The Windows Store blog announced today that the store is now open to a massive number of developers, from across 120 different markets. From their post:
Today’s an especially great day to be a developer. We’re very excited to announce the last significant milestone in the rollout of the Windows Store before the general availability of Windows 8 on October 26. The Store is now open for app submissions from all developers – individuals and companies – in our supported markets, and we’ve added 82 more app submission markets! Now, developers from 120 markets can publish Windows Store apps.
As per the license:
All eligible MSDN subscribers receive a free, one-year Windows Store developer account as part of their MSDN benefits. (Eligible subscriptions include Visual Studio Professional, Test Professional, Premium, Ultimate, and BizSpark.) We have a program for students—DreamSpark—that similarly waives the subscription fee. And we have an offer for businesses in our BizSpark program, as well.
Or you can pay 170 nis (aprox 40$) and get your own license.
