title: Silverlight to WPF: Windows authentication
body: <p>I am attempting to convert a Silverlight application to WPF.  I control web access to the Silverlight application and its APIs by requiring Windows Authentication in IIS.  This works well, even for non-local, non-domain computers accessing the app, as the user's web browser automatically prompts for the user's credentials.</p>
  <p>I cannot figure out any way to have a WPF application running on a non-local, non-domain computer access these same remote web server APIs that are protected by Windows Authentication in IIS.  Does anyone have any code examples of how this might be done from a WPF application?</p>
  <p>I need the WPF app to request the user's credentials, and use those credentials in accessing the WCF services running under an IIS site that has (only) Windows authentication enabled, from a non-domain computer.</p>
