为什么LinqPad可以在我的控制台应用程序中连接Db。 抛出相同代码的SQL异常？

Question

I run the code below

var connectionString="Data Source=MyFooServer.myDomaion.com;Initial Catalog=FooDb;Integrated Security=True; MultipleActiveResultSets=true";

using (var con = new SqlConnection(connectionString))
{
    var q = "SELECT COUNT(*) FROM Pizza";
    SqlCommand cmd = new SqlCommand();
    SqlDataReader reader;
    cmd.CommandText = q;

    cmd.CommandType = CommandType.Text;
    cmd.Connection = con;
    con.Open();

    reader = cmd.ExecuteReader();
    con.Close();
}

from 2 different places:

1) LinqPad

2) A Console application in Visual Studio 2010

LinqPad works fine. No exceptions. But the same code throws an SQL exception : "The target principal name is incorrect. Cannot generate SSPI context."

QUESTION: Why I can connect to my database without any problem from LinqPad but not from the console application even tough I run the same code?

Answer 1

重新启动我的机器有帮助...不知道造成此行为困难的根本原因是什么。

Answer 2

尝试使用SQL用户名和密码代替Windows Inegrated Security。

var connctionString="Data Source=MyFooServer.myDomain.com;Initial Catalog=FooDb;Uid=Username; pwd=password"
