App Hub is now the single place where Windows Phone and Xbox LIVE Indie Games developers can register; find development tools, support and resources; and submit and manage their apps for Windows Phone and Xbox LIVE. Every Windows Phone 7 customer will get all of their apps and games from the Marketplace Hub on their phone and from the desktop Zune software.
App Hub is another step of making it easier for you to create and distribute great apps and games across Windows Phone, Xbox 360, PC and the cloud. Additional effort will be spent on building the education catalog on App Hub so that you can find education materials centralized.
For one $99 USD Annual Subscription, you can submit apps and games through your dashboard for both the Windows Phone Marketplace and Xbox LIVE Marketplace.
It’s important to note that access is still free to DreamSpark students and that ISVs that join Microsoft Platform Ready are eligible for a $99 rebate after two WP7 applications are approved on Marketplace. Additionally by joining Microsoft Platform Ready you get additional technical and marketing support.
