Memory leak reloading list items on Windows

[sjorsmiltenburg]

Description

The most important problem I face with my app is that it keep increasing it's memory usage.
At least one of the causes seem to be that my app has a collectionview that is bound to a grouped collection that needs it's
items to be reset multiple times (every time you come back to the screen).

I'm using the latest 8.0.0-rc.9373

I have tried to make a test sample that illustrates the problem.

This is a screenshot of the memory increase of my own application, not the test application.

Steps to Reproduce

start bugs project
click on bug8 button
keep pressing the reload button and watch memory increase.

I am having these issues as well and it's not only for collectionview. After ContentPage/ContentView loaded, basically adding/deleting/replacing control object will increase the memory and they don't drop till you quit the app.

use case - grid control
step 1 - on the page, user click on button to add items (any child element) to the grid then remove all.
setp 2 = repeat step 1 for sometimes and call GC.Collect().

I have upgraded my sample project to use the latest net 9.0 preview and maui preview, but the memory leak still occurs
