How to publish a Windows 8.1 store app to cover the old version for Windows 8 app RRS feed

  • Question

  • Hi, 

    We need to publish a Windows 8.1 store app which is a Universal app, and there has have a Windows 8 app in store , we completely rewrite the application and now we hope user can upgrade it from old version other than install a new one. We plan to emulate the updating process but didn't find any methods.

    do you have any ideas about this?

  • Hi,

    The scenario of the Windows 8/8.1 app is that- (VS=Visual Studio)
    -If the app is build in VS2012 in Windows 8 then it will available for both Windows 8 and Windows 8.1 users
    -If the app is build in VS2013 in Windows 8.1 then it will available only for Windows 8.1 users only.

    You can use the Visual Studio 2013 Express (free available) in Windows 8.1 and retarget the old Windows 8 app to Windows 8.1 by following this link https://msdn.microsoft.com/en-us/library/windows/apps/dn263114.aspx?f=255&MSPPError=-2147217396

    The user will now get-
    -Windows 8.1 app if running Windows 8.1
    -Windows 8 app if running Windows 8

    Basically if you want to develop/give updates simultaneously to users then use VS2012 and VS2013 on Windows 8.1 and work on both to have universal apps.

  • Thanks for replying,

    what I am worry about are :

    1, A new app will be installed after user upgrade from store,

    2, or user need re-login after user upgrade  from store,

    because the new packages is completely different with the old one, the system would recognize the packages as the different app or the old database or settings would be covered by the new one.

  • Hi,

    1. You can give updates to users but remember the best way is that when you submit the app, then always give upgrade in the already existing app name in Windows Dev Center. Now the user will get update of existing app automatically in Windows 8.1 only (because Universal app not available for Windows 8).

    2. For re-login, if your existing app has already a database then surely it'll recognize old database if you maintain the compatibility with older one with same app as mentioned in (1.) and also with same app architecture & language.
