Quick Answer
Your C# code is compiled by Roslyn into IL (Intermediate Language) stored in an assembly. At runtime, the CLR loads the assembly, verifies the IL, then JIT-compiles it to native machine code on first execution. From then on, the native code runs directly. GC, exception handling, and type safety are managed throughout.
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.
