entity-framework - 此操作需要连接到 'master' 数据库

Question

我的应用程序突然开始出现错误。

错误是:

This operation requires a connection to the 'master' database. Unable to create a connection to the 'master' database because the original database connection has been opened and credentials have been removed from the connection string. Supply an unopened connection.

代码中没有任何变化 - 其余代码中的数据库访问都很好。

它停在这条线上:

var filteredContacts = dc.EAContactLists.Where(o => teams.Contains(o.Team)).ToList();

我迷失在这一点上。

Answer 1

尝试设置 Persist Security Info = True在您的连接字符串中。

希望这可以帮助。
