WebCIL loader for CoreCLR is gated behind #ifdef TARGET_BROWSER and there are open questions.

  • Should we keep it behind #ifdef TARGET_BROWSER and have browser specific SOS binaries ?
  • Or we should remove #ifdef TARGET_BROWSER ?
  • Where the debugger takes the DLLs from ?
  • Is it reading DLLs (before transform to WebCIL) or the actual .wasm files ?
  • How do the .DLL/.wasm files get from (browser ??) into the debugger
