Menu
I'm creating a standard menu in my WPF application.
I know that I can create custom commands, but I know there are also a bunch of standard commands to bind to.
For example, to open a file I should bind to ApplicationCommands.Open, to close a file I should bind to ApplicationCommands.Close. There's also a large number of EditCommands, ComponentCommands or NavigationCommands.
There doesn't seem to be an "Exit" command. I would have expected there to be ApplicationCommands.Exit.
What should I bind to the "Exit" menu item? To create a custom command for something this generic just seems wrong.

We can close the window either by using "this. Close()"or by using "App. Current. Shutdown()".
The proper way to shutdown a WPF app is to use Application. Current. Shutdown() . This will close all open Window s, raise some events so that cleanup code can be run, and it can't be canceled.
The command is the action to be executed. The command source is the object which invokes the command. The command target is the object that the command is being executed on. The command binding is the object which maps the command logic to the command.
Unfortunately, there is no predefined ApplicationCommands.Exit. Adding one to WPF was suggested on Microsoft Connect in 2008: http://connect.microsoft.com/VisualStudio/feedback/details/354300/add-predefined-wpf-command-applicationcommands-exit. The item has been marked closed/postponed, however.
Mike Taulty discussed how to create your own Exit command in an article on his blog.
