I would recommend doing 2 things:

1. implement the Dispose pattern with a Finalizer in the managed code class
holding onto the unmanaged object - see more at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpgenref/html/cpconFinalizeDispose.asp

2. call Marshal.ReleaseComObject on the unmanaged object until the
ReferenceCount is zero. When you refer to a RCW (runtime callable wrapper),
COM increments the reference count on the object and thus holds onto the
memory for that object.
