Question

今天我部署了我的第一个asp.net mvc3网站。似乎与数据库的连接不起作用。我需要说，我是web.config文件配置的新手。我从VS 2010部署了alle文件，可以访问不使用数据库的站点。我使用Entities.edmx.sql文件创建了数据库。所有表格都已创建。

VS 2010中的Web.config：

<?xml version="1.0" encoding="utf-8"?>

我知道我需要关闭customErrors模式。我的主机给了我以下连接字符串来使用。我试图将它用于ApplicationServices和EntitiesContainer，但它没有用。

workstation id=the_workstation_id;packet size=4096;user id=username;pwd=password;data source=data_source_name;persist security info=False;initial catalog=catalog_name

我得到了这个例外：
