title: aspnetcore rc2 Local.pubxml How to setup environment during publishing?
body: <p>I'm trying to publish my aspnetcore rc2 website using Local.pubxml to IIS.</p>
  
  <p>The problem is that I want to change the environment so that I can use <code>env.IsDevelopment()</code> and other nice features.</p>
  
  <p>For now, I don't know how to change ASPNETCORE_ENVIRONMENT for:</p>
  
  <ol>
  <li>Local.pubxml - Development environment</li>
  <li>Test.pubxml - Staging environment</li>
  <li>Live.pubxml - Production environment</li>
  </ol>
  
  <p>Is that possible?</p>
