When my WPF application is open, and I open a Remote Desktop Connect to my PC, WPF reloads the application (Unload and Load events on the main control are triggered). When I disconnect, this happens again.
I understand that the UI has to be redrawn, but why is the control reloaded? Can this be prevented? Or is there a way to detect if a reload is triggered by an RDP (dis)connect?
Interesting question, i don't know why this happens, but with some code from this page http://blogs.msdn.com/b/jgoldb/archive/2010/02/27/optimizing-visual-studio-2010-and-wpf-applications-for-remote-desktop.aspx I think that you can understand if a (Un)Loaded is triggered by Remote Desktop.
I could fix the problems with my application by unsubscribing the Load-event at first execution and move deinit code from the Unloaded-event to the Exit-event.
