Access App instance from MainWindow instance

Question

Is it possible to access App instance from MainWindow instance?

My App performs some initialization steps (like configuration initialization) and I need to pass the config to MainWindow.

App.Current should return this instance, you will need to cast it though.

Oh, thanks, cannot realize that I can cast it. Well, before I checked you (15 mins cap) - is it possible to access MainWindow from App? I bet it is not, but just to be sure ;-)

Yes you can, somewhat, but you need to make the MainWindow the actual main window of the application by using the Application.MainWindow property, otherwise you can try and find it in the Windows collection of the application for example by checking the types of the windows.

the issue is - in App.Init() method .MainWindow hasn't been initialized yet...

Then you need to work with calls from the window to the app i suppose.

yup, that is why I asked about Window -> App direction in initial question ;-) Thanks for your help.
