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+sql2008R2(2005也行)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！
