Prism Quick Start Kit
A number of solution and project templates for Visual Studio that would give you a simple working app that you could tweak and modify. These would fall somewhere in-between the Quick-Starts and Reference Implementation and provide a basic solution and project structure into which you could add your application specific files.
The quick-start solution is meant to provide a basic structure for a Prism app and to include the most commonly used features of Prism. I find it very useful as a starting point because it contains all of the little code snippets and that you often need and has a basic structure in place making it pretty straightforward to take it and modify it to create many different types of applications. It’s hopefully also a good place to experiment with Prism and to learn about some of its basic features.
