Top 20 NuGet maybe Packages

Option types for C# with LINQ support and rich fluent syntax for many popular uses: var maybeOne = "one".ToMaybe(); Maybe<string> maybeAnother; var maybeBoth = from one in maybeOne from another in maybeAnother select one + another; maybeBoth.Match( both => Console.WriteLine("...
Optional is a robust option/maybe type for C#.
This package includes implementation of Maybe, Try, Either with set of utility extension methods.
SoftwareCraft.Maybe represents the OOP implementation of a functional concept. Instead of returning null, return a Maybe, and the code will be much cleaner and the intent much clearer.
A collection of useful types and operations on types.
This project provides the monads Maybe(of T) and Try(of T), both with full support for modern async/await code.
Yet another Maybe! This Maybe is an immutable monad type with enhancements for functional programming in C#. It implements several IEquatable and IComparable to nestle smoothly into existing code.
.NET library that provide mainly functional features for C#. This means concept of Option, Result, Either and ValueObject. Supported platforms: - .NET Standard 1.0+ - .NET Core 1.0+ - .NET Framework 2.0+ Supports Source Link

Useful Optional extensions for working with collections.
A lightweight wrapper type for optional values.
Function programming goodness: algebraic structures, Maybe, Either, Unit, State, Writer, Functor, Monad, Monoid, Lenses, and more.
Json converter for error-less serialization of Maybe type when using Newtonsoft.Json. Just add MaybeConverter to your list of Json converters.
The library for things that may or may not exist. Existential is a utility library that contains parameter validation methods, a Maybe monad, and more. It can be used to work effectively with nulls, to efficiently resolve Code Analysis issues CA1062 and CA2000, to help generate a hash code, and to ...
A set of assertions for FluentAssertions which provides strong-typed assertions for instances of Optional.
Implements an option type (Strilanc.Value.May<T>) that encourages usage based on pattern matching rather than ForceGetValue. Also includes utility methods for producing, consuming and transforming May<T>. Note on null: May<T> treats null like any other value. May.NoValue is distinct from null, and ...
Features implementations of some of the usual suspects from functional programming: option type (Maybe<T>), error types (Result<T, TError>, Outcome<T> and Fallible<T>) for Railway Oriented Programming, simple disjoint union (Either<T1, T2>), (finite and infinite) sequence generators and LINQ extensi...
Async extensions for Nils Lück's Optional library.
