The unmanaged objects are released right away, that's how Dispose always works.

The GC will remove the object, as all references have expired.

At this point, Finalise is called, which should clean up the same stuff Dispose does, you call Dispose to have stuff cleared without waiting for GC.

If you forgot to call Dispose it will still be called from the garbage collector when it gets arround to release the object.

MSDN says:

Do not assume that Dispose will be called. Unmanaged resources owned by a type should also be released in a Finalize method in the event that Dispose is not called.

      // the finalizer call - they might already have been released.<br />

      // Tell the Garbage Collector it no longer need to finalize this, if<br />
      // this isn't done, the object will end up being promoted a generation<br />
