<p>I need to be able to control/track child containers. The easiest way to do that would be to inherit UnityContainer and override CreateChildContainer.</p> <p>&nbsp;</p> <p>However, none of the methods in UnityContainer is virtual and it&#39;s therefore impossible (without using &quot;new&quot; which is more of an hack).</p> <p>&nbsp;</p> <p>Please enable extension through inheritance</p>
