Typically, in an MVVM Light application, the DispatcherHelper is initialized in App.xaml.cs, which is the file defining the startup class of the application. In Windows Phone, you call DispatcherÂ­Helper.Initialize in the InitializePhoneApplication method, right after the applicationâs main frame is created.
A Dispatcher is also created when you create a DispatcherObject. If you create a Dispatcher on a background thread, be sure to shut down the dispatcher before exiting the thread. If a Dispatcher is shut down, it cannot be restarted. In WPF, a DispatcherObject can only be accessed by the Dispatcher it is associated with. For example, a background thread cannot update the contents of a Button that is associated with the Dispatcher on the UI thread.
