title: How to configure multiple ASPNETCORE_ENVIRONMENT on same machine?
body: <p>I have ASP.NET core web application. I have configured the web application on our web server and set the <code>ASPNETCORE_ENVIRONMENT</code> variable to <code>Development</code>. I set this variable at machine level like shown in the picture below.
  Now on the same machine i want to configured one more instance of same web application as <code>Staging</code> environment.   </p>
  
  <p>What are my options here to set <code>ASPNETCORE_ENVIRONMENT</code> at application level instead of machine level? so i can host multiple instances of the same application on the same machine?</p>
