As of recently (two weeks) I noticed that a WPF applications take more time to appear on screen, even though the window has already initialized and loaded (events have fired). After the Loaded event has been raised it takes 4 to 4.5 seconds before the Activated event has been raised and the window is visible on screen.
This issue is reproducable with a new WPF application project. The windows event logs also show no warnings or errors regarding this. I have also ran 'ngen update'-command but nothing seems to change.
I don't know what other steps I can to undertake to find and fix this issue, but it interrupts fast development iterations. Any advice regarding this would be appreciated.
