经查阅资料发现，SQLite方法发布了对EntityFramework6支持的程序集，在项目中执行如下命令：
Install-Package System.Data.SQLite.EF6
Install-Package System.Data.SQLite.Linq
安装后会出现三个引用：
接着Web.config中配置如下：
<configSections> <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </configSections> <connectionStrings> <add name="EducationStrings" providerName="System.Data.SQLite.EF6" connectionString="Data Source=education.db;Pooling=True" /> </connectionStrings> <entityFramework> <providers> <provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" /> </providers> <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework"> <parameters> <parameter value="v11.0" /> </parameters> </defaultConnectionFactory> </entityFramework> <system.data> <DbProviderFactories> <remove invariant="System.Data.SQLite.EF6" /> <add name="SQLite Data Provider (Entity Framework 6)" invariant="System.Data.SQLite.EF6" description=".Net Framework Data Provider for SQLite (Entity Framework 6)" type="System.Data.SQLite.EF6.SQLiteProviderFactory, System.Data.SQLite.EF6" /> </DbProviderFactories> </system.data>
这样配置后，发现会抛异常信息如下：
Unable to determine the provider name for provider factory of type ‘System.Data.SQLite.SQLiteFactory‘. Make sure that the ADO.NET provider is installed or registered in the application config.
大概是说没有找个支持ado.net的管道工厂方法。在stackoverflow搜索发现，需要在Web.config中添加对System.Data.SQLite.SQLiteFactory的配置。
在entityFramework节点的providers子节点添加配置如下：
<provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />
接着在system.data节点的DbProviderFactories子节点配置如下：
<add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite"/>
这下终于支持ado.net了，但是，又会抛如下异常：
unable to open database file
大概是无法打开数据库文件，经查资料发现，程序读取SQLite数据库时需要使用物理绝对路径，解决方法有两个，一个是在代码中指定数据库配置文件，一个是在Web.config中指定一个类似变量的值，如下：
<add name="EducationStrings" providerName="System.Data.SQLite.EF6" connectionString="Data Source=|DataDirectory|\education.db;Pooling=True" />
其中DataDirectory指的是数据库的目录，对应着的是asp.net项目下的App_Data文件夹，所以，需要把数据库放到该目录。
修改完毕后又会抛另外一个异常：
SQL logic error or missing database
no such table: Articles
大概是说没有找到表Articles，我的项目用的是CodeFirst模式，看来SQLite不支持CodeFirst模式，只能手动建表了。如果表比较少或是字段比较少还行，如果有大量的表，光手动建表也得费好大事，如果能够把SQL Server 2008的数据库导入到SQLite中就好了。
经谷歌后，终于找到一个工具SqlConverter，该工具能够将SQL Server的表和表内的数据库转换成SQLite。
经转换后发现，SQLite中的主键只能是integer类型的，对应C#的int64。而我的Model却是int32，不知道是SQLite规定的还是工具转换有问题。
完整的Web.config配置如下：

这样终于可以运行了。附代码和工具。
