公司提供给我的连接字符串是：

<add name="SiteSqlServer" connectionString="Server=(127.0.0.1);Database=DATABASENAME;uid=DBUSERNAME;pwd=DBPASSWORD;" providerName="System.Data.SqlClient" />

我的web.config文件中的那个是相同的。我已经创建了一个数据库，它可以很好地使用我机器上的默认连接字符串。

一个可能的原因：

使用WebSecurity类进行身份验证时遇到此错误。检查过滤器文件夹中的属性类，该属性类在帐户控制器上使用。此类用于初始化WebSecurity类，但具有引用“DefaultConnection”的默认构造函数调用。将其更改为web.config的connectionstrings部分（在您的情况下为“SiteSqlServer”）中的连接字符串的名称，它可以解决问题。
