New Post: ModalContentPresenter with Caliburn.Micro

I have found the ModalContentPresenter class presented at http://programmingwithpassion.wordpress.com/2012/07/01/displaying-modal-content-in-wpf/ .

Unfortunately, the code conventions are not working for controls defined as childs of the ModalContentPresenter.

Example (without ModelContentPresenter, working):

<Window>
    <Button x:Name="SomeName"/>
</Window>

Example (with ModelContentPresenter, not working):

<Window>
    <c:ModelContentPresenter>
        <Button x:Name="SomeName"/>
    </c:ModelContentPresenter>
</Window>

What I need to do to get the code conventions working?

Thanks.
