The news just never stops does it? This time we’ve got some news for Windows Phone Developers. The Windows Phone Marketplace policies have changed! They’ve been changed to attract a wider range of developers, from large software companies to students and hobbyists.

The new Windows Phone Marketplace policies offer:

• Annual registration fee of $99
• No limit to the number of paid apps submitted 5 free apps per registration, $19.99 each after that
• Free registration to DreamSpark students (same unlimited paid and 5 free apps applies)
• A new optional push notification service to help developers stay engaged with customers
• A new optional Trial API – trials mean more customers try your app, and less likelihood that they return it. The length or type of trial is fully controlled by the developer
• The ability to publish to all available Marketplace markets through a new “worldwide distribution” option, allowing developers to pay once and distribute broadly
• Wider range of business models; free, paid, freemium and ad-funded
• Equally important to many developers is what isn’t changing:
• A revenue share of 70/30
• Developers manage their business with Marketplace via the self service portal http://developer.windowsphone.com
• Payout takes place monthly for developers that have earned more than USD$200 worldwide
• Developers can make ad funded applications
• All applications go through a process of technical and content certification
• Marketplace offers support for credit card commerce, and where available mobile operator billing.
• Microsoft continues its practice of publishing policies, guidelines, and submission process details to developers so they understand exactly how marketplace works.
