What happens inside the CLR from compilation to execution? Explain the full pipeline.

Expert C#

Answer

The CLR pipeline includes:

  • C# code parsed by Roslyn into IL + metadata.
  • IL stored in assemblies (.dll/.exe).
  • CLR loads assemblies via Assembly Loader and verifies IL.
  • JIT compiles IL to native machine code using RyuJIT and tiered compilation.
  • Execution occurs under GC, exception handling, and type-safety rules.
  • Supports JIT, AOT, ReadyToRun, and NativeAOT execution models.
