[1]WPF Apps With The Model-View-ViewModel Design Pattern: [2]WPF: If Carlsberg did MVVM Frameworks: Part 3 of n, [3]Introduction to Attached Behaviors in WPF (Josh Smith), [4]Using ValueConverter and MultiValueConverter in WPF, [5]Showing Dialogs When Using the MVVM Pattern - By disore, [7]Using a Service Locator to Work with MessageBoxes in an MVVM Application - By Josh Smith. The ServiceLocator class is static which means that it is initialized and loaded as soon as the .NET Framework loads the corresponding namespace. It turns out that using these classes for the first time is simple (thanks to Disore's article and source code). How would I handle User Control that has a timer? Disore [5] shows different ways for creating this map in his article. There are several execution paths for shutting down the main window, and through that, the application.

Summarizing the concept - there is one static class, the ServiceLocator [7] which is used to register the DialogService class and the WindowViewModelMappings class. Looking back on it, and having seen some other articles on similar topics [5], - I have realized that I stumbled into a "CodeProject trap" that snaps shut because some topics, such as, MVVM, are not so well defined and some patterns are quite different when being applied to solve different requirements. The important thing this property does is, when it is set to true, it attaches an event handler to the Closing event of the window. This is done in such a convoluted way because I want to make sure that all shut down requests are handled by one method (App.OnSessionEnding()). It is null by default and is set to true or false when the user closes the application via Cancel or OK. Window.
