CoreCLR is the execution runtime for .NET Core, containing the garbage collector, JIT compiler, primitive data types, and low-level base classes. The repository has been consolidated into dotnet/runtime and is no longer actively developed here.
Use cases
- run and execute .NET Core applications
- understand how the .NET garbage collector works
- contribute to or study the .NET JIT compiler
- debug low-level runtime issues in .NET Core apps
- build a custom .NET runtime from source
When to choose
- you need the historical CoreCLR source for research or archaeology
- you are studying runtime internals, GC, or JIT design
- you maintain a fork or legacy .NET Core 1.x/2.x build
When to avoid
- you want to develop or contribute to the current .NET runtime - use dotnet/runtime instead
- you just need to run .NET apps - install the official .NET SDK/runtime
- you need a supported, up-to-date runtime with security fixes
