The AutoUpdater Developer Samples will not compile in ArcFM.
The MMAutoUpdaterClass class was removed from the API in ArcFM 10.1. Bug MM49994 has been submitted to correct the developer samples and documentation.
The following code may be used to replace this class:
Type type = Type.GetTypeFromProgID("mmGeodatabase.MMAutoUpdater");
object obj = Activator.CreateInstance(type);
IMMAutoUpdater autoupdater = obj as IMMAutoUpdater;
The new AutoUpdater class in Miner.Geodatabase may also be used for this purpose.
