Microsoft.Synchronization.Data.DbSyncException：无法枚举 table 的 RelationalSyncProvider 中的更改
Microsoft.Synchronization.Data.DbSyncException: Cannot enumerate changes at the RelationalSyncProvider for table
我正在使用 MS Sync 框架 2.1，使用 sql 服务器 2008 作为客户端，使用 sql 服务器 2012 作为服务器端。
有时我会低于错误
Microsoft.Synchronization.Data.DbSyncException: Cannot enumerate changes at the RelationalSyncProvider for table 'MyTable'. Check the inner exception for any store-specific errors. ---> System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'ISyncKnowledge'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{615BBB53-C945-4203-BF4B-2CB65919A0AA}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

此应用程序 运行 同时在三台不同的电脑上运行，在两台电脑上出现相同的错误，但一台电脑没有出错并且工作正常..
任何建议..如何解决这个问题..
此处内部异常。

如果您在这些机器上安装了 SyncFx，请确保您的应用程序的目标平台与安装的 SyncFx 平台相匹配。
例如，SyncFx 的 x86 版本，您的应用也应针对 x86。
