What is the UWP Async work running sequence

Question

I'm curious if the work submitted by CoreDispatcher::RunAsync is running in FIFO order. It seems I can't find the document about this. Can someone clarify this for me ? Many thanks!

I'm curious if the work submitted by CoreDispatcher::RunAsync is running in FIFO order.

It seems that the documentation does not specify that CoreDispatcher::RunAsync runs in FIFO order. But we can find ProcessEvents method explanation. Starts the dispatcher processing the input event queue for this instance of CoreWindow.

And the queue represents a first-in, first-out collection of objects. So we can regard CoreDispatcher::RunAsync as running in FIFO order.

Update1

as @IInspectable comments below, CoreDispatcher::RunAsync contains a CoreDispatcherPriority argument. And we often use Normal priority that delegates are processed in the order they are scheduled.
