While developing UWP application I recently found quite a few memory leaks preventing my pages from being collected by GC. I have a ContentPresenter on my page like: <ContentControl Grid.Column="0" Grid.Row="1" Content="{x:Bind ViewModel.Schedule, Mode=OneWay}"> </ContentControl> After I remove the Content, or replace it with dynamic {Binding} -- page is collected when I navigate from it. Otherwise it remains in memory. Is it bug or I'm doing something wrong? Is there a way to release and clear ALL the bindings on navigating from? UPDATE: It seems to be a known problem inside Microsoft as was

I'm tying to figure out how to use the GridView with different classes for groups. In the GridApp template everything inherits from SampleDataCommon, do you always have to inherit from a common class in the GridView? The documentation seems.. lacking on this mater. UPDATE: Specifically the problem I'm trying to solve is to have a GridView with both image tiles and text news articles. You can bind to any class type. I would suggest that they implement a common interface or class. If they cannot, then grouping them just does not make sense. You can display the items within the group by using a

I am trying to use WinRTXamlToolkit.Controls.DataVisualization.UWP trying to draw any of the stacked charts like this: But only this comes out: Please help me, I have to use stacked series but the framework doesn't act as it should be..
