我是这个世界的新手，坦率地说，我不喜欢它的复杂性，除此之外怎么样。连接到.sdf
我创建了一个名为Sample.sdf的新数据库，然后我创建了一个新的ASP.NET MVC3应用程序。我在读，你必须将.sdf数据库复制到项目的根目录。所以我这样做了，我试图创建一个新的ADO.net连接到这个紧凑的数据库，但我应该这样做吗？
我不能在web.config中使用连接字符串对象并将其配置为指向该数据库吗？如果有，有没有办法测试连接？
我很好奇，因为我打算在实体框架中使用它。
更新：
所以我想通了一些东西出来：
其中.sdf已进入App_Data文件夹，然后从他们的基础上创建的一个ADO.net实体模型现有数据库。它会自动查看数据库，并为您完成剩下的工作，或者至少在我的情况下它已经完成。
然而，它抛出一个错误，当点击下一个实体数据模型向导，艇员选拔我的数据连接后，我得到了：
Unable to create new database.

我真的不知道如何着手。
发生'SqlException'是因为您尝试使用* full-blown * SQL Server类连接到您的SQL Server ** Compact **数据库 - 这是行不通的。当你创建实体数据模型时，你没有选择'SQL Server Compact'作为你的数据库类型，或者你的连接字符串被其他方式弄坏了。 – 2013-04-10 16:12:23
