-iKVM uses a bytecode to CLR translation process that effectively converts Java bytecode directly to the .net equivalent. This is paired with a port of the Codename One API's that was built for the UWP environment. The UWP port generates native Windows 10 applications that can support ARM Windows devices natively as well as desktops etc. These binaries can be uploaded directly to Microsofts online store without special processing.

 ==== Registration
 
-When your application first opens, it needs to register with the platform's central cloud messaging infrastructure.  On Android this involves a call to their GCM/FCM server; on iOS, the call will be to the APNS server, on Windows (UWP) the call will be to the WNS server.  And so on.  That server will return a unique device ID that can be used to send push notifications to the device.  This device ID will then be passed to your `registeredForPush()` method as the `deviceId` parameter so that you can save it somewhere.  Typically you would send this value to your own web service so that you can use it to send notifications to the device later on.  The device ID will generally not change unless you uninstall and reinstall the app, but you will receive the callback every time the app starts.

 IMPORTANT: The `deviceId` parameter cannot be used directly when sending push messages via the Codename One push service.  It needs to be prefixed with a platform identifier so the that push server knows which messaging service to route the message through.  You can obtain the complete device ID, including the platform prefix, by calling `Push.getPushKey()`

+==== Historical Note About UWP Push
 
-Push on UWP requires only that you register your app in the Windows Store Dashboard.  You will then be provided with credentials (Package Security Identifier (SID) and a secret key) that you can use to send push notifications to your app.  To begin this process, go to the https://developer.microsoft.com/en-us/windows[Windows Dev Center] and select "Dashboard".

-Once you have registered your app in the Windows Store, and completed the corresponding setup in Codename One settings (e.g. generated a certificate), you should proceed to configure your app for push notifications.
-
-Navigate to the App overview page for your app inside the Windows store dashboard.  Under the "Services" menu (left side), select "Push notifications".

-You will use these two values for sending push notifications to your app.

-Microsoft provides full instructions on setting up WNS notifications https://msdn.microsoft.com/library/windows/apps/hh465407[here] but much of this is not relevant for Codename One apps.  For Codename One apps, one need only obtain Package Security ID and client secret values for the app.
