Microsoft released in 2012 their new operating system called Windows 8. This system just redefined a lot of functions / features, compared to the previous versions, which are really important changes for both users and developers. It has a brand new, innovative UI (which can be familiar from Windows Phone 7) and now they are focusing on the user and the user experience, because they should be open to the consumer world. The new operating system works not just in PC enviromnent, it works on tablets and mobile devices, because it runs on AMR architecture as well, which can be a great opportunity for developers.
At the end there will be the final application (ready to be uploaded to the store), of course the summary of the development experiences and the future development possibilites.
