Context: #23166
This expands upon #23166 (iOS/Catalyst memory leaks for
TabbedPage
),fixing the same problem on Windows. I could reproduce the problem in
MemoryTests.cs
.I found the
NavigationViewItemViewModel.Data
property held theContentPage
that held onto theTabbedPage
. I made the backing fielda
WeakReference
and the test inMemoryTests.cs
now passes on Windows.
