步骤2：这时，我们可以通过使用微软的一个方便管理扩展及DLL的工具NuGet去获得Entity Framwork框架(当然也可以到微软的主页上去下载)，关于NuGet，可以参考其网站：http://nuget.org/。我们这里到打开Library Package Manager –> Manage Nuget Package Manager，输入搜索Entity Framwork，即可下载该框架，如下图：
当选择并点安装后，会发现在工程项目中，已经新增了相关的框架类库，如下图：
步骤3：现在我们建立数据库表，将表命名为customers，建表脚本如下：
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Customer](
[CustomerId] [int] IDENTITY(1,1) NOT NULL,
[FirstName] [nvarchar](50) NULL,
[LastName] [nvarchar](50) NULL,
[Address] [nvarchar](256) NULL,
[City] [nvarchar](50) NULL,
CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED
(
[CustomerId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Customer](
[CustomerId] [int] IDENTITY(1,1) NOT NULL,
[FirstName] [nvarchar](50) NULL,
[LastName] [nvarchar](50) NULL,
[Address] [nvarchar](256) NULL,
[City] [nvarchar](50) NULL,
CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED
(
[CustomerId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
