## What it is
MoreLINQ is a C# library that extends LINQ to Objects with additional extension methods for IEnumerable<T>, such as Batch, DistinctBy, MaxBy, and Windowed. It is distributed as a NuGet package and keeps to the design spirit of standard LINQ.

## Use cases
- batch an IEnumerable into fixed-size chunks in C#
- find the max element by a key selector without sorting
- window or slide over a sequence in .NET
- get distinct elements by a specific property in LINQ
- zip sequences of different lengths in C#
- take every nth element from a collection

## When to choose
- you write .NET/C# code and want richer sequence operators than the built-in LINQ provides
- you want a lightweight, dependency-free NuGet package that follows LINQ conventions
- you need well-documented, battle-tested IEnumerable extensions

## When to avoid
- you work outside the .NET ecosystem
- you only need one or two simple helpers that are trivial to write yourself
- you need async/IAsyncEnumerable extensions, which this library does not focus on

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools
- domain: developer-tools, programming-languages
- platform: dotnet, cross-platform
- tags: linq, csharp, ienumerable, extension-methods, nuget
