c# - Memory leak when I select uwp listbox item frequently -

-



i create listbox , register it's selectedchanged event. don't in event handler. , write ui automation test,it can select listbox's item in turn frequently. (there 5 items in listbox);

when test running.i watch app's private memory.it increased.

but when test over.the private memory hold , doesn't been collect. if use memory profiler in visual studio force gc.collect().

so think makes memory leak.

could me ? thanks.
