• Automates most of the upgrade steps – doesn’t do everything!
• Converts .csproj to UWP, updates package.appxmanifest
• Run directly in Powershell (needs script execute allowed), or execute
Run_Upgrade_to_UWP.bat at cmd prompt

this.Page.Loaded += (sender, e) =>
{
#if WINDOWS_PHONE_APP
Windows.Phone.UI.Input.HardwareButtons.BackPressed += HardwareButtons_BackPressed;
#else
// Keyboard and mouse navigation only apply when occupying the entire window
if (this.Page.ActualHeight == Window.Current.Bounds.Height &&
this.Page.ActualWidth == Window.Current.Bounds.Width)
{
// Listen to the window directly so focus isn't required
Window.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated +=
CoreDispatcher_AcceleratorKeyActivated;
Window.Current.CoreWindow.PointerPressed +=
this.CoreWindow_PointerPressed;
}
#endif
};
Example:
protected override void OnNavigatedTo(NavigationEventArgs e)
{
var frame = Window.Current.Content as Frame;
if (frame.CanGoBack)
{
SystemNavigationManager.GetForCurrentView().AppViewBackButtonVisibility =
AppViewBackButtonVisibility.Visible;
}
else
{
SystemNavigationManager.GetForCurrentView().AppViewBackButtonVisibility =
AppViewBackButtonVisibility.Collapsed;
}
SystemNavigationManager.GetForCurrentView().BackRequested += Page_BackRequested;
}
var api = "Windows.Phone.UI.Input.HardwareButtons";
if (Windows.Foundation.Metadata.ApiInformation.IsTypePresent(api))
{
Windows.Phone.UI.Input.HardwareButtons.CameraPressed
+= CameraButtonPressed;
