## What it is
A sandbox repository for experimenting with new library ideas for the .NET ecosystem, related to the corefx codebase. It is now archived, with experiments moved to dotnet/machinelearning and dotnet/runtimelab.

## Use cases
- explore experimental .NET library prototypes
- find historical corefx experiment code
- study early .NET API designs
- locate where .NET team experiments moved

## When to choose
- you need to reference archived experimental .NET code
- you want to trace the origins of APIs that later shipped in .NET

## When to avoid
- you want actively maintained .NET libraries
- you need production-ready code
- you want current .NET experiments (use dotnet/runtimelab instead)

## Facets
- artifact type: library
- maturity: abandoned
- function: developer-tools, sdk
- domain: developer-tools, programming-languages
- platform: dotnet, cross-platform
- tags: corefx, experimentation, archived, c-sharp, sandbox
