“App.Current.myProperty” does not work, but “((app)Application.Current).myProperty” does

问题

I have my own public property in App object. But it doesn't work while I trying to access it via App.Current.myProperty. it work only via ((app)Application.Current).myProperty. I see a lot samples where people use App.Current to access own properties. Did I missed something? Override Current property?

回答1:

Yes, you should add your own Current property into your App class.

That's because it by default Application.Current returns Application class instance, not your derived class.
