  • Provided you are using version 3.5 of SQL Server Compact - you can use Merge Replication (requires SQL Server Standard or better) or Sync Framework. Or you can roll your own web services.

  • Hi ErikEJ

    here is some code roughly coded to test the synchronization between sdf file and server file

    SynchronizationSyncAgent syncAgent = new SynchronizationSyncAgent();

    Microsoft.Synchronization.Data.SyncStatistics syncStats;

    provided paths of the databases.....

     syncAgent.LocalProvider = syncProviderClient;
     syncAgent.RemoteProvider = syncProviderServer;

     syncAgent.clientDB.SyncDirection = Microsoft.Synchronization.Data.SyncDirection.Bidirectional;

    and given remaining tables..

    syncStats = syncAgent.Synchronize();----- Exception MissingMethodCaught Exception

    I m getting and error in the above line as

    Method not found: 'Boolean System.Data.SqlServerCe.SqlCeChangeTracking.UpgradePublicTracking(System.String)'.

    Can u please help me out how to clear this exception.

  • are you running SQL CE 3.5 SP2?

    check that you have the matching SQL CE and Sync Framework versions.

  • Hi June T

    i think your right..

    I m using

    1. Sync Framework 1.0 SP1

    2. SQL Server Compact 3.5 SP1

    3. Visual Studio 2010

    let me know if SQL Server Compact 3.5 SP2 is upgraded, will the exception will be cleared and sync data??

  • if you refer back to the matrix, Sync Framework 1.0 SP1 requires SQL Server Compact 3.5 SP2

  • if you have set your adapters correctly, that looks fine. if you've used the Local Database Cache wizard, then it looks fine as well.

    have a look at this tutorial:  Walkthrough: Creating an Occasionally Connected Application
