With today’s announcement of Windows 8.1 and Visual Studio 2013 availability, the Windows Store is now open for submitting apps targeting Windows 8.1. 

Here’s more from the Windows App Builder blog:

For those of you who started working on your app with our Preview versions, you’ll first need to update your Preview environment to today’s release versions of Windows 8.1 and Visual Studio 2013. Packages built on prerelease versions won’t be accepted into the Store. For apps written in HTML/JavaScript, check out our recent blog post with more specifics to help you target the release build of Windows 8.1.

If you already have an app in the Store for Windows 8 users, you’ll want to check out our info on retargeting your app. You can import your existing project into Visual Studio and make changes as needed to take advantage of the new features in Windows 8.1. After you’ve finished building, it’s easy to add your Windows 8.1 packages to your current app so that customers who’ve upgraded to Windows 8.1 see the latest version of your app. (Of course, you can also continue to update your Windows 8 apps as needed.)

For those new to the platform, take a look around the Windows Dev Center for all the resources you need to get started. You can learn what Windows Store apps are all about and get up to speed on the basics of app development. We even have content that’s specifically written to help you ramp up quickly if you’re already familiar with building apps for iOS or building apps for Android. [more]

Now ready for you: Windows 8.1 and the Windows Store
