In search of a WPF application to illustrate Teststack.White usage

I am looking for a fully functional WPF application that I can use to demonstrate the functionality of Teststack.White and the PageObject/ScreenObject pattern. Ideally, this application wouldn't have any online dependencies (as I want to be able to demo the project in an offline environment) and have most of its UI controls mapped with AutomationId's.

A lot of the WPF examples I've found online either don't compile with VS2015/VS2013, are empty graphical shells without business logic or are too trivial to illustrate more complex test design (ie Windows Calculator...)

I've been contemplating to write my own example application, but I don't want to reinvent the wheel as I think there probably will already be tens (if not hundreds) of commercial/freeware/open-source WPF applications available that meet my requirements.

One application I've found that almost fits the bill is CCleaner, but regretfully they have little AutomationId mappings for their UI controls.
