Adding, removing MenuItem, does not release memory?

[Giedrius]

Well, after developing a plugin based architecture, with lots of menuitems, i
found that after adding a menuitem, and later removing, results in increased
memory.
I know all that thing with Dispose, finalizers, garbage collector, and so
on, they do not help.

'try this, to see a how fast memory grows.

dim i as int32
Dim m As New MenuItem("ok")
for i = 1 to 10000
Me.Menu.MenuItems.Add(m)
Windows.Forms.Application.DoEvents()
Me.Menu.MenuItems.Remove(m)
Me.Text = GC.GetTotalMemory(True).ToString
next

'however other controls does not leave their stuff
Dim m As New Label
dim i as int32
for i = 1 to 10000
Me.Controls.Add(l)
Windows.Forms.Application.DoEvents()
Me.Controls.Remove(l)
Me.Text = GC.GetTotalMemory(True).ToString
next

Giedrius,

Removing memory has to do with the time it is done and the references that
are set. Therefore you can mostly not force it how hard you try, it is
managed by the framework, and two captains on a ship gives never a good
result.

Insert by instance the row I inserted in your code bellow and see the
difference. (now the label is never showed)

A link about this all is this.

I hope this helps a little bit?
