title: How to do simple user login in UWP (Universal Windows Programming) app
body: <p>I want to make UWP app. In which user will login using username/password. Using these credentials an API will be hit. Which will return authenticated user. if authenticated user is returned then his profile page is shown.  otherwise he should stay at login screen. Also there are more screens in my app. User data should be retained on each screen. and if new user logs in his corresponding data should be shown. </p>
  
  <p>Since I am from asp.net background. Here are my questions.</p>
  
  <p>1) Is this approach fine in UWP?</p>
  
  <p>2) Where to save user data after login?</p>
  
  <p>3) Should I save it using SQLlite or In-memory?</p>
  
  <p>4) Is there any concept like Session In Websites so that I can get logged in user on each page</p>
  
  <p>5) Also How to make this app to run of fix resolution (800 x 600)</p>
  
  <p>Any help on this is appreciated. Sample code will be more helpful.</p>
