【中文标题】企业库缓存到本地数据库【英文标题】：enterprise library cache to local database 【发布时间】：2014-03-14 15:52:49 【问题描述】：

我正在尝试找出是否可以使用 entlib 缓存块缓存到本地数据库（SQL Server Compact 3.5 数据库），但是我没有任何教程或示例；仅适用于 MSSQL 服务器。我的脚本有很多问题，因为 SQL Compact 不支持很多功能：

任何人有任何想法，链接或任何东西？！

【问题讨论】：

我认为这会很难，因为 SQLCE 中不存在存储过程 【参考方案1】：

如您所见，SQL CE 不支持某些功能，因此无法使用 Entlib 缓存。

如果您尝试将数据缓存在本地 SQL CE 数据库中，那么还有其他选择。

你可以试试 MS Sync 框架http://msdn.microsoft.com/en-us/library/ee617382.aspx

这里有一篇关于如何做到这一点的文章：http://www.codemag.com/article/0712092

【讨论】：

我需要 entlib 提供的灵活性！【参考方案2】：

如上所述，SQL CE 中不存在存储过程，因此必须探索其他选项
