Some Background

I have noticed that setting the EditTemplate of a DataForm (from the Silverlight Toolkit) can cause the DataForm to not be garbage collected. Consequently, the parent control of the DataForm cannot be garbage collected either, causing a very significant memory leak.

Here's some XAML which demonstrates the case.

    <toolkit:DataForm HorizontalAlignment="Stretch" Margin="10" VerticalAlignment="Stretch">
        <toolkit:DataForm.EditTemplate>
            <DataTemplate>
                <toolkit:DataField Label="Dummy Binding:">
                    <TextBox Text="{Binding DummyBinding, Mode=TwoWay}" />
                </toolkit:DataField>
            </DataTemplate>
        </toolkit:DataForm.EditTemplate>
    </toolkit:DataForm>

I have opened an issue on CodePlex. The isssue has an attachment which has a project which desmonstrates the case.

So, My Question Is

Has anyone else encountered this issue? More importantly, does anyone know of any workarounds? How can I force this DataForm to be garbage collected?
