Developers creating apps for Microsoft’s Windows Phone 7 platform are now able to submit more free apps to the marketplace after the Redmond-based company announced it had lifted the limit from five free apps to one hundred.

Microsoft has initially placed the restriction on developer submissions to ensure the Windows Phone 7 marketplace wasn’t littered with lightweight, low-quality applications that served as “Lite” versions of its more feature-rich paid counterpart.

The limit was increased after developers submitted feedback on the matter, pressuring Microsoft to relax its rules, mainly because free and ad-supported versions of apps were beginning to outperform their paid counterparts.

With the Nokia partnership taking shape, Microsoft is going to need to do everything it can to tempt developers from Symbian to Windows Phone 7, this is definitely a good start.
