Hi Guys.. These days i am interesting in windows 8 app developing because i have to create 20 windows 8 apps for Microsoft student champs .So i decided to create series of post "How to Create windows 8 app". Actually i am not going to start this in beginner level but if you requested then i can consider about it. Lets go to the my fist post in "How to Create windows 8 app" When you add commands to an app bar, consider whether your command sets would work better in a command menu. Menus let you present more options in less space and include interactive controls. In this example, the Sort menu pops up a simple list that makes choosing options easy.
