title: Project build halts on: "Build delayed until Bower/npm packages finish restoring."
body: <p>In VS 2017, I created a new ASP.NET Core Web Application using the Angular template.</p>
  
  <p>The project however does not run, it gets stuck on:</p>
  
  <pre><code>Build delayed until Bower/npm packages finish restoring.
  </code></pre>
  
  <p>I see that a background task is running, but this goes on for ever and doesn't make any progress.</p>
