The usual way to do this is to derive your managed object from IDisposable

I always try to call object.Dispose explicitly when I'm done with the object, but I'm not sure that would be necessary in your case. The documentation that I've read is unclear as to whether it gurantees that Dispose() will be called before your dll unloads or not.

In my own code, the managed code domain is torn down explicitly before the unmanaged app exits so I don't have to worry about that particular problem.
