title: VS CODE error S5057 cannot find a tsconfig.json file at the specified directory: '.'
body: <p>I am having fits getting visual studio code going with my angular 2 starter project.  </p>
  
  <p>I have set up my <strong>tsconfig.json</strong> like so ...</p>
  
  <pre><code>    {
    "compilerOptions": {
      "target": "es5",
      "module": "system",
      "moduleResolution": "node",
      "sourceMap": true,
      "emitDecoratorMetadata": true,
      "experimentalDecorators": true,
      "removeComments": false,
      "noImplicitAny": false
    },
    "exclude": [
      "node_modules",
      "typings/main",
      "typings/main.d.ts"
    ]
  }
  </code></pre>
  
  <p>Immediately I came across this error </p>
  
  <pre><code>  [ts] Experimental support for decorators is a feature that is subject to change in a future release. Set the 'experimentalDecorators' option to remove this warning.
  class AppComponent
  </code></pre>
  
  <p>I could not identify what was going on so I ran a build and got this error.</p>
  
  <pre><code>error TS5057: Cannot find a tsconfig.json file at the specified directory: '.'
  </code></pre>
  
  <p>This error explains why I am getting errors about the component decorator, but I am not sure why the <strong>tsconfig.json</strong> file is not being found.</p>
  
  <p>I only have one folder and it is holding everything except index.html, package.json and .gitignore.   </p>
