Have you ever wanted to cross-promote your apps? I used to maintain a list of my apps within those same apps! What a pain that was. Every time I released a new app I needed to update my other apps. There must be a better way!
Two years ago I wrote an article for Coding 4 Fun called Let Your Apps Sell Themselves. Today, I massively updated the code and create a Nuget package to simplify its use. Check it out!
Among other things, it has a WP7 and WP8 version, it looks at the current version of the device it's actually running on to determine which apps to show, and it is localized for Spanish (more languages coming soon).
