title: Building Ionic 4 Cordova Universal Windows App shows White Screen
body: <p>I am attempting to build an Ionic 4 application with Cordova 6. The build is successfully using </p>
  
  <pre><code>ionic cordova run windows -- --arch"x64"; 
  </code></pre>
  
  <p>however the screen is always white. I tried to open up all the polyfills to see if that was the issue but no luck. 
  I have also updated my config.xml file to add the following:</p>
  
  <pre><code>&lt;platform name="windows"&gt;
  &lt;preference name="windows-target-version" value="10.0" /&gt;
  &lt;platform/&gt;
  </code></pre>
  
  <p>When i try to open the .sln project into visual studio code 2017 i get tons of ignored icons on the files. 
  Any help would be amazing. </p>
