There are many dos and don'ts in Windows Phone UI development. It is good to remember that we have a screen with a limited size where the elements should be placed comfortably.
This is the main goal of Windows Phone UX. Starting with the phone menu, we can switch between tiles and application lists; if we touch an element action it is performed very fast. We have to remember while creating our own software about providing responsivity to user interaction; even if we need to load some data or connect to a server, the user has to be informed about the loading. Going through our application, the user should feel that he or she controls and can touch every element. Many controls provide animation out of the box and we need to use it; we need to impress our users while seeing motion in our application. The application has to be alive!
