The execution order of asynchronously called methods

When I call several methods on the Dispatcher, say UI Thread Manager,

like here

uiDispatcher.BeginInvoke(new Action(insert_), DispatcherPriority.Normal);
uiDispatcher.BeginInvoke(new Action(add_), DispatcherPriority.Normal);
uiDispatcher.BeginInvoke(new Action(insert_), DispatcherPriority.Normal);

will these methods be executed in the same order in which they were called?

With the help Dispatcherthey will be executed in the same order in which they were called, but only because DispatcherPriority- the same. This is guaranteed behavior and is described in Dispatcher.BeginInvoke :

If multiple BeginInvoke calls are made with the same DispatcherPriority, they will be executed in the order in which the calls were made.
