I run two instances of VS 2015, the second one instance is attached to XDesProc.exe (Xaml Designer) of the first one VS 2015 instance and breakpoints in user control code behind file are inactive after opening xaml file in Xaml Designer on first instance of VS 2015 (I ran VS 2015 with admin privileges also).
Is it possible to debug UWP xaml controls in design mode at all (when xaml designer claims the control throws some exceptions and can't be instantiated)?
