# Experiments
|
||||
|
||||
This repository contains various experiments and prototypes that I've developed over time. These generally entail nothing more than a ton of benchmarks, and a few various tests of language and framework features, and for the most part are not really usable in any way.
|
||||
|
||||
Alas, I've made this repository open source and added any and all "fuck around and find out" projects I've written over the years. Maybe it'll help people learn something new.
|
||||
|
||||
All the experiments have been rewritten for .NET 8 with C# 12 language features, so they should compile and run on the latest version of Roslyn. Have fun!
