  <p>"Sets mode for compiling the application.<br>
  Choose among<br>
  <strong>Active (Debug)</strong>,  &lt;========<br>
  <strong>Debug</strong>,           &lt;========<br>
  Release,<br>
  All Configurations."  </p>
  
  <p>It appears that <strong>Active (Debug)</strong> and <strong>Debug</strong> are two separate choices.<br>
  However, the MSDN library fails to explain the difference between  <strong>Active (Debug)</strong> and <strong>Debug</strong>.  </p>
  
  <p>There's no information here:  "Visual Studio Debugger
  Project Settings for C# Debug Configurations"  </p>

  <p>I could not find any explanation via Google either.</p>
  
  <p>QUESTION:<br>
  What is the difference between  <strong>Active (Debug)</strong> and <strong>Debug</strong>?</p>
