## What it is
A C# library providing functional programming extensions, including Result and Maybe monads, value objects, and fluent method chaining. It helps C# developers write more functional code by making errors and nulls explicit.

## Use cases
- handle errors without exceptions in C#
- eliminate null reference exceptions with Maybe type
- avoid primitive obsession with value objects
- chain operations in a functional pipeline
- implement railway-oriented programming in .NET
- make method failure states explicit in C#

## When to choose
- you write C# and want Result/Maybe types for explicit error handling
- you want to reduce null checks and exceptions in .NET code
- you prefer fluent, composable operation chains over imperative control flow

## When to avoid
- your team is unfamiliar with functional programming concepts
- you work outside the .NET/C# ecosystem
- you need a full functional programming language rather than extensions

## Facets
- artifact type: library
- maturity: stable
- function: error-handling, serialization
- domain: programming-languages, developer-tools
- platform: dotnet, cross-platform
- tags: functional-programming, result-monad, maybe-monad, value-objects, csharp, railway-oriented-programming, algorithms
