title: Visual Studio not compiling TypeScript
body: <p>I have a Visual Studio project with a structure like so:</p>
  
  <p><a href="https://i.stack.imgur.com/AQn7A.png" rel="noreferrer"><img src="https://i.stack.imgur.com/AQn7A.png" alt="Folder structure"></a></p>
  
  <p>My <code>tsconfig.json</code> looks like:</p>
  
  <pre><code>{
    "compilerOptions": {
      "noImplicitAny": false,
      "noEmitOnError": true,
      "removeComments": false,
      "sourceMap": true,
      "target": "es5",
      "outDir": "../wwwroot/"
    },
    "exclude": [
      "node_modules",
      "wwwroot"
    ]
  }
  </code></pre>
  
  <p>However, VS isn't compiling the <code>app.ts</code> into the <code>wwwroot</code> folder.</p>
  
  <p>What am I missing?</p>
