Hello all,

Im developing a mobile device app,and im using syncframework to sync .sdf database on device with sql server 2008 in server. Im using WCF service library as a middle tier. I have a large number of rows and tables to sync,and i get an out of memory exception. I updatet the code using datasetsurrogate but i get the exception again.Is there any solution for this? I also tried with resultset instead of dataset,but nothing changed.

Thanks in advance.

here is the article i used to do the datasurrogate,and it depends on a ms wlakthrough http://jtabadero.wordpress.com/2010/03/08/sync-framework-wcf-based-synchronization-for-offline-scenario-%E2%80%93-using-custom-dataset-serialization/[^]

       public SyncContext GetChanges(SyncGroupMetadata groupMetadata, SyncSession syncSession, [System.Xml.Serialization.XmlElementAttribute(DataType = "base64Binary")] out byte[] dataSetSurrogateByteArray)
       {

           object[] results = this.Invoke("GetChanges", new object[] {
                       groupMetadata,
                       syncSession});
           dataSetSurrogateByteArray = ((byte[])(results[1]));
           return ((SyncContext)(results[0]));
       }
