title: Azure Web App doesn't build typescript files
body: <p>I have an ASP.NET Core project which has this structure:</p>
  
  <pre><code>- tsconfig.json
  - app
   |- file1.ts
   |- file2.ts
   |- file3.ts
  - wwwroot
   |- app
   |- index.html
  </code></pre>
  
  <p>tsconfig has these contents:</p>
  
  <pre><code>{
    "compilerOptions": {
      "noImplicitAny": false,
      "noEmitOnError": true,
      "removeComments": true,
      "sourceMap": true,
      "target": "es6",
      "module": "amd",
      "outFile": "wwwroot/app/app.js",
      "strictNullChecks": true
    },
    "compileOnSave": true
  }
  </code></pre>
  
  <p>When I try to deploy this project from git to Azure Web App my .ts files don't get compiled. I thought Kudu can deal with Typescript already. Am I missing something?</p>
