Changes to tsconfig.json not picked up

[mhegazy]

// a.ts
Symbol.iterator;

{
    "compilerOptions": {
        "lib": [
            "es5",
            "dom"
        ]
    }
}

1. open 'a.ts', there should be an error for missing Symbol definition
2. change lib in tsconfig.json to include es6, and save
3. make an edit in a.ts. expect the error to go away

Actual:

Error does not go away, closing and reopening the file does.

Expected:

Error goes away on next refresh.

@mhegazy Were you able to verify yourself that the issue was fixed?

I can repro this with VS 2017 Update 2. Changes to tsconfig.json are not picked up until I close and reopen main.ts.

tsconfig.json

{
  "compileOnSave": true,
  "compilerOptions": {
    "outDir": "../../wwwroot/js",
    "removeComments": false
  }
}

main.ts

export class Main
{
    // test comment
    constructor() {
        console.log("inside constructor");
    }

    foo(): void {
        console.log("inside foo");
    }
}

Changing the value of "removeComments" doesn't have any effect on the output until I've closed, reopened and re-saved the source file.

Looks fixed in Update 3. give it a try.
