I'm testing out the docking with the docking panes in VB.NET, and i'm doing very simple behavior. I simply create panes over and over (about 30), then I simply click on the 'X' of each pane to close all the panes. And of course I have the following code to destroy the pane:

Private Sub DockManager_Action(ByVal sender As Object, ByVal e As AxXtremeDockingPane._DDockingPaneEvents_ActionEvent) Handles DockManager.Action

   If sActions(e.action) = "PaneActionClosed" Then
     DockManager.DestroyPane(e.pane)
   End If

End Sub

Before continuing, sActions in the above code is simple and array of strings in case anyone is wondering. Now here's the problem, the memory NEVER goes down, keeps on rising on this very simple test. Do these controls leak ??? Am i doing something wrong ???

Your code is right.

it is .NET.

Nobody know when .NET core free memory. Don't worry about it.

try to manually free garbage collection:

GC.Collect()
