Base WPF Window Functionality for Data Entry

WpfWindowsLib eliminates a lot of boiler plate code needed for data entry windows. The controls verify user input (numbers, email address, phone number, ...) and inform the host window if any data has changed, i.e., saving is needed before the user can close the window. The user can only save the data once all required data is entered. Most of that functionality gets provided by just placing the controls on the window.
