Remote performance monitor

Question

Hello.

I try to use Remote Performance Monitor to understand memory leaks in my
application.
In my application i create a class "Pippo" and another class
PippooList:List<Pippo>.
In my forms i use these objects for the logic of my app.
After some creation and use of my objects in the remote performance monitor
when i press the "View GC Heap" i see
the root of the objects in the Garbage Collectior Heap.

In the statistics group i see that the number of instancies of Pippo is 0
and then i think that i use correctly my objects (The GC have collected my
objects).
But i see that there is a type called "Pippo[]" with 1 instance of 12 bytes.
If i see the roots tree i see that the instance is in the form of:

[roottatic (System.Collections.Generic.List`1<Pippo>)] Pippo[]

The number of instancies of System.Collections.Generic.List`1<Pippo> is 0.

Is that right?
What is the meaning of the Pippo[] instance?

Thanks in advance.

Simon.
