vscode does not pickup tsconfig.json files in subdirectories

[CoreyCole]

According to @mjbvz in #4466

[vscode does pick up] tsconfig.json files in subdirectories and treat those subdirectories as individual projects. If you are not seeing the correct behavior around this, please open a new issue and I can take a look

• VSCode Version: 1.23.1
• OS Version: OSX 10.13.4

Steps to Reproduce:

1. clone https://github.com/CoreyCole/tsconfig-bug
2. open vscode at the root, open another vscode window in the subdirectory tsconfig-bug
   • install node modules in subdirectory
3. see the root window has red lines in tsconfig-bug/test/app.e2e.spec.ts but in the subdirectory window the typing information is correct

You can see me reproducing the issue

Does this issue occur when all extensions are disabled?: Yes

This is unrelated to the tsconfig. That file is not part of any tsconfig because you have excluded it with the include and exclude rules.

The issue you are seeing is that we don't load global types (like those used by jest) from node_modules in sub folders by default. You can fix this by adding:

import 'jest'

to the file. Or by making the file part of a real tsconfig that contains:

 "typeAcquisition": {
    "include": [
      "jest"
    ]
  }
