Final Release Com Object(Object) Method
Releases all references to a Runtime Callable Wrapper (RCW) by setting its reference count to 0.

static member FinalReleaseComObject : obj -> int
Public Shared Function FinalReleaseComObject (o As Object) As Integer
The RCW to be released.
The new value of the reference count of the RCW associated with the
o parameter, which is 0 (zero) if the release is successful.
o is not a valid COM object.
When the reference count on the COM object becomes 0, the COM object is usually freed, although this depends on the COM object's implementation and is beyond the control of the runtime. However, the RCW can still exist, waiting to be garbage-collected.
The COM object cannot be used after it has been separated from its underlying RCW. If you try to call a method on the RCW after its reference count becomes 0, a InvalidComObjectException will be thrown.
