Question

I am using Microsoft Sync framework and this issue has no clear solution in Google.

I am trying to create a client provider for SQLServer Client as below

`public class SampleClientSyncProvider : SqlSyncProvider`

But I am running in to invalid cast exception when setting the ‘localprovider’ below

Exception:

System.InvalidCastException was unhandled
Message=Microsoft.Synchronization.Data.ClientSyncProvider
Source=Microsoft.Synchronization.Data

Code called:

 public class SampleSyncAgent : SyncAgent
{
    public SampleSyncAgent()
    {
        this.LocalProvider = new SampleClientSyncProvider();

Please help if you can ..

Answer 1

The SyncAgent works out of the box only with SqlCeClientSyncProvider/DbServerSyncProvider.

SqlSyncProvider works with SyncOrchestrator.

check in the docs on the difference between offline providers and collaboration providers.

I suggest you use the SqlSyncProvider/SyncOrchestrator instead.
