    Hello I made a sample that is able to synchronize between sql server 2008 and SDF local database but I just wanted to change the client side

    part of this sample to be able to use sql server 2008 in local side ?

    what is the main step for that .

     

    here is some code that trigger the synchronization

     

    ServerSyncServiceProvider serverProvider = new
 ServerSyncServiceProvider(Properties.Settings.Default.Server_WarehouseDBConnectionString);
   SqlSyncProvider localprovider = new
 SqlSyncProvider(""
, new
 SqlConnection(Properties.Settings.Default.Client_WarehouseDBConnectionString));

   SyncOrchestrator sync = new
 SyncOrchestrator();
   sync.RemoteProvider = serverProvider;
   sync.LocalProvider = localprovider;
   sync.Direction = SyncDirectionOrder.Download;
   SyncOperationStatistics stats = sync.Synchronize();

     

    of course I'm using wcf service to call the remote database server

     

    and locally i'm just using an SqlSyncProvider that connect to sql server 2008

     

    but I got this exception :

    InvalidCastException Was not unhandled: Microsoft.Synchronization.KnowledgeSyncProvider

     

    !!!

    the tracking table contains the tombstones as well. the trackings contains the change tracking information so it will have a row for each row in the base table so Sync Fx can determine if a row has been inserted/updated/deleted. the tracking table is populated by triggers on the base table.

    check How to: Clean Up Metadata for Collaborative Synchronization (SQL Server) in the docs as well as the Tuning and Monitoring Performance topic.

    is ServerSyncServiceProvider  a custom provider? if you're synching both SQL Server 2008 on server and client, why dont you just use SqlSyncProvider on both sides?

    ServerSyncServiceProvider

    public partial class ServerSyncServiceProvider : Microsoft.Synchronization.Data.Server.DbServerSyncProvider

    I created LocalDataCache File and this class generated but then I wanted to use it to synchronize with sql server database not SDF file

     

    so I tried to modify the code as the question above ,,,, anyway ,, could you give some sample in how to use SqlSyncPRovider in both sides

     

    and I would like to remind you that I call the  Server side by using WCF

     

    thanks a lot ,

    good to hear you've made some progress.

    the Local Database Cache uses a different provider and you cant mix and match the offline provider (SqlCeClientSyncProvider/DBServerSyncProvider) and the collaboration provider  (SqlCeSyncProvider/SqlSyncProvider)

    the documenation actually has step-by-step tutorials on both type of providers.

    finally I have a big achievement I modified this sample to fit my needs

    http://code.msdn.microsoft.com/sync/Release/ProjectReleases.aspx?ReleaseId=3762

    but I noticed something strange for me ! : tracking table contains the same number of rows for the relative data table .

     

    I'm still beginner so I don't know why and when I configured the local database and server database for the first time , no Thumbstone tables created ?

    - well thanks for this information but don't you think that this will cause to enlarge the size of the database in all sides (server , clients ) and is there any optimization tips when using it with Sql server 2008 of course I don't want to use other sync frame work techniques I mean I have to use the change tracking tables and the provisioning sync classes in general

    exactly like this famous sample : http://code.msdn.microsoft.com/sync/Release/ProjectReleases.aspx?ReleaseId=3762

    I am facing the same issue, can you elaborate what really helped you solving the InvalidCastException because that sample link is no longer accessible. Note that I am also using WCF proxy in n-tier configuration.
