title: How can I verify that my async/await is using I/O completion port?
body: <p>I am currently converting a database stored procedure call to be asynchronous, leveraging async/await. Similar to the method described <a href="http://www.hanselman.com/blog/TheWeeklySourceCode51AsynchronousDatabaseAccessAndLINQToSQLFun.aspx" rel="nofollow noreferrer">here</a>.</p>
  
  <p>Based on <a href="https://stackoverflow.com/a/9434687/142794">this answer</a>, I'd like to verify that asynchronous call is actually using I/O completion ports. If it's ultimately waiting on another thread from the ThreadPool, then it is effectively defeating the purpose of converting the call.</p>
  
  <p>What is the best way to verify that an I/O completion port is being used and it's not simply blocking on another thread?</p>
