Both Visual Studio 2012 and Visual Studio 2013 Preview contain a number of project and item templates designed to help you author Windows Store apps. We provide a set of templates that showcase the top Windows design patterns; however, these are meant to serve as guides and starting places for those who wish to use a pattern similar to the one expressed in the template. They’re not the only options!
In Visual Studio 2013 Preview, the default XAML templates have been redesigned to take advantage of new features introduced in Windows 8.1 Preview. As part of the redesign, we focused on two major areas: incorporating your feedback and simplifying the templates to make it easier for apps to consume them. In this blog post, we’ll describe these changes and also talk about how to upgrade your app to target Windows 8.1 Preview.
