title: WPF - Save user credentials at first start persistent
body: <p><strong>What is my purpose?</strong></p>
  
  <p>I would like to save user credentials at the first start of my application. </p>
  
  <p><strong>What is the starting situation?</strong></p>
  
  <p>At the first start I have a configuration dialog, which allows the support-employee of my company to configure the application firstly. At these dialog he can also set sundry credentials. I need these credentials for every user, who starts the app. (it is a network-based application)   </p>
  
  <p><strong>May some solutions?</strong></p>
  
  <p>I know, there are 'user settings' in WPF. But these are not persistent. That means, I lose the credentials, if the application is closed and another user is starting the app. But I need these credentials persistent. And for every user. </p>
  
  <p>Of course, there are also 'application settings'. But these settings I cant set dynamically at the first start of my app. So I need to set the credentials for every customer at the development and compile one executive per customer. </p>
  
  <p>Furthermore I can also save these credentials in a special database. But to create a database, only for this purpose seems a little bit to huge for me. </p>
  
  <p>Would be really nice, if somebody could help me. :-)</p>
