title: angular 6 VSTS azure Build ng build configuration=production not working
body: <p>We have upgraded to Angular 6 so we had to change the <code>ng build env=prod</code> to 
  <code>ng build configuration=production</code> because angular-cli.json is not being used anymore. </p>
  
  <p>Locally, <code>ng build configuration=production</code> works properly and the settings I need in prod were there. But when we trigger the build step/task in azure VSTS, ng build configuration=production does not replace the dev settings to production. </p>
  
  <p>Did anyone encounter this? what did you folks do to fix this?</p>
