#Steps to reproduce

• Use VSCode (version shouldn't matter)
• Open an angular application
• Have a tsconfig.json file that conforms to TypeScript's spec, but is not valid JSON (with an extra , before a closing } for example)

Current behavior

Expected behavior

Because TypeScript allows this file, the language service should allow it as well

Any updates? as i see in vscode-extension github repository
too many issues regarding broken extension

and i believe that folk put forward a bunch of false ideas (reinstall extension an so on)

whereas in many cases the problem lies in this issue

it seems if typescript supports json5-like format this package should too
