I have built application for Windows Phone 8.1 and upload it to Store.
Now I created version for Windows Phone 8.0
Can I have them as one application in Store?
And if so what should I do?
I have an app that has different versions for Windows Phone 7 and Windows Phone 8 but is visible as one in Store. I hope it works for Windows Phone 8.1 as well.
Log in to your Dev Center account and open your app details page. Click Update app, then go to Upload and describe your package(s) section. And here's the point. Instead of replacing the existing package, just click Add new. You'll have two packages, but it will be one app in Store. Windows Phone 8 users should see the new version you want to upload and Windows Phone 8.1 users will have the old one without changes. None of them would see both version.
