When is the Window.SourceInitialized event raised

问题

Can I guarantee the Window.SourceInitialized event will always be raised before the Window.Loaded event? I need the HwndSource object for further processing in my Window.Loaded event handler and I'm not sure if this will always be available by then

Here's the sequence of events you can expect (it should occur before Loaded):

If you want to double-check, or don't trust getting the SourceInitialized event...then you can try and obtain the HwndSource yourself....to see if it's connected.
