Microsoft's Windows Phone Marketplace has now hit 100,000 applications. After reaching 50,000 apps in late December, the Marketplace has doubled in size in six months to reach a new milestone for Microsoft's mobile operating system. The software giant revealed the news during its Windows Phone Summit today in San Francisco.

Questions still remain on the availability of big name Windows Phone apps and quality over quantity, but Microsoft is clearly attracting more and more developers to its mobile platform. Alongside the milestone announcement, Microsoft also revealed that Draw Something and Word with Friends, are coming to Windows Phone devices soon.
