The Universal Windows Platform has been touted as nirvana for developers wanting to build applications that run anywhere.

Often the first point of discussion is how to design applications that scale across the wide variety of target devices. What is often forgotten, at least until very late in the development process, is how to build an application that is going to be both highly responsive and high performing.
