Earlier, the Windows Phone developers were reportedly asked to pay $99 annually to get access to the Marketplace and this included up to five application (app) submissions. But, Microsoft appears to be willing to play waiting game in an effort to shore up more interest in third-party development ahead of Windows Phone 7's release by eliminating the five-app cap. Although, apparently paid apps will have unlimited submissions, but free apps would still be limited to five per annual cycle, with additional submissions costing $19.99 each.
Also, it is said that Microsoft is removing the wraps off its Trial API for encouraging developers enforce trial functionality prior to purchase, details on its push notification service, and a new option that promises to let publishers push their apps globally - to every localized store in the Marketplace's reach in one clean sweep. The company says that it has "listened to developers and responded to changing customer behavior to make Marketplace an even better experience for all," and it certainly appeals like a step in the right direction. However, we can't hide the fact - we'd still love to see free app submissions go unlimited (with a soft corner for those freebies!).
