Hello App Studio Users!
As we focus on building universal Windows apps that run on any phone, tablet, or PC running Windows 8.1, we will remove support for Windows Phone 8.0 app generation in App Studio. All the apps you have created can be used to generate universal apps. In addition, all the previous versions generated targeting Windows Phone 8.0 will be still available to download as source code, publish, or installable package. However, if you plan on making updates to App Studio apps targeting Windows Phone 8.0, we encourage you to update and generate before December 17th, 2014.
What does this mean for mean for my Windows Phone 8.0 apps I have created in App Studio?
You can still download the source code, publish package, and installable packages of the apps you created targeting Windows Phone 8.0. All past projects apps will continue to be able to be improved and edited; however, to generate apps with those changes, they will have to be generated as universal Windows project targeting Windows Phone 8.1 and/or Windows 8.1.
Will I be able to have access to my past 8.0 versions?
Yes, you will be able to still access these through your Generation History and you can download the source code, publish package, and installable packages.
What does this mean for mean for my Windows Phone 8.1 and Windows 8.1 apps that I have created in App Studio?
There will be no changes Windows and Windows Phone 8.1 app creation and generation in Windows App Studio.
