View and ViewController destructor #8

Closed LucaFagan closed 5 years ago

LucaFagan commented 5 years ago

Hi, when GoBackCommand is invoked are the top view and associated view model destroyed ?

For example, if view1 is initial view and I navigate to view2, when I go back to view1, is view2 destroyed and when ? I have made same tests and destructors are never called.

Hi,

The history does not save instances, just page names (strings), so when navigating back the initial view is destroyed. Try forcing garbage collection with

GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();

Hi, you are right, forcing GC destructors are fired.

Thanks for the reply.
