.
• FxKit.CompilerServices.Annotations: Attributes used by the compiler services.
• FxKit.Testing: Contains test helpers for asserting on the FxKit types.

It is recommended to add the following global using to make it easy to construct the core data types.

global using static FxKit.Prelude;

This makes functions like Some(value) and Ok(value) available everywhere.
