分享Entity Framework4.1+MVC3+Jquery EasyUI的DEMO

花了一下午手写了这个Demo，差不多注释下，通俗易懂的Entity Framework4.1+MVC3+Jquery EasyUI的后台管理系统，现分享如下，

在WebConfig文件中修改你的配置地址就可以正常运行了

<connectionStrings>
<add name="MyProject" connectionString="Data Source=.;Initial Catalog=MyPorjectBD;Integrated Security=True;Pooling=False" providerName="System.Data.SqlClient"/>
</connectionStrings>

注意： 最好在vs2010+sql2008运行 ，不要忘记了是MVC3的环境，在项目加载成功后数据库就生成了，所以不要向我要数据库！
