I'm currently building a custom ServerSyncProvider I've already overrided the GetServerInfo, GetSchema and GetChanges methods, but aparently I'm not getting any session parameters on the server side, like @SyncClientIdHash or @SyncLastReceivedAnchor, that should be kept on the client (I haven't done anything alteration to my SqlCeClientSyncProvider) any idea? by the way, is there anyone crazy enough that built or is building any custom serverSyncProvider?
