title: Accessing the settings (app.config) of the calling application
body: <p>I have a WinForms application ("WF"), and a Library called by that WinForms application ("LIB")</p>
  
  <p>WF has a Settings.settings (Visual Studio Designer) and app.config combo. I gather than the designer is a front end that auto generates the app.config file. To use those settings from within WF, I use the strongly typed properties of the class it autogenerates (i.e. WF.Settings.MyTimeOutSetting).</p>
  
  <p>When WF calls a method in LIB, I want to use one of WF's settings from within lib. How can I retrieve a setting from the caller's (WF's) app.config while in the callee's (LIB's) code?</p>
