MoreLINQ is a library of extension methods that enhances LINQ to Objects with additional operators and sequence-generation capabilities for C#.
LINQ to Objects provides a foundation for querying in-memory collections, but lacks certain useful operations that developers frequently need. MoreLINQ addresses this gap by adding extension methods that operate on IEnumerable<T> types, maintaining the declarative style and composability that characterize LINQ. The library also provides static methods for generating sequences rather than transforming existing ones. To avoid naming conflicts with other libraries or future framework additions, MoreLINQ supports selective importing through C# static imports, allowing developers to bring only the methods they need into scope.
Developers should adopt MoreLINQ if they find themselves repeatedly writing utility functions for sequence manipulation or if they want a richer set of query operators without building custom extensions. The library suits projects of any scale that use LINQ extensively and benefit from operators like Acquire for managing disposable resources, Aggregate variants for complex accumulations, and sequence generators like Unfold and Random. The project is distributed as NuGet packages and includes comprehensive documentation on its homepage.
The project maintains a dev container setup for consistent development environments across platforms. Code generation relies on T4 templates, which developers can regenerate after modifications using platform-specific scripts. Documentation building is supported on Windows through Sandcastle Help File Builder integration. The build system provides cross-platform support through shell scripts for macOS and Linux alongside Windows batch files.
