FIX: Non-convergence occurs when you synchronize a SQL Server Compact 3.5 client database with the server by using Sync Services for ADO.NET in a Hub-And-Spoke configuration

Extended support for SQL Server 2005 ended on April 12, 2016

If you are still running SQL Server 2005, you will no longer receive security updates and technical support. We recommend upgrading to SQL Server 2014 and Azure SQL Database to achieve breakthrough performance, maintain security and compliance, and optimize your data platform infrastructure. Learn more about the options for upgrading from SQL Server 2005 to a supported version here.

You use Microsoft Sync Services for Microsoft ADO.NET to set up a bidirectional synchronization in a Hub-And-Spoke configuration. You set up a Microsoft SQL Server Compact 3.5 database as a client database. When the synchronization starts, non-convergence occurs. Additionally, some changes in the client database are not uploaded to the server. When you run the following query against the client database, values of the __sysChangeTxBsn column and of the __sysInsertTxBsn column in the sync table incorrectly roll back to a smaller value:
SELECT __sysChangeTxBsn, __sysInsertTxBsn, UserActivityId, ActivityDate FROM <Sync Table>WHERE __sysInsertTxBsn IS NOT NULLORDER BY ActivityDate ASC
However, you expect that the values will increase because these columns are of the Timestamp data type.
This problem occurs because the metadata in the client database of SQL Server Compact Edition is maintained incorrectly.
To work around this problem, do not use the Compact method on the client database. However, because this is not always possible, a hotfix has been provided.
