title: How to access app configuration from a .dll?
body: <p>I recently broke out a part of my winform app in a .dll. Some of the classes in that dll
  wants fetch/store user settings. 
  The classes just used the VS generated Settings file so it just did 
  <code>Properties.Settings.Default.SomeSetting = var;Properties.Settings.Default.Save()</code> etc.</p>
  
  <p>What are my options now that I moved that code out to a class library/.dll ?</p>
