title: When to use .NET Settings vs config <appsettings>?
body: <p>Are there any recommendations on when to use <a href="http://msdn.microsoft.com/en-us/library/aa730869(VS.80).aspx" rel="noreferrer">Application settings</a> (not per user settings) vs. .config file &lt;appsettings&gt;?</p>
  
  <p><strong>Update</strong><br>
  Looking to understand some of the finer and important differences  because they're both effectively key/value stores. 
  For example, I know modifying appsettings in web.config will recycle the web application.</p>
  
  <p>Settings have been in .NET for a while now and I haven't bothered to look at them - maybe one is somewhat redundant, or using both at the same time doesn't make sense... that's the kind of detail I'm looking to understand and the reasons.</p>
