Silverlight control not being garbage collected because of command

My control is bei开发者_如何学编程ng kept alive because of command it is bound to. How can I break this reference? This is causing a major memory leak in my application. The control is inside of a DataTemplate so I have no direct access to it.

Here is my ANTS memory profile:

How on earth do I break this connection?

Though I incorporated WeakEventListener, I discovered that my problem was with the control I was using to wrap up my images. I was hooking it up to DownloadProgress, ImageOpened, and ImageFailed events and never unhooked them. My thinking was that nothing else in my code was touching the BitmapImage objects so they would be garbage collected with the control. This, it sees, is not the case. The BitmapImage objects were referenced by a static member (and therefore a GC root) deep within Microsoft's code called "ManagedPeerTable.PeggedManagedPeersWithRefs". It was so deep that a Google search returned only five results for it. Now I suppose there will be six.
