Temple Run for Windows Phone in the Marketplace.

Last June Microsoft announced that its Windows Phone Store was home to more than 100,000 applications. That wasn't too shabby at the time considering that the operating system was still relatively new in the grand scheme of mobile operating systems. Now, however, in conjunction with the launch of the Lumia 928 on Verizon, Microsoft and Nokia revealed that Microsoft's app store now has 145,000 apps.

That means the company, in just about a year, only added 45,000 applications while competing stores such as Android Play and the iTunes App Store quickly move past the 700,000 app mark. That suggests that the growth of Microsoft's app store has slowed drastically. Does Microsoft have a developer problem? Perhaps—hopefully we see new applications such as Instagram hit soon.
