| Era | Tool | Primary Use‑Case | Limitations | |---|---|---|---| | | ILDasm | Static disassembly of assemblies | No runtime info, no JIT data | | .NET 4‑4.5 | CLRProfiler / PerfView | Process‑wide ETW tracing, limited IL exposure | Heavy, Windows‑only | | .NET Core 2.0 | dotnet-trace (EventPipe) | Collects runtime events, can include JIT/IL events | Requires ETW/EventPipe knowledge | | .NET 5‑8 | Microsoft.Diagnostics.Runtime (ClrMD) | Programmatic inspection of live processes, heap, and JIT metadata | Still requires custom code to extract IL | | Modern | System.Reflection.Metadata + System.Reflection.MetadataLoadContext | Pure‑managed, cross‑platform IL reading | Doesn’t give JIT‑time data by itself | | AOP/Weaving | Mono.Cecil , Fody , PostSharp | Insert custom IL‑level instrumentation | Adds build‑time complexity | : Key characteristics of MSIL: using System; using
