Additional Information

The geometry library methods do not cause the exception. An ArcObject coclass instance must be created on the thread calling the methods on that instance interfaces. The instance cannot be created on one thread and accessed by another thread. Serialize an instance into a memory blob in one thread, and de-serialize it from the memory blob on another thread, and then call the methods on the de-serialized coclass.
