vb.net - How do I improve performance of WPF UserControl rendered in Windows Forms -

we using wpf user controls in windows form info entry screen more 100 controls. form rendering time increased after go on usage. suggestions?

in xaml part:

grid panel arrange controls

windows form calling method:

public form new wpfusercontrol form.tag = me elementhost1.child = form form.formload()

-- more code comments --

private sub frmswitch_new_load(byval sender object, byval e system.eventargs) handles me.load public form new wpfusercontrol form.tag = me elementhost1.child = form form.formload() end sub

you creating instance of 100s command everytime call

frmswitch_new_load

but never unload new controls created. when frmswich unloads need unload wpf controls well

where give phone call frmswitch_new_load if that's load event handler form, have event handler unload event form , underthat event handler unload current wpf control
