CoreCLR

This folder contains the source for CoreCLR, the .NET runtime implementation used by most workloads. CoreCLR tests live in ../tests (the src/tests subtree).

Building and testing

See the workflow docs for the authoritative instructions — they cover the specific subset, configuration, and incremental-iteration flags that the top-level build.sh/build.cmd help text does not. For up-front baseline build requirements (mandatory under CCA, probe-and-fall-back under CLI), see .github/copilot-instructions.md.

• Building CoreCLR
• Testing CoreCLR
• Test configuration options
• Unix test instructions · Windows test instructions
• Disasm checks · GC stress runs
• Using corerun and Core_Root

Some subdirectories contain their own README.md with component-specific guidance — read any you find before making changes.
