TypeScript: Unable to find reference when compiling

The Setup:
I created a TypeScript file (String.ts) to extend string:

interface StringConstructor {
    isNullOrEmpty(str: string): boolean;
    isNullOrWhiteSpace(str: string): boolean;
}

String.isNullOrEmpty = (str: string) => !str;
String.isNullOrWhiteSpace = (str: string) => { return (String.isNullOrEmpty(str)) ? false : str.replace(/\s/g, '').length < 1 };

The tsconfig.json files that I created contain:

{
  "compilerOptions": {
    "noImplicitAny": false,
    "strict": true,
    "noEmitOnError": true,
    "module": "amd",
    "removeComments": true,
    "target": "es5",
    "declaration": true,
    "outFile": "./Common.js", --> Only this line changes in other tsconfig.json files (+ does not exist in highest located tsconfig.json file)
    "inlineSourceMap": true,
    "inlineSources": true,
    "lib": [
      "dom",
      "es5",
      "es2015.promise"
     ]
  },
  "exclude": [
    "node_modules",
    "wwwroot"
  ]
}

File Structure:

The problem(in the following order)
1) When I have one tsconfig.json (highest level), everything compiles ok
2) When I add a tsconfig.json in Common, everything compiles ok
3) When I add a tsconfig.json in Business, I get a compilation error that String.isNullOrWhiteSpace cannot be found.

Anyone knows what the problem could be and how to solve it?

(If more information is needed... let me know!)

String.ts is not included in compilation when you segregate the Business directory(ie it would need to be imported from elsewhere). You should have a separate common directory called for interfaces and common definitions.
