Answer 1

I ran into exactly same memory leaking situation with exactly same symptoms. Here's how I handled the situation.

ElementHost class have PropertyMap property which is collection that maps WinForms control property to WPF control property.

In this particular case, memory is leaking through BackgroundImage that keeps MemoryStream instance. And so, the solution is to remove BackgroundImage property mapping:

elementHost.PropertyMap.Remove("BackgroundImage");
