“Addresses an issue that restores VirtualizingScrollPanel scrolling behavior
for CollectionChange event.”
I don’t see a “VirtualizingScrollPanel” class in Windows Forms or Windows
Presentation Foundation. Do you mean
System.Windows.Controls.VirtualizingStackPanel?
“Addresses Null Reference Exception when ToolTip is visible property is
overridden to be always be false.”
Which property do you mean? The System.Windows.Controls.ToolTip class does
not have a “Visible” or “IsVisible” property. There is the
ToolTipService.IsOpen attached property but I don’t understand how one could
override that to always be false.
