thank you

There is no property to check if your application is loaded by pressing the F5-button but you could handle the application startup event and set a variable with a datetime. The moment your page gets loaded you can check if the timespan is just a couple of seconds ago. So now you know that the application is loaded the first time or the F5-button is pressed when that time it is only a couple of seconds ago. I don't know if this is sufficient for you but you can give it a try:

App.xaml.cs

public class App : Application
{
 private DateTime appStartupTime {get; set};
 public App()
 {
     Startup += new EventHandler(Application_Startup);
 } 

 void Application_Startup(object sender, StartupEventArgs e)
 {
   //initialize the startupTime
   appStartupTime = DateTime.Now; 
 }
 public bool IsApplicationReLoaded
 {
   get
   {
     //return true if your app is started less 10 seconds ago
     return DateTime.Now.AddSeconds(-10) < appStartupTime;
   }
  }
}

Now you can start using the code below from everywhere

(Application.Current as App).IsApplicationReloaded
