Helper class for dispatcher operations on the UI thread.

Executes an action on the UI thread. If this method is called from the UI thread, the action is executed immendiately. If the method is called from another thread, the action will be enqueued on the UI thread's dispatcher and executed asynchronously. For additional operations on the UI thread, you can get a reference to the UI thread's dispatcher thanks to the property .

The action that will be executed on the UI thread.

This method should be called once on the UI thread to ensure that the property is initialized. In a Silverlight application, call this method in the Application_Startup event handler, after the MainPage is constructed. In WPF, call this method on the static App() constructor.

Gets a reference to the UI thread's dispatcher, after the method has been called on the UI thread.

This can be used to bind any event on any FrameworkElement to an . Typically, this element is used in XAML to connect the attached element to a command located in a ViewModel. This trigger can only be attached to a FrameworkElement or a class deriving from FrameworkElement. To access the EventArgs of the fired event, use a RelayCommand<EventArgs> and leave the CommandParameter and CommandParameterValue empty!
