What is this?
CoreCLR is the runtime for .NET Core — the component that actually executes .NET Core programs. It ships the garbage collector, the JIT compiler, primitive data types and low-level classes.

Other parts of the platform lived in sibling repos — CoreFX for the libraries — until everything was merged in the big consolidation.

This repo only holds the source and is archived, so there is nothing new to install from here.

This repo only holds the source and is archived, so there is nothing new to install from here.Is CoreCLR still developed here, or is the project finished?Development here has ended: the repository is archived and frozen. The .NET team consolidated its GitHub repos and moved the code and issues formerly handled here — see dotnet/announcements#119.

App developers just use the .NET runtime and never need this repo.

Primitive types and low-level classes form the foundation.

Its source history stays browsable, while current .NET runtimes come from the consolidated repositories.
