Introduction:
It is time to write an article about "How to get OS Version in Winrt platfrom?", previously in silverlight platform(WP8.0/WP8.1) we can easily get windows phone device OS version with 'Environment.OSVersion', unfortunately now in winrt platfrom 'Environment' class doesn't have property like 'OSVersion'. However we have an alternative way, and we can learn it from this article :)
