public: static void Save( Stream^ stream, AnnContainer^ container )
This method will save the annotations to the stream using the AnnCodecsFormat.NativeXml format.
This method will not position the stream back to its original position before it returns. It is your responsibility to position the stream back before you can load objects from this stream.
For more information, refer to WPF Annotation Files.
