ConcurrentModificationException, classe (Microsoft.Office.Server.ApplicationRegistry.Administration)

Article

The Business Data Catalog administration object model uses an optimistic concurrency model. Each object has a version associated with it in memory. When it is written to disk via an Update, the version number in memory is compared with the version on disk, and is incremented if they are the same. The update is failed by throwing this Exception if they differ; the user must .Read() the object from disk, discarding the current in memory changes and then retry the update.
