我尝试在同步代码中使用SqlCeSyncProvider，但它会出现错误SqlCeSyncProvider dos not exist, Are you missing assembly reference。 MSDN SqlCeSyncProvider Microsoft.Synchronization.Data.SqlServerCe using Microsoft.Synchronization.Data.SqlServerCe; using Microsoft.Synchronization.Data.SqlServerCe.SqlCeSyncProvider; The type or namespace name 'SqlCeSyncProvider' does not exist in the namespace 'Microsoft.Synchronization.Data.SqlServerCe' (are you missing an assembly reference?)

我尝试了2.0.0.0,3.1.0.0和3.5.0.0版本的程序集，但不了解可能出现的问题。我也尝试使用 using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
using Microsoft.Synchronization;
using Microsoft.Synchronization.Data;
using Microsoft.Synchronization.Data.SqlServer;
using Microsoft.Synchronization.Data.SqlServerCe;
namespace ExecuteExpressSync
{
class Program
{
static void Main(string[] args)
{
SqlConnection clientConn = new SqlConnection(@"Data Source=.\SQLEXPRESS; Initial Catalog=SyncExpressDB; Trusted_Connection=Yes");
SqlConnection serverConn = new SqlConnection("Data Source=localhost; Initial Catalog=SyncDB; Integrated Security=True");
// create the sync orhcestrator
SyncOrchestrator syncOrchestrator = new SyncOrchestrator();
// set local provider of orchestrator to a sync provider associated with the
// ProductsScope in the SyncExpressDB express client database
syncOrchestrator.LocalProvider = new SqlSyncProvider("ProductsScope", clientConn);
// set the remote provider of orchestrator to a server sync provider associated with
// the ProductsScope in the SyncDB server database
syncOrchestrator.RemoteProvider = new SqlSyncProvider("ProductsScope", serverConn);
// set the direction of sync session to Upload and Download
syncOrchestrator.Direction = SyncDirectionOrder.UploadAndDownload;
// subscribe for errors that occur when applying changes to the client
((SqlCeSyncProvider)syncOrchestrator.LocalProvider).ApplyChangeFailed += new EventHandler<DbApplyChangeFailedEventArgs>(Program_ApplyChangeFailed); // Error on this line
// execute the synchronization process
SyncOperationStatistics syncStats = syncOrchestrator.Synchronize();
// print statistics
Console.WriteLine("Start Time: " + syncStats.SyncStartTime);
Console.WriteLine("Total Changes Uploaded: " + syncStats.UploadChangesTotal);
Console.WriteLine("Total Changes Downloaded: " + syncStats.DownloadChangesTotal);
Console.WriteLine("Complete Time: " + syncStats.SyncEndTime);
Console.WriteLine(String.Empty);
}
static void Program_ApplyChangeFailed(object sender, DbApplyChangeFailedEventArgs e)
{
// display conflict type
Console.WriteLine(e.Conflict.Type);
// display error message
Console.WriteLine(e.Error);
}
}
}
，但它给出了错误

这是否意味着Microsoft doc是错误的？
