LINQ to Objects is missing a few desirable features.
This project enhances LINQ to Objects with extra methods, in a manner which keeps to the spirit of LINQ.
MoreLINQ is available for download and installation as NuGet packages.
Documentation for the stable and beta releases can be found at morelinq.github.io.
