ADO.NET Entity Framework 如何：手动定义模型和映射文件（实体框架）

本主题介绍如何手动创建 AdventureWorks 销售模型 模型和映射文件。 如果手动生成模型和映射文件，则仍需要将 Visual Studio 项目配置为使用实体框架。有关更多信息，请参见 如何：手动配置实体框架项目。

说明：

如果在 Visual Studio 项目中使用实体数据模型向导，则该向导会自动生成 .edmx 文件并将该项目配置为使用实体框架。有关更多信息，请参见 如何：使用实体数据模型向导（实体框架）。

创建存储架构定义语言 (SSDL) 文件

• 将名为 AdventureWorks.ssdl 的文件添加到您的项目目录中并粘贴以下内容：
