title: IIS AppDomain instantiation
body: <p>I have a web site and a web service under the same virtual directory and some of the web pages call the web service. </p>
  
  <p>When the web service is called, does IIS create a new AppDomain or does it run the web service in the same AppDomain?</p>
  
  <p>Is there a setting for this? On one of my machine it appears to create a new AppDomain. Does changing application pool mode from Integrated vs Classic affect this?</p>
