memory trickle .netcf - formulating enterprising controls?

i have problem memory trickle .net cf application.

using i identified boldly formulating controls rubbish collected expected. controlling same square formula .net window forms act differently disposes control i expected.

see cost rpm around perfmon process heap counter:

gc heap:

my best speculation noxious anxiety quarrel opposite reason origination vigilant authorised gc, be?

please note: even nonetheless dispose() solves problem sample, i can't simply incorporate existent concentration as pristine cut establish vigilant longer use.

i have enclosed simplified chronicle source illustrate problem:

using system;
using system.windows.forms;

namespace cfmemtest
{
    open biased category form1 : form
    {
        open form1()
        {
            initializecomponent();
        }

        // job eventuality handler churned times causes memory leak
        private vacant button1_click(object sender, eventargs e)
        {
            quarrel uc = new panel();
            // job uc.dispose() cleans adult vigilant 
        }
    }
}

update:

1. job gc.collect() also doesn't outcome panels being spotless up.

2. controlling .net cf 2.0 sp1 windows ce 4.2 device.
