App Submission Tips for Windows Phone 7 and 8

There was a great post today on the Windows Phone Developer Blog regarding app submission. The highlight of the post was the added ability to associate multiple XAPs with the same app GUID. I won’t copy the entire post here, but below are a few things you need to think about when submitting your apps. This is straight from the post on WPDB. Check out the full blog post here.

“Here’s how to decide on your approach:

  1. If you already have a Windows Phone 7 app and don’t want to take advantage of the new app functionality available in Windows Phone 8, you can choose to leave your app as it is. Windows Phone 8 devices are designed to run existing Windows Phone 7 apps. Therefore, your app will be visible to all Windows Phone users, including Windows Phone 8 users. We do recommend that you test your 7.x app in the Windows Phone 8 emulator, to confirm that it works properly.
  2. If you already have a Windows Phone 7 app and want to leverage the exciting new Windows Phone 8 features, expanded markets, and languages of the Windows Phone 8 platform, you can upgrade your app to Windows Phone 8 and maintain the existing app GUID. However, please note that this will result in your app not being visible for users of Windows Phone 7 devices.
  3. The final option is to add a second XAP to the app GUID of your Windows Phone 7 app. Just make a copy of your 7.x XAP and then upgrade the copied XAP to Windows Phone 8. In Dev Center you will now see an Add new option on the Upload your XAP page. This allows you to add additional XAPs to the app that have different binaries and their own long descriptions.”
