sql-server – 尝试读取或写入连接到SQL Server的受保护内存

这是我获得的错误：

Failed to connect to server MYSERVER. (Microsoft.SqlServer.ConnectionInfo)

ADDITIONAL INFORMATION:

Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (System.Data)

我在行使实体框架运行任何查询时碰着此错误,譬喻这样的任何一行：

var AllRows = context.MyTableRows.ToList();

我以为这是一个EF题目,但其后我实行行使VS2012中的Transact Sql编辑器毗连到数据库,这样我就可以查询它,并在实行毗连时碰着同样的错误.

但我有其他非Microsoft查询器材可以毗连到数据库并查询它,而不会导致错误.以是我以为题目出在Microsoft驱动措施或System.Data.SqlClient的某个处所,但我无法弄清晰题目出在那边.

更新：我实行在LinqPad中毗连到统一台处事器,当我实行毗连它时,它就会挂起.

更新：仓库跟踪很长,看起来像这样：

…我的应用措施中实行执行EF查询的行…

办理要领

netsh winsock重置

然后重启.
