Hi,
I recommend you to check the Stock Trader Reference Implementation provided with Prism, as it illustrates the baseline architecture used withPrism. Also, as you may find the Prism library also includes manyQuickstartsthat could be used as a reference when building your application, although compared to the Reference Implementation these are focused on how to implement specific features of the guidance.
Additionally, I believe you could also find
David Hill's Prism Templates interesting, as they provide a starting application structure commonly used withPrism, from where you can evolve to your own requirements.
I hope you find this handy,
Agustin Adami
