I trying to do a snapshot between SQLCE 3.5 SP1 and SQL Server 2008 by using the sync framework. I received a inner exception stated that "{"Unable to enumerate changes at the DbServerSyncProvider for table 'ArInvoice' in synchronization group 'ArInvoiceSyncTableSyncGroup'."}". The inner text for the inner exception stated that "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.". And the item for the inner exception indicated that "In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.". What is going wrong? Any setting i miss out?
