Out of interest why doesn't the interop layer, which is generated by VS or tlbimp, use the Disposable pattern on the generated wrapper objects? This implementation could then call Marshal.ReleaseComObject(this) to release the underlying COM reference.
It would seem an ideal place to use this but perhaps I�m missing something oblivious?
