Starting today, any qualifying business in a supported market can now submit a Metro style app for Windows 8! Companies qualify through account registration, which includes an account verification process.
Just so you know, to upload apps to the Store, you’ll need an RTM build of Windows 8. On August 15, we’ll be making the build available to MSDN subscribers and we’ll have a trial version available via TechNet. (Keep your eyes here and on the Windows 8 app developer blog for more info.) Until then, keep building your apps using the Release Preview, and don’t hesitate to register your company account now—it takes a little time to get a company account verified. Registering now will help ensure you can hit the ground running when the RTM build is released.
If you’re an individual looking to submit apps to the Store, stay tuned—we’ll have more info to share with you soon.
