Hi All, I've just release a FOS rewrite of LINQ up onto git. I hope to keep this as a community driven project, and perhaps expand it into other aspects of .Net that are either slow due to GC, or flat out do not work due to AOT/IL2CPP. https://github.com/sootie8/Unity-LINQ Currently most of the LINQ feature set is implemented with significant performance improvements across the board. There are a couple of areas I am looking to improve upon in my next iteration, such as removing the last LINQ dependency with the group-by extension method. Anyway thanks for reading, and feel free to make pull requests and/or suggestions below.
