DbSyncException

A synchronization is already in progress.

This property is used when an application requires that changes be delivered in batches. Batching is useful in scenarios similar to the following one:

  • A large number of clients that use SqlCeSyncProvider synchronize periodically with a server that uses SqlSyncProvider.

  • Each client has a limited amount of memory and disk space.

  • The connections between the server and clients are low bandwidth and intermittent, often resulting in long synchronization times and dropped connections.

  • The size of the changes (in KB) for a typical synchronization session is large.

Consider potential side effects when choose a batching directory. For example, when the provider is hosted by Internet Information Services (IIS), do not use an IIS virtual directory as the batching directory. IIS can trigger a restart when changes are made to items in a virtual directory, which causes synchronization to fail.
