xaml code:

<flipview x:name="imageflipview">    <image source="ms-appx:///assets/caffe600320.jpg" stretch="fill" />    <image source="ms-appx:///assets/cafee2.jpg" stretch="fill" />    <image source="ms-appx:///assets/caffe3.jpg" stretch="fill" /> </flipview> 

code behind:

private splashscreen splash; // variable hold splash screen object internal bool dismissed = false; // variable track splash screen dismi internal frame rootframe; private readonly dispatchertimer _timer;  public extendedsplash(splashscreen splashscreen, bool loadstate) {     this.initializecomponent();     statusbar statusbar = statusbar.getforcurrentview();     statusbar.hideasync();     if (splash != null)     {         splash.dismissed += new typedeventhandler<splashscreen, object>(d     }     rootframe = new frame();     _timer = new dispatchertimer     {         interval = timespan.fromseconds(2)     };     _timer.tick += changeimage;     _timer.start(); }  private void changeimage(object sender, object e) {     var totalitems = imageflipview.items.count;     var newitemindex = (imageflipview.selectedindex + 1) % totalitems;     imageflipview.selectedindex = newitemindex; }    void dismissedeventhandler(splashscreen sender, object e) {     dismissed = true;             }
