One of my favorite features of XAML is the ability to provide design-time data. This feature is present in WPF, Silverlight, and of course Windows Store apps. The great thing about design-time data is that the developer can create it programmatically when needed or the designer can generate some through Blend. In this post I will share an example of generating design-time data through code. The example is a project I am working on for my upcoming book, and can be downloaded from the website (still in its very early stages) from CodePlex.
