Google and Microsoft do not get along when it comes to both Windows Phone and Windows 8. Luckily for tablet and PC users, there are numerous ways to access Google services, but if you're using a Windows Phone there have been issues in the past that hamper the user experience.
The same goes for AdSense (www.google.com/adsense), Google’s advertising network for webmasters and content creators. Unfortunately, the company has yet to release an official app for the mobile platform but Windows Phone has some talented third party developers. Cue WP Adsense.
